E. Longmeadow, MA –Motion Control – LM76 has developed the most corrosion resistant linear bearing available. In space, deep under the sea, or in the harshest environments, when there can be no “Plan B,” Pegasus Series 1 Linear Ball Bearings can be counted on to perform. In some applications linear bearings will not move for days, weeks, months or even years, however, when called on to perform they must work as if they just came out of the box. LM76’s Pegasus Series 1 Linear Bearings feature Silicon Nitride (SiNi) Ceramic Balls in a shell with retainer and end caps all made from 440 Stainless Steel and then ArmorloyTM coated.

Motion Control – Case Study – Ball Screws used in Wearable Pumps!

Motion Control – Case Study: Wearable Pumps!

motion control ball screw application

 


motion control miniature ball screwsThe Next Generation of Intelligent Balloon Catheters Depend on Novel Designs of Ball Screw Driven Pumps

Woburn, MA –Motion Control Components Ball Screws – Case Study –

Situation:

In the realm of cardiovascular assist devices, recent developments have focused on fully implantable pumps. Among the first was HeartMate, quickly followed by Impella and HeartWare. Fully implantable devices are very expensive to develop and produce. Plus they are limited to patients who can tolerate the highly invasive procedure.

A key development in cardiovascular assist devices would be to combine the less-invasive approach of implantable balloons and external pumps with the high portability and reliability of fully implantable systems. This advance would allow the treatment of a much wider range of patients and conditions. A Steinmeyer customer set out to develop an innovative pump to achieve this advance in an intra-aortic system

 

Challenge:

One of the main technical challenges to this approach is designing a wearable pump that can carefully control the balloon’s pressurization. The pump must meet a demanding combination of performance requirements, including:

  • Precise control of pressure
  • Reversible pressurization
  • Light weight
  • Compact size
  • Quiet operation
  • Continuous performance for at least one year

Meeting these requirements was a significant challenge for their engineers. They built and tested early prototypes using traditional designs such as diaphragm pumps. But this approach required separate chambers for positive and negative pressure. The resulting systems were far too large and heavy. So they were forced to find a new approach.

motion control ball screw medical application

Results:

Their main innovation was selecting a precision ground ball screw as the drive mechanism and pairing it with a custom engineered metal bellows as the pressure chamber. Ball screws deliver exceptional thrust density while enabling high linear acceleration in both the forward and reverse directions. Surrounded by the bellows, this results in an extremely compact and quiet design. Ball screws are also known for their high efficiency (>90%), smooth operation, and long life. Their efficiency enables the use of small motors and low power consumption, which in turn reduce the size and weight of the entire system.

The engineers turned to Steinmeyer to ensure the smoothest running, highest quality ball screw. And they also knew that Steinmeyer was extremely well-qualified to provide technical support through all stages of development. Their system is meeting all of its design requirements and will soon enter late stage clinical trials.

Future:

There is an emerging trend in the development of balloon catheters to serve cardiovascular applications. Intelligent balloon catheters may one day be key to innovation. These devices will use flexible sensors and electronics along the catheter for data collection and therapeutics. They will also incorporate balloons to apply mechanical force in the heart and arteries. Ball screw driven pumps will support these future systems as well.

motion control - maxon motorMaxon A-max 16 brushed DC motor – This drive with a diameter of 16 millimeters (precious metal brushes, 2 Watt) was developed for use with an eccentric weight and a specified bearing.
automation motion control - brushed motors

Fall River, MA — Automation Motion Control – Application – Driver assist systems can help save lives by alerting driver of potential danger!The majority of traffic accidents are caused by human error. In the future, computer-controlled cars will significantly reduce the number of such accidents. Driver assist systems, such as adaptive cruise control (ACC), brake assist systems, or lane departure warning systems (LDW), can save lives. Lane departure warning systems warn the driver if the vehicle is drifting out of its lane. The LDW determines the vehicle’s position in the lane with the use of various optical sensor systems and computers. If the car is in danger of drifting out of the lane, the system activates an electric motor in the steering wheel that causes the wheel to vibrate, warning the driver.

