Details
MF9025v2 combines the motor and drive in a compact integrated servo package, updated with 18‑bit encoder feedback plus PWM and CAN/RS485 control options.
Multiple control modes (torque, speed, position) are supported, with CAN or RS485 communication and real‑time stator temperature monitoring for tighter control.
Performance curves compare the 16‑turn and 35‑turn winding options across speed, torque, current, power, and efficiency.
