Mitsubishi HG-RR203B Rotary AC Servo Motor with Brake for MELSERVO-JE

The Mitsubishi HG-RR203B is an industrial rotary brushless AC servo motor designed for high-performance motion control applications within the Mitsubishi MELSERVO-JE series. Engineered for precision positioning and dynamic speed regulation, this compact motor delivers a rated output of 400 W (0.4 kW) and operates on a 200 V AC supply voltage class with a rated current of 2.6 A. It produces a rated torque of 1.3 Nm at a rated operating speed of 3000 RPM. The unit features a straight shaft configuration, an integrated oil seal, and a built-in electromagnetic holding brake that provides reliable shaft retention during power-loss conditions or vertical axis operations. For precise velocity and position tracking, the motor integrates a 17-bit absolute encoder yielding 131072 pulses per revolution. Built with a 60x60 mm flange mounting dimension, the HG-RR203B has an IP65 protection rating to guard against dust ingress and low-pressure water jets, and operates reliably in ambient temperatures ranging from 0 to +40 degrees Celsius. It is commonly deployed in automated assembly machines, material handling systems, packaging equipment, and robotics.