A luxury car manufacturer has engaged maxon to supply the motors for this application. The base DC brushed motor is maxon’s A-max 16 (precious metal brushes, 2 W), modified for the application with an eccentric weight and a specified bearing. In order to prevent the other vehicle systems from being affected by the electromagnetic fields of the motor, it has been equipped with special EMI suppression for automotive applications. The small drive system must meet specific requirements: It needs to be low-noise, dynamic, feature high power density, and fit in a narrow space – requirements that maxon’s small A-max 16 easily masters..

How Would You Position Components Of An Experimental Reactor Vessel Weighing 33 Tons?

Motion Control – Application

Easily …   … Using Custom made LM76 Jet Rail Bearings and Shafting!

When a privately funded research company was ready to move from their original Proof of Concept to a sustainable fusion reactor to produce clean sustainable energy, they realized that extremely heavy components would need to be assembled and disassembled and reassembled again for design modifications and maintenance. The completed assembly would be the length of two buses and easy alignment of the individual components would be critical.

 

The main reactor, the fusion containment chamber that is capable of containing a plasma medium of 10 to 15 million degrees is made of non-magnetic stainless steel as are many of the components. The Plasma Medium could be described as a football shaped blob about 1 meter in diameter by 2 meters long. The plasma medium is injected from each end of the reactor assembly by Plasma Guns.

In addition to supporting the weight of the components, the bearings selected to move these massive loads during the construction and testing of the fusion reactor would have to be non-magnetic. Working with engineers, LM76 developed a custom 3 inch Jet Rail Bearing designed to carry both the weight of the fusion reactor and the high energy particle generators. In addition LM76 supplied precision ground, 3 inch 303 stainless steel (non-magnetic) shafting.

The custom manufactured Jet Rail Roller Blocks and 303 stainless steel shafting simplified the assembly/disassembly of the fusion containment chamber and components while ensuring critical alignment throughout travel.

This breakthrough fusion reactor is still in the experimental stage. A commercially viable reactor would need to contain 100 million degrees. Why is the project so important? Because in addition to producing sustainable energy, its only by-product is, environmentally safe, “helium ash.”.

The Engineering Edge – Application – Trunnion Grinding Slide for Oil Field

 

We are shipping another slide today for the oil patch. When Weir Oil and Gas called with a slide application that required special engineering, LM76 was all ears – as it was right up our alley. This slide is a Trunnion Grinding Slide which has a 56HP motor running at 3500 RPM mounted to the Y Axis – with a 12″ grinding wheel attached. The X Axis (52″ Stroke) runs on 440C stainless linear ball bearings that have special beryllium copper scraper seal cartridges while the Y Axis (4″ Stroke) employs profile rail guides with double scraper seal kits. Our customer did not want protective bellows so we had to ensure grinding debris would not cause bearing or screw/nut failures. On both axis, we employed our proprietary “Polymatrix, Double Preloaded Nuts” as opposed to recirculating ball nuts. Why LM76? Good question…we were the only company that got back to them with a thoughtful solution.

Wherever it is too dangerous for humans. Robots that can look for survivors after an explosion, an earthquake or other natural disasters, providing humans with a view of inaccessible areas. Powerful EC motors from maxon motor give the Japanese rescue robot “Quince” its drive.motion control application robot Quince

 

Maxon Logo

Fall River, MA — Motion Control Components Application – Robots that are used in disaster areas have to have a very high level of adaptability. They have to be fairly small, not too heavy and maneuverable enough to get through cracks or narrow spaces to reach areas deep inside a building. Furthermore rough terrain should present no problem. These rescue robots enter and explore buildings to determine if there are gases, radiation or other life-threatening hazards, before human rescue teams can search the area. Quince has proven that it fulfills all these demands. After the severe earthquake in Japan and the subsequent nuclear disaster in Fukushima, Quince managed to reach the upper floors of the ruins of the power plant in June 2011. There it measured the radioactivity levels and sent HD images to the world outside (To see video – CLICK HERE). The robot was able to supply valuable information from areas where no human can set foot.motion control robot goes down stairs

