Greenville, DE -Motion Control Components – The AxCent™ (Axes for Centralized control schemes) product platform brings the proven and powerful performance expected of ADVANCED Motion Controls, with improvements to the design architecture that utilize years of experience in the industry and the latest advancements in modern servo system design.

As technology continues its shift from analog to digital, there is still strong demand for analog designs. The reason? Analog drives provide some attractive benefits:

  • Simplicity – It’s easy to train your people to set the correct switch and potentiometer settings.
  • Proven Track Record – AMC have been building analog drives since their inception. They have continuously improved their designs to mirror the advances in component technology.
  • Performance – When tuned to maximum performance, analog current loops can often times achieve higher bandwidth and faster response than digital current loops.

How can analog outperform digital? It all comes down to the components. In a digital system, A/D conversions and processing time can add delays ranging from 20 to 100 microseconds. This may not seem like a lot, but in the highest bandwidth systems delays of this magnitude create a sizeable phase lag.

The other driving factor is cost. Large volumes and mature designs make prices attractive for everyone (except our competitors)

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 Components – Ultra Thrust Ball Screws from Steinmeyer!

Motion Control Components - Steinmeyer Ultra Thrust Ball ScrewsWoburn, MA –Motion Control Components – In recent years, ball screws have been looked at more and more favorably as replacements for hydraulics. They offer higher efficiency and speed, and can be controlled more precisely with servo loops. And who wants to deal with the unavoidable maintenance and disposal hassle of hydraulics?

Steinmeyer has been supporting this market shift with its line of Ultra Thrust ball screws. These screws utilize larger balls to support much greater load capacities. More recently, we have introduced innovations in through-the-nut return systems to push performance even higher.

The Ultra Thrust line began with our 50×20 mm nut using 15 mm balls. Our standard nut of that size, with 9.5 mm balls, was rated at a dynamic capacity of about 120 kN (12 tons). But the Ultra Thrust version exceeded twice the capacity, reaching 262 kN. We then expanded the line to include larger nuts. Most of our Ultra Thrust screws in the field are sized at 80×20 or 63×20.

More recently we extended the line with a 100×25 mm nut, using 19 mm balls. These screws have proved themselves in the most demanding applications of injection molding.

Beyond increasing the ball diameter, Steinmeyer has designed new return systems to optimize the load capacity. Our latest innovation uses multiple through-the-nut return paths, shown in the schematic below. With this system, the screw exceeds 1,400 kN of dynamic capacity!
