ECM’s ‘Eight Ball’ integrates a PrintStator-designed PCB Stator with a 50:1 harmonic drive, delivering an impressive 18.8 Nm of torque in a compact form factor.
US electric motor design software firm ECM PCB Stator Tech, has announced the launch of its new servo motor featuring an integrated 50:1 gear ratio harmonic drive - engineered to deliver unmatched torque density, precision and compactness.
ECM’s new ‘Eight Ball’ motor offering will be on display at Automate 2025 in Booth 6223, alongside the company’s lineup of 0.5Nm and 2Nm Servo Evaluation Motors.
ECM said the Eight Ball addresses critical challenges faced by automation, robotics, aerospace and medtech engineers: space constraints, weight sensitivity and precision control. Despite its form factor (2.95" x 3.35" x 1.96") and minimal weight (0.57 kg/1.26 lbs), the Eight Ball generates 18.8Nm of torque - driven by an integrated harmonic drive and powered by ECM’s patented PCB Stator motor technology.
“The Eight Ball is a breakthrough in what’s possible for compact, high-precision motion control,” said Brian Casey, CEO of ECM PCB Stator Tech. “By combining our advanced PCB Stator technology with an integrated harmonic drive, we’re empowering customers to meet - and exceed - the most demanding engineering challenges across robotics, aerospace automation, and beyond.”
Equipped with dual encoders for closed-loop feedback, ECM said the Eight Ball delivers cog-free operation with pinpoint positional accuracy - making it ideal for robotic arms, precision automation, UAV systems and medical devices where every gram and degree counts.
By uniting high-torque harmonic drive technology with ECM’s PCB Stator design approach, the Eight Ball offers:
ECM’s new Eight Ball servo joins a broader suite of next-generation electric motor development - delivered through PrintStator SaaS, off-the-shelf PCB Stator Evaluation Motors and full-service Motor Development offerings.
Alongside the Eight Ball, ECM is also showcasing its 0.5Nm and 2Nm Servo Evaluation Motors at Automate 2025 - enabling innovators to fast-track product development with highly efficient, lightweight and precision-optimized servo solutions.