Quince weighs 27 kg and is equipped with four moving caterpillar drives (flippers). These flippers automatically adapt their angular position to the surface underneath – regardless of whether the robot is climbing steep stairs or crossing rough terrain. Correct ground contact is a very important prerequisite. This contact is accurately analyzed by measuring the power consumption of the flipper motors. Furthermore PSD (Position-Sensitive Device) sensors on the front and rear flippers measure the distance to the ground. In addition to a gripper arm (see fig. 2), two laser scanners can also be attached to the robot. These scanners are capable of accurately capturing the structure of the terrain.motion control robot navigates rough terrain

Additionally Quince is equipped with a “bird’s eye camera” and can travel quite fast, at 1.6 meters per second. The operator that controls the robot has to tell it which direction to take, but the robot itself determines the optimal flipper positions for crossing various surfaces, for example stairs. Newer Quince motors have additionally been equipped with a device for collecting radio-active dust or ultra-fine particles, as well as a 3D scanner. To ensure that no robot is lost, a connection to a wireless network is possible, which is the only way to navigate the robot if the connection cable breaks.

The rescue robot was developed by Eiji Koyanagi, Vice-Director of the Chiba Institute of Technology Future Robotics Technology Center (fuRO). Koyanagi started his career as a teacher – at the age of 51, he became a professor. This means that he has a completely different background than other researchers in the field of robotics. Quince has been specially designed for extreme conditions in environments where it would be too dangerous for humans. Therefore its main area of application is disaster areas. “When you develop a robot, you first have to consider the tasks that it will perform later. That is the biggest challenge,” explains Koyanagi. Hitherto eight Quince robots have been built. But before this could be done, all components had to be 100% functional. To this end, various trials were run in the large “Disaster City” training area in College Station, Texas. Quince was the only robot that successfully completed the entire obstacle course at the site as part of a RoboCup contest. In preparation for using the robot inside the Fukushima Daiichi nuclear power plant, several specific customizations were required. “The conditions in the nuclear reactor buildings are very tough. If we had attempted to send Quince in without modifications, it would probably have met its end,” says Koyanagi. Therefore the robot had to be able to survive a fall from approx. 2 m high unscathed, and had to be largely maintenance-free.

Powerful motors to beat every obstacle

Motion Control -Maxon Motors used in robot Quince

Where the motor selection was concerned, fuRO required absolutely reliable drives. The motors have to provide high power and high efficiency, yet be small and light. These requirements were precisely met by maxon motors, explains Koyanagi. Six powerful maxon motors drive the robot. The brushless EC-4pole 30 direct current motors each provide 200 W; two of these have been installed in the two main chains. The powerful 4-pole units give their all when Quince maneuvers its way across uneven terrain. Four additional motors (EC22) drive the moving chain drives (flippers). These can automatically adapt their angular position to the surface below. The 3D scanner unit of Quince is moved to the right position by an RE-max 24. Thanks to the special winding technology and the 4-pole magnets, the maxon EC-4pole drives are unbeatable when it comes to delivering the highest driving power per unit of volume and weight. The motors have no cogging torque, high efficiency, and excellent control dynamics. The metal housing additionally ensures good heat dissipation and mechanical stability. All motors of the chain drives have been combined with the GP32HP (High Power) planetary gearhead with MR encoder. This gearhead was customized by installing a large ball bearing and a reinforced motor shaft. With this power pack, Quince has no trouble managing almost any obstacle.

Motion Control Application- Intra-aortic pump powered by miniature brushless DC motors provides heart failure patients an aid to help hearts rest and heal!

The Maxon EC 6 motor brushless DC motor is the second smallest drive in the maxon family.

