Mitsubishi Electric HG-SR52B MELSERVO-J4 Rotary Servo Motor

Description

Engineered for high-precision motion control within the MELSERVO-J4 platform, the Mitsubishi Electric HG-SR52B is a medium-inertia rotary servo motor designed to deliver reliable torque output and dynamic response. This motor operates on a 200V voltage class and is equipped with an integrated electromagnetic brake, making it highly suitable for applications requiring vertical axis control or holding torque during power-down states.

The HG-SR52B incorporates a high-resolution 22-bit absolute/incremental encoder, ensuring exceptional positioning accuracy and smooth speed regulation. It interfaces seamlessly with MR-J4 servo amplifiers supporting CC-Link IE Field, SSCNET III/H, and general-purpose pulse/analog interfaces, enabling flexible integration into standard industrial automation architectures.

Features

• High-Resolution Feedback: Equipped with a 22-bit encoder providing 4,194,304 pulses per revolution for precise position and speed control.
• Electromagnetic Brake: Features a built-in holding brake to secure loads safely when power is removed.
• Robust Protection: Totally enclosed, self-cooling structure rated at IP67 (excluding shaft-through portion) for demanding industrial environments.
• Medium Inertia Design: Ideal for applications with fluctuating load inertia ratios, supporting stable tuning up to a recommended 15:1 load-to-motor inertia ratio.
• Flexible Connectivity: Full compatibility with CC-Link IE Field network and SSCNET III/H high-speed motion networks via corresponding MR-J4 series amplifiers.

Applications

• Material handling and automated gantry systems
• Packaging, wrapping, and labeling machinery
• Textile positioning drives
• Food processing and bottling lines
• Vertical axis positioning in multi-axis CNC machines

Installation Guidelines

• Alignment and Mounting: Ensure precise coupling alignment with the driven shaft. Excess misalignment can lead to premature bearing wear or shaft breakage. Do not exceed the allowable radial load of 980 N or thrust load of 490 N.
• Environmental Protection: To maintain the IP67 protection rating, install appropriate liquid-tight connectors and ensure cables are routed with a drip loop to prevent water or oil from traveling down the cable to the motor connectors.
• Heat Dissipation: Install the motor in a well-ventilated space. Avoid direct exposure to heat-radiating elements, and ensure the surrounding air does not exceed 40 degC during continuous operation.
• Grounding and Shielding: Connect the motor's protective earth terminal securely to the cabinet ground. Use shielded power and encoder cables to minimize electromagnetic interference (EMI).
