ECM Unveils High-Torque, Ultra-Compact Servo Motor with Integrated Harmonic Drive Ahead of Automate 2025
ECM 's new servo motor delivers 18.8Nm of torque from just 0.57kg-achieving an exceptional torque-to-weight ratio in an ultra-compact footprint.
NEEDHAM, MASSACHUSETTS / ACCESS Newswire / May 6, 2025 /US electric motor design software firm ECM PCB Stator Tech , has announced the launch of its groundbreaking 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 solution will be on display at Automate 2025 (Booth 6223), alongside the company 's growing lineup of 0.5Nm and 2Nm Servo Evaluation Motors available for immediate purchase.
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.
Setting a New Standard for Compact High-Torque Motors
The Eight Ball addresses critical challenges faced by automation, robotics, aerospace, and medtech engineers: space constraints, weight sensitivity, and precision control. Despite its ultra-compact form factor (2.95" x 3.35" x 1.96") and minimal weight (0.57 kg/1.26 lbs), the Eight Ball generates an impressive 18.8Nm of torque-driven by an integrated harmonic drive and powered by ECM 's patented PCB Stator motor technology.
Equipped with dual encoders for closed-loop feedback, 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.
Innovation in Every Turn
By uniting high-torque harmonic drive technology with ECM 's award-winning PCB Stator design approach, the Eight Ball offers:
Exceptional torque-to-size performance
Energy efficiency gains through minimized inertia
Reduced raw material usage and system complexity
Flexible thru-hole design for seamless system integration
ECM 's new Eight Ball servo joins a broader suite of next-generation electric motor innovations-delivered through PrintStator SaaS , off-the-shelf PCB Stator Evaluation Motors , and full-service Motor Development offerings.
ECM also offers a wider range of PCB Stator Evaluation Motors, enabling businesses to quickly test and validate this innovative motor solution.
Servo Motors Built for the Next Generation
Alongside the Eight Ball, ECM is also showcasing its versatile 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.
This launch is supported by a technical case study, which explores the engineering challenges that high-torque, space-constrained applications face-and how ECM 's integrated harmonic drive and PCB Stator architecture overcomes them.