Maxon motion control application - Inter-aortic heart Pump

 

Maxon Logo

Fall River, MA — Motion Control Components Application – Chronic heart failure patients draw hope from a new technology. A team of life science entrepreneurs in Houston, Texas has developed the first catheter-deployed circulatory assist device intended for long-term use. Procyrion, Inc.’s Aortix™ provides a minimally invasive treatment option for the more than two million chronic heart failure patients in the USA alone who are too sick for medication. This pre-clinical cardiologist tool dramatically reduces risks associated with circulatory support devices and enables treatment of younger, healthier patients before progressive damage occurs

Assisting the natural function of the heart, the intra-aortic pump has been thoughtfully designed as an alternative to large, cumbersome surgical devices currently providing full circulatory support. Unlike these devices, Aortix provides minimal procedural risk. Measuring approximately 6 mm in diameter and 6.5 cm long, a cardiologist can deliver Aortix via a catheter in the femoral artery to the descending thoracic aorta. Once the catheter sheath is retracted, the self-expanding nickel-titanium anchors deploy to affix the pump to the aortic wall.

Aortix accelerates a portion of the body’s native blood flow within the pump and pushes it through fluid entrainment ports directed downstream. The jets entrain native aortic flow, transferring energy to the cardiovascular system and increasing blood flow to vital organs such as the kidneys. Additionally, in a model of chronic heart failure, Aortix decreased energy consumption of the heart by 39 percent, allowing the heart to operate more efficiently, encouraging cardiac rehabilitation and recovery.

Maxon motion control application - Inter-aortic heart Pump

Procyrion has been working with maxon for almost two years to develop a motor for this unique and demanding application. The basis for the Aortix device is a maxon EC6 motor with some customization including the electrical lead, shaft length, and bearing assemblies – all designed to make the pump durable and biocompatible. maxon also designed a high efficiency motor core for this application, which extends battery life and produces less heat so it doesn’t adversely affect the circulating blood. In addition, maxon is working closely with Procyrion to implement a magnetic torque drive, so the motor could be mounted inside a hermetically sealed chamber. This configuration eliminates the possibility of blood entering the motor core. The magnetically coupled pump arrangement is a method sometimes used for giant pumps in the oil field, but because of maxon’s breadth of experience across multiple industries, the company was able to help the Procyrion team successfully transfer this technology to a miniature scale medical application.

Each Aortix device consists of a small, continuous flow pump mounted within a self-expanding anchoring system. The anchored pump attaches to a flexible power lead, which can be tunneled to a desired transdermal exit site or to a Transcutaneous Energy Transfer (TET) system for subcutaneous implantation without an indwelling power lead.

Maxon motion control application - Inter-aortic heart Pump

Presently, the device can operate for over eight hours on a single battery pack. The external battery pack and control unit have been designed to be “hot swappable”, meaning the battery can be changed without needing to stop the device. A variety of charging devices can be used.

“Aortix reduces the heart’s energy consumption by 39 percent.”

The Procyrion team has also built a TET charging system that enables the battery to be charged wirelessly. This design has the potential to significantly reduce the risk of infection, common with other implantable heart pumps.

Maxon motion control application - Inter-aortic heart Pump

Because traditional assist devices replace heart function rather than support it, device failure can be fatal. With Aortix, a partial support device which doesn’t obstruct native blood flow, failure is not life threatening. Should the pump fail, the device can easily be retrieved and replaced in another minimally invasive, catheter-based procedure.

Motion Control Application – Universal XYZ Robot for Microscopy and Pipetting from Intellidrives!

Motion Control Component - Pipetting Robot

 

 

Motion Control Components - Intellidrives-Logo

 

Philadelphia, PA, – Motion Control Components and Systems – Manual pipetting is a time-consuming process that can lead to repetitive stress injuries. Automatic pipetting involves the use of robots to perform this type of tedious bench work, allowing scientists more time to design experiments and analyze data.

Overview

“Pipetting” refers to the use of pipettes, which are laboratory tools commonly used in biology and chemistry. They’re generally used to dispense a measured volume of liquid, although a pipette’s specific design can vary considerably from single pieces made of glass to complex devices that use electronics. Many types of pipettes draw up the liquid by creating a partial vacuum above the chamber that holds the liquid. A pipette’s accuracy and precision primarily depends on its design.

Intellidrives Motion Control Component - Pipetting Robot

Automatic Pipetting

Manual pipetting is often complex and inefficient, leading to increased preparation time, training requirements and operational costs. This process also increases the chances of procedural errors in an experiment.

