ECM PCB Stator Tech releases compact servo motor nicknamed “Eight Ball”

May 15, 2025, Detroit, Mich. — Electric motor design and technology company ECM PCB Stator Tech has released its new high-torque, ultra-compact servo motor nicknamed the “Eight Ball”.

The motor, powered by ECM’s patented PCB Stator technology and an integrated 50:1 harmonic drive, delivers 18.8 Nm of torque from a 2.95″ x 3.35″ x 1.96″ frame, and weighs only 0.57 kg, the company reported in a press statement.

Dual encoders enable closed-loop feedback, ensuring smooth, cog-free operation and pinpoint positional accuracy.

Beyond its size and power, the Eight Ball represents a leap forward in sustainable and efficient motor design:

• Compact and Lightweight: Saves weight and simplifies integration
• Energy Efficient: Lower inertia helps reduce energy draw
• Easy to Integrate: Flexible thru-hole design fits complex assemblies
• Precision Built-In: Dual encoders ensure accurate motion feedback

The motor is built for robotics, aerospace, advanced automation, medical devices and any system where precision motion control meets space constraints.
