40mm Frame AC Servo Motor System, 100W Low Inertia Series

SOYA 40mm Frame 100W High-Performance AC Servo Motor (3000 RPM, 220V)

The SOYA 40mm frame (SY-G3M-04010) is a high-performance, industrial-grade 100W rated power AC servo motor series engineered by SoyaMotor. Developed for high-speed precision motion control and ultra-reliable dynamic positioning, this compact 40mm square actuator delivers a stable 0.318N.m rated torque (0.954N.m peak torque) at a rated speed of 3,000 RPM under a standard 220V AC power input. Built upon our own factory floor utilizing an advanced 10-pole magnetic design and a fully sealed IP65 chassis enclosure, it can be equipped with a 17-bit or 23-bit high-resolution absolute encoder to eliminate positional drift entirely. This premium servo series ensures flawless closed-loop control feedback and rapid acceleration response for CNC axis control, high-speed robotic pick-and-place, semiconductor wafer positioning, and medical automation globally.

Product Description

SOYA 40mm Frame High-Performance AC Servo Motor Series

Unlock exceptional dynamic response and premier positioning accuracy with the industrial SOYA 40mm frame 100W AC servo motor series. Driven by an advanced 10-pole high-density magnetic architecture, this ultra-compact square actuator delivers 0.318 N.m of rated constant torque up to a high-speed 3000 RPM cycle. It supports high-resolution 17-bit or 23-bit absolute encoders to provide perfect real-time closed-loop position feedback under precise automation and high-dynamic manufacturing environments.

Key Performance Features

▶ Ultra-High Resolution Feedback

Compatible with 17-bit or 23-bit absolute encoders to compute exact real-time closed-loop position loops, entirely preventing steps or position loss drift.

▶ Advanced 10-Pole Design

Multi-pole inner stator design provides flawless dynamic cogging smoothness, yielding an impressive peak torque multiplying factor up to 0.954 N.m.

▶ Dynamic High-Speed Torque

Maintains rock-solid constant torque outputs across high operational velocities, providing rapid acceleration and responsive speed tracking metrics.

▶ Optional Fail-Safe Axis Brake

Supports integrated mechanical spring holding brakes to lock vertical lifting axis loads safely, ensuring zero back-driving during sudden power shutdowns.