An automated pipetting system generally transfers liquids between pre-selected containers in a programmed sequence. They’re also known as liquid-handling robots, especially when they include other components such as laboratory shakers and microplate washers in addition to pipettes. The ability to increase throughput and reproducibility is one of the primary advantages of liquid-handling robots.

These robots dispense liquids into containers such as tubes and wells. They’re often integrated into other systems such as liquid chromatographic systems, typically as automated injection modules. In addition to saving valuable time for scientists, liquid-handling robots are especially useful for preparing samples more precisely in applications requiring high-throughput in complex sequences. They may also be used for weighing samples in liquid and powder form as well as performing many types of biological and chemical assays.

These systems may contain additional components for feeding samples into heating and cooling systems, typically for the purpose of thermal cycling. Their physical construction may also allow them to easily integrate into peripheral lab-ware. For example, a liquid handler can be fitted with robotic arms that the user can program to manipulate external lab-ware, further enhancing the robot’s uses. Other features of automated liquid-handling robots include start/stop functions and the ability to coordinate the steps in a sequence, which is especially useful when performing assays.

Pipetting Robots Confirgurations

XYZ robots are automated liquid-handling platforms that provide a range of solutions for preparing samples. They provide a common platform that allows scientists to easily share protocols and reproduce results. These robots automate experiments that scientists would otherwise need to perform manually, allowing them more time to answer important questions.

IntelLiDrives XYZ robots support interfaces to external I/O devices such as fluid pumps. An adaptor is also available for the XYZ robot that allows it to hold a Society for Biomolecular Screening (SBS)-standard multi-well plate. This system allows the user to perform pipetting applications such as automated microscopy with a high degree of resolution and repeatability.

The user can also change the placement and orientation of individual devices to provide a variety of configurations, and one stage can even be removed entirely to create an XY setup.

Robot Programming

Users programs pipetting sequences, using GUI (graphical user interface) with icon-based programming or writing sequence scripts with a VB-like language. No programming experience required to create complex pipetting sequences with interfaces to external pumps and other labware hardware.

Application – Rotary Table from Intellidrives Tackles Big Wafers!

INTELLIDRIVES’s Direct drive rotary servo tables.

Intellidrives Motion Control Component - Rotary Table for Big Wafers

Philadelphia, PA, — Motion Control Components and Systems – The ACR-335UT direct drive rotary table from IntelLiDrives adapts linear motor technology, coupled with precision bearings, to provide faster and more accurate handling of the 300 mm semiconductor wafers.

The 335 mm diameter center opening in the ACR-335UT rotary table easily accommodates large 300 mm (12 inch) semiconductor wafers, allowing for extraction of the chip dies from the wafer during semiconductor assembly manufacturing processes or dual side wafer inspection.

Presently, semiconductor assembly equipment manufacturers do only limited wafer rotation, but ACR-335UT stage goes 360°, at up to 300 rpm speed.

This large angle wafer rotation can be done without need to align wafer carrier before placement on the table, thereby increasing throughput. An XY table that carries the rotary table is used for linear Cartesian Alignment. The large open center allows equipment above and below the table to extract precut integrated circuit dies cut from the 300 mm wafer or to do dual side wafer measurement and inspection.

Today’s mechanical drive technologies used in processing 200 mm (8 inch wafers) such as gear drive, worm drive and belt all lack positioning stiffness and accuracy. While worm gear rotary tables can fully rotate wafer , it speed is in single digit rpm. Belt drives can rotate at high speeds, but low belt stiffness and high drive inertia results is low accuracy and poor dynamics.

While these characteristics could be tolerated in the past, since it was not until advent of the large semiconductor wafers that a high accurate, precise and large open aperture rotary actuator was needed.

The ACR-335UT rotary table is essentially a linear motor “curved” to form a ring. There are 16 RotoLinear motoring modules (up 24 modules can be installed for higher torque capability) within the ring that forms the motor. Axial placement of these modules along with the ultra-thin bearing system allowed design of the very low profile rotary stage.

The positioning stiffness of the direct drive ACR-350UT rotary table allows it to achieve and to maintain arc-sec accuracy at hundreds of rpm and excellent dynamics even during fast Cartesian (XY) wafer indexing.

