Mitsubishi Low-Inertia, Small-Capacity Servo Motor HG-MR053B

The HG-MR053B is part of Mitsubishi’s low-inertia, small-capacity servo motor series, designed for applications requiring fast response, precise motion control, and compact installation.

Key Specifications:

●Rated Output: 0.05 kW

●Rated Speed: 3000 r/min

●Maximum Speed: 6000 r/min

●Power Supply: 200 V

●Electromagnetic Brake: Included

Performance Features:

1. High Torque in High-Speed Range – The motor delivers up to 350% of rated torque at higher speeds, enabling dynamic acceleration and stable operation in demanding speed zones. This high-torque performance is specifically supported when paired with the HG-KR series servo amplifiers.

2. High-Resolution Absolute Position Encoder – Equipped with a standard high-resolution absolute encoder offering 4,194,304 pulses per revolution (22-bit). This ensures exceptional positioning accuracy, enhances stopping precision, and supports reliable absolute positioning without the need for a homing routine after power-up.

3. Enhanced Environmental Resistance – The motor complies with IP65 protection standards (across the HG-KR, HG-MR, HG-RR, and HG-UR series), providing robust resistance against dust and water ingress. This makes it suitable for use in challenging industrial environments.

Typical Applications:

Thanks to its low inertia and high responsiveness, the HG-MR053B is ideal for precision automation tasks such as small assembly robots, packaging equipment, indexing systems, and other applications requiring rapid start-stop cycles and accurate positioning.

Compatibility Note:

For full utilization of its high-torque capabilities at elevated speeds, the motor must be used in combination with Mitsubishi’s HG-KR series servo drives.
