Mitsubishi Electric HG-SR152BJ HG-SR Series AC Servo Motor

Description

Providing precise rotary motion control in industrial automation systems, the Mitsubishi Electric HG-SR152BJ operates as a high-performance AC servo motor designed for demanding positioning and speed control applications. This medium-inertia motor delivers a rated output of 1.5 kW and a rated speed of 2000 r/min, making it highly suitable for machinery requiring stable torque output and rapid response times. Built with an integrated electromagnetic brake and a protective shaft oil seal, the HG-SR152BJ ensures reliable holding capability and superior environmental sealing in harsh industrial settings.

Features

• Electromagnetic Holding Brake: Built-in safety brake prevents axes from dropping during power loss or emergency stops.
• Shaft Oil Seal: Factory-installed oil seal protects internal motor windings from fluid ingress in wet operating conditions.
• Medium Inertia Design: Optimizes load-to-motor inertia matching for heavy duty applications.
• High Insulation Rating: Class 155 (F) insulation ensures thermal protection and longevity under continuous loading.
• Low-Vibration Execution: Rated to vibration rank V10 to minimize mechanical wear on couplings and bearings.

Applications

• Machine tool feed axes and high-torque spindles.
• Material handling systems, conveyors, and gantry systems.
• Packaging, wrapping, and labeling machinery.
• Automated assembly systems and industrial robotics.

Empirical Engineering Insights

Alternative Models & Compatibility

The "B" suffix in the model code designates the inclusion of the electromagnetic brake, and the "J" suffix indicates the integration of the shaft oil seal. When replacing a standard HG-SR152 motor (without brake or oil seal) or an HG-SR152B (with brake but without oil seal), ensure the physical shaft interface matches and that your power supply configuration accounts for the 24VDC brake control lines.

Application Pitfalls & Engineering Notes

Operating the oil seal without any lubrication at the shaft interface can cause accelerated seal wear and high friction heating. In environments where no oil splashes onto the shaft, a small amount of grease should be applied during periodic maintenance to prevent seal dry-run. Always ensure adequate ventilation around the motor frame to prevent heat accumulation, especially in continuous heavy-duty duty cycles.

Commissioning & Wiring Tips

The integrated electromagnetic brake is strictly designed to hold the shaft in position when the motor is stopped. It must never be used to slow down or stop a moving load under normal operations; always command the servo drive to bring the motor to a complete stop before engaging the holding brake. Ensure a surge absorber is installed across the brake terminal relay to prevent inductive flyback spikes from damaging control relays.
