Product Description

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.

FAQ

What does the 'B' suffix indicate in the HG-SR502B model number?

The 'B' suffix indicates that the motor is equipped with an integrated electromagnetic holding brake, which is rated for a static friction torque of 44 Nm.

Can the electromagnetic brake on the HG-SR502B be used to stop a moving motor?

No. The built-in brake is designed exclusively for position holding during power-off or stopped states. Using it to stop a rotating motor will damage the brake mechanism.

What is the rated speed and power output of the HG-SR502B?

The motor has a rated output of 5.0 kW at a rated speed of 2000 r/min, with a maximum allowable speed of 3000 r/min.

What is the environmental protection rating of this servo motor?

The motor housing is IP67 rated, excluding the shaft penetration area, making it highly resistant to dust and water ingress.
