Mitsubishi Electric HG-SR502B AC Servo Motor

Description

Operating within demanding motion profiles, the Mitsubishi Electric HG-SR502B serves as a medium-inertia AC rotary servo motor optimized for precise positioning control. This motor features an integrated electromagnetic brake, making it suitable for vertical axes or applications where position retention is required during power-off states. Engineered to pair with compatible MELSERVO servo amplifiers, the unit delivers stable torque output and rapid dynamic response across its entire operational speed range. Its rugged design ensures long-term reliability in harsh industrial environments where vibration and dust exposure are common.

Features

• Integrated electromagnetic holding brake prevents backdriving or axis drop during power loss.
• Medium inertia rotor design provides stable control of systems with varying or high load-inertia ratios.
• High-resolution absolute encoder interface ensures precise feedback without requiring home-return operations.
• Optimized thermal management allowing continuous duty cycles under rated load conditions.
• IP67-rated enclosure protection (excluding the shaft-through portion) protects against dust and moisture ingress.

Applications

• Vertical axis actuators and elevation mechanisms
• Multi-axis material handling systems and robotic gantries
• Packaging, labeling, and continuous-feed machinery
• Machine tool feed systems and rotary tables
• Automated assembly lines and metal stamping presses

Installation Guidelines

• Shaft Alignment: Ensure precise alignment between the motor shaft and the driven load. Misalignment can exceed the allowable radial load of 2058 N or thrust load of 980 N, causing premature bearing wear.
• Brake Control: Use an external, dedicated power supply to control the electromagnetic brake. Do not use the brake for dynamic deceleration or stopping of the motor during normal operations; it is designed strictly for holding a stopped load.
• Environmental Limits: Mount the motor in an environment where the ambient temperature remains between 0 degC and 40 degC. Avoid installation in direct sunlight or adjacent to high-temperature heat sources.
• Cable Shielding: Route motor power cables and encoder cables through separate conduits to prevent electromagnetic interference. Ensure the motor frame is securely grounded to the protective earth (PE) terminal.
