ECM has taken a significant leap by seamlessly integrating its state-of-the-art printed circuit board (PCB) stator technology into compact, powerful actuator assemblies designed specifically for robotic joint applications.
Most notably, ECM partnered with a large, multinational, high-tech precision gearing company, whose products are widely used in industrial robots, semiconductor manufacturing equipment, medical equipment, and aerospace programs to prototype one of our most impressive robotic joint actuator designs.
Benefits of PCB Stator Technology for Robotic Joint Actuator applications
ECM can integrate seamlessly into a range of robotic applications to provide compact, efficient, torque-dense solutions. Our flexible form factor and the ability to produce our motor as a thin ring allows for compact integration with a variety of torque multipliers (strain wave, planetary gear, etc.). Leveraging ECM’s technology creates motors with high power density and minimal axial length, which allows for compact, lightweight robotic designs that were previously not possible. Increased motor efficiency improves battery life for mobile applications and reduces energy costs for stationary ones. Additionally, the ease of hollow shaft designs adds to the technology’s flexibility.
“ECM’s technology simplifies the geometry of the rotor and stator, reducing the number of parts within a fully integrated actuator gear drive platform for a wide range of robotic automation applications.”Chris Fielding, ECM, Vice President of Applied Engineering
ECM provided an elegant solution without disruption or alteration of existing form factors.
ECM’s design allowed for compact integration with harmonic drive torque multipliers without compromising the design advantage of a hollow shaft. Our robotic joint actuator was more efficient at half the weight and half the axial length of a commercially available competitors’ integration.
