Details

Compact mini servo motors are built for low-speed, high-precision motion where smooth, stable operation matters.

An integrated drive design combines an outer-rotor structure, quality bearings, and accurate current sensing for controlled torque output.

RS485 communication and onboard control electronics support speed/position commands with encoder feedback for closed-loop motion control.

Wiring stays straightforward with a labeled CAN/RS485 port, ID switch for bus setup, and clear pin definitions for power and signal.

PC-based tools enable parameter tuning, testing, and firmware updates, with multiple control modes available for different motion tasks.
