Case Study

ECM establishes the value of PCB Stator Technology in next generation Medical devices

Overview

ECM’s innovative approach extends beyond mere integration; we have seamlessly incorporated our cutting-edge, quiet motor technology into various medical devices.

Recently, ECM took on the task of prototyping motors for two distinct medical applications, showcasing the versatility and adaptability of our technology. The first project involved collaborating with a medical robotics company to develop a motor that effectively actuates the elbow joint of an orthosis. Meanwhile, our collaboration with an international medical device OEM resulted in an exemplary demonstration of the advantages of incorporating ECM’s quiet motor technology into their portable oxygen concentrator.

Benefits

The planar form factor and minimal axial thickness of ECM technology allows for small, lightweight motors for portable systems.

ECM’s increased efficiency reduces energy cost and, for portable systems, extends battery life. ECM’s flexible form factor enables compact integration with a variety of torque multipliers, creating systems with high torque density. Reduced raw materials and PrintStator’s utilization of well-established PCB manufacturing processes lowers cost and environmental impact.

“ECM’s PCB stator technology can significantly improve the performance of mobile medical applications and enhance the comfort of users.”

Results

Orthotic Joint Motor

The 40W motor, which ECM designed and prototyped with PCB stator technology to actuate the elbow joint of an adult orthosis, reduced system size and increased capability. The concise combination of a harmonic drive and ECM’s axially thin motor created a low volume system with high torque density, enabling patients to lift heavier items and wear a long sleeve shirt over the brace. ECM is currently collaborating with this medical robotic company to finalize system design and further benefit the patient.

Oxygen Concentrator

ECM’s oxygen concentrator prototype reduced motor axial thickness by 60% and significantly decreased system noise. When compared to the current concentrator package, this compact solution required less raw materials, which in turn reduced manufacturing costs. ECM is currently working with this OEM to optimize the design to capitalize on ECM’s motor advantages and further improve portability, reduce noise and minimize the cost responsibility of the patient.

Next Steps

ECM is in the process of introducing its PrintStator software and PCB stator technology for a wide range of medical applications. Form factor flexibility, increased efficiency, low noise and reduced cost are just a few of the many benefits of a motor solution built with an ECM PCB stator, making PrintStator’s design capabilities valuable for almost any application.
