Mitsubishi MR-J3HC5S-2M Direct Drive Rotary Servo Motor for MELSERVO Series

The Mitsubishi MR-J3HC5S-2M (MR-J3HC5S-2M) is a high-rigidity direct drive (DD) rotary servo motor designed for high-precision industrial motion control applications. Engineered for use with Mitsubishi Electric MELSERVO MR-J3 and MELSERVO J4 series drive systems, this direct drive motor delivers accurate angular positioning and stable torque without the need for mechanical reduction mechanisms. The unit is functionally equivalent to model TMRFM012G20. Featuring a robust hollow flanged shaft design, the motor facilitates compact machine integration and cable routing through its center. For precise velocity and position monitoring, it integrates a high-resolution 20-bit absolute feedback encoder, enabling dependable closed-loop control without requiring homing routines at startup. An integrated thermistor provides real-time thermal monitoring to safeguard the motor windings against overheating during demanding duty cycles. Suitable for machine tool rotary tables, semiconductor handling equipment, robotics, and automated manufacturing systems, this servo motor ensures exceptional dynamic response, rigidity, and operational longevity.