Also vital, and the major manufacturing challenges, were the tight tolerances on the axial and radial bearings that allowed to achieve both axial and radial run-outs well under 10 microns.

AccuRing rotary tables provide superior angular positioning and are designed to eliminate backlash, friction and wear problems associated with worm, gear and belt drives. Low maintenance and high throughput characteristics of the AccuRing stage yields the lowest total cost of ownership.

Compact package and Superior design of the AccuRing rotary stages was optimized to minimize stage height. The low profile of the stage reduces total system working height. Angular contact bearings are used to maximize performance with respect to wobble, moment stiffness and friction. AccuRing stage has large clear center aperture that can be used for air or wire line feed-through or beam delivery.

AccuRing utilizes direct drive three phase planar brushless motor technology. There are no brushes to replace and no gear trains or belts to maintain. Coreless magnetic design assures smooth rotation and dynamic performance.

Accurate Positioning is assured with contact-less encoder. The motor and rotary encoders are directly coupled to eliminate coupling backlash. The low inertia and zero backlash make AccuRing the ideal solution for applications requiring frequent directional changes.

Motion Control Application- Maxon Drives Help People Walk Again!

At the first Cybathlon in Zürich, researchers are presenting the world’s best exoskeletons – devices that enable paraplegics to walk again. Motors from Switzerland play a central part in this development.

Maxon motion control application - Helping People Walk Again

Fall River, MA — Motion Control Components Application – On October 8th 2016, people with paraplegia are going on a footrace at the Cybathlon in Zürich. Aided by exoskeletons, they will compete against each other on an obstacle course to show the public how far advanced technology has come in this area.

Switzerland, is playing a central role in this process. Many of the exoskeletons are fitted with components from the canton of Obwalden – components without which there wouldn’t be a lot of movement to be observed.

From the planet Mars to an exoskeleton

Robotic suits have to be both powerful and lightweight. Too much weight would cause the battery to drain in no time. This presents a big challenge to developers. Most of the motors that are strong enough to power an exoskeleton are large and heavy. This is why engineers are turning to the Swiss company that already developed the drives for NASA’s Mars rovers: maxon motor. maxon drives are powerful, lightweight, and energy-efficient, meaning that they can conserve battery power, and be very durable.

“We spent decades perfecting our motors”, says maxon CEO Eugen Elmiger. A lot of money has gone into research and development. It was worth it: These days, the motors from Switzerland can be found everywhere, in robots, airplanes, cars, and medical devices.

Knowledge yields an advantage in the market

Providing competent technical support for customers is just as important as delivering high-quality products. Small businesses and start-ups often approach maxon with specific drive technology problems that they lack the expert knowledge to solve by themselves. maxon motor, in turn is able to help with its extensive experience in the field, a strength that lets the company stand out from the international competition. “Our knowledge and the ability to give expert advice are a great advantage in the market,” says Elmiger. The Cybathlon is a good example: In the field of exoskeletons, the Swiss company has a pretty clear idea about what’s important besides choosing the right motor. As a result, quite a few of the participating teams are using products from Switzerland. The same is true for other disciplines, such as prosthetic arms or legs and electrical wheelchairs.

maxon supports the Cybathlon as a sponsor and partner

The Cybathlon games are organized by the ETH Zürich and are being held for the first time on October 8, 2016 at the Swiss Arena in Zürich. Around 80 teams from all over the world will be participating. The machine-assisted competitors will compete against one another in six disciplines: prosthetic legs, prosthetic arms, exoskeletons, motorized wheelchairs, bicycles with muscle stimulation, and virtual racing using thought control. What’s not allowed at the Paralympics is an absolute must at the Cybathlon: the use of state-of-the-art technology. “Our aim with the Cybathlon is to break down barriers between the general public, people with disabilities, and scientists,” says ETH professor Robert Riener, who invented the Cybathlon.

The Swiss drive specialist maxon motor supports the Cybathlon as a sponsor and partner. The company will be present at the games with a workshop for the teams and a small exhibition about the history of prosthetics.
