Mitsubishi MR-J3HC5SB-10M Direct Drive Rotary Servomotor for MELSERVO

The Mitsubishi MR-J3HC5SB-10M (MR-J3HC5SB-10M) is a high-rigidity direct drive rotary servomotor designed for high-precision motion control applications within Mitsubishi Electric MELSERVO systems. Operating as a direct drive motor, this unit eliminates the need for mechanical transmission components such as gearboxes, providing smooth rotational performance and exceptional positioning accuracy. It features a hollow flanged shaft configuration that allows cables and tubing to pass directly through the center of the motor assembly. Engineered for demanding automation tasks, the MR-J3HC5SB-10M delivers a rated power output of 1,508 W (1.508 kW), a rated operating current of 16 A, and a rated torque of 72 Nm. Feedback and thermal monitoring are handled by an integrated 20-bit absolute feedback encoder and a built-in thermistor, ensuring precise closed-loop speed and position regulation while safeguarding against thermal overload. The unit is designed with a 230 mm by 230 mm flange mounting profile and offers performance equivalent to the TM-RFM072G20 design. It is ideally suited for rotary indexing tables, precision positioning machinery, and advanced manufacturing equipment requiring high torque and rigid rotary motion.
