Mitsubishi Electric HG-MR053B HG-MR Series Rotary Servo Motor

Description

Engineered for high-speed, high-precision positioning applications, the HG-MR053B is an ultra-low inertia, small-capacity rotary servo motor designed by Mitsubishi Electric for integration with the MELSERVO-J4 series. This high-performance motor features an integrated electromagnetic safety brake, making it suitable for vertical axis applications or systems requiring a secure holding torque when the control power is removed.

The HG-MR053B utilizes a high-resolution absolute encoder to deliver exceptional positioning accuracy and minimal velocity ripple. Its compact frame footprint and low inertia rotor allow for rapid acceleration and deceleration cycles, optimizing throughput in dynamic manufacturing lines and automated assembly systems.

Features

• Ultra-low rotor inertia optimized for highly dynamic start-stop operations.
• Integrated electromagnetic holding brake for load securing during power-off states.
• High-resolution absolute/incremental encoder for precise speed and position control.
• Compact physical dimensions allowing integration into space-constrained machine layouts.
• Seamless compatibility with MELSERVO-J4 series servo amplifiers.

Applications

• Semiconductor fabrication equipment and wafer handling systems.
• Pick-and-place assembly machines.
• Precision XY positioning tables and laboratory automation.
• Packaging machines and small-scale material handling systems.
• In-circuit testers and electronic component insertion machinery.

Installation Guidelines

Ensure the servo motor shaft is aligned precisely with the driven load; misalignments exceeding specified radial or axial load limits will lead to premature bearing failure. The integrated electromagnetic brake is designed strictly for holding a stationary load and must not be used for dynamic braking operations.

When routing the motor and encoder cables, maintain separation from high-voltage power lines to prevent electromagnetic interference. Connect the protective earth (PE) terminal securely to the main cabinet ground plane. Ensure ambient operating temperatures remain within the range of 0 to 40 degC, with a non-condensing relative humidity below 80%.
