Engineered for high-performance industrial motion control, the Mitsubishi Electric HG-SR102BJ AC Servo Motor delivers precise torque and speed synchronization within the HG-SR Series ecosystem. This medium-inertia motor is equipped with an integrated electromagnetic brake and a factory-installed oil seal, making it highly suitable for demanding positioning tasks in automated machinery.

Key Features

Integrated electromagnetic holding brake for secure shaft locking during power-off states.
Factory-installed shaft oil seal (J-type) for enhanced protection against fluid ingress.
Class 155 (F) thermal insulation rating to withstand demanding duty cycles.
Low-vibration operation certified to Vibration Rank V10.
Medium-inertia design optimized for stable load matching and smooth acceleration.

Applications

Material handling systems and gantry positioning axes.
Packaging machinery and rotary indexing tables.
Textile processing equipment and industrial feeders.
Automated assembly lines requiring precise holding torque.

Empirical Engineering Insights

Alternative Models & Compatibility

The HG-SR102BJ directly replaces legacy HC-SFS series motors of equivalent frame sizes. However, when migrating older systems, you must update the servo amplifier parameters in MR Configurator2 to match the high-resolution encoder of the HG-SR series. Ensure your MR-J4 or MR-J5 series amplifier firmware is updated to support the HG-SR motor profile.

Application Pitfalls & Engineering Notes

The integrated electromagnetic brake is designed strictly for static holding purposes. Do not use this brake for dynamic deceleration or emergency stopping under normal operating conditions, as this will cause rapid wear of the friction plates and premature brake failure.

Commissioning & Wiring Tips

To prevent high-frequency electromagnetic interference from triggering encoder communication faults, route the encoder feedback cable separately from the main motor power and brake cables. Maintain a minimum clearance of 100 mm between power and signal runs, or use grounded metallic conduit for shielding.

Installation Guidelines

CRITICAL WARNING

Ensure all input power sources are completely de-energized and locked out before attempting installation or maintenance. Residual charge in the servo amplifier bus capacitors must be allowed to fully dissipate (verify with a multimeter) before disconnecting motor leads.

1

Mount the motor securely to a rigid, vibration-free machine base to prevent mechanical resonance.

2

Align the shaft precisely with the load coupling to prevent excessive radial or axial forces on the bearings.

3

Connect the power, encoder, and brake cables, ensuring all connector seals are fully seated to maintain environmental integrity.

FAQ

What is the purpose of the B and J suffixes in the model number?

The B suffix indicates an integrated electromagnetic holding brake, while the J suffix indicates a factory-installed shaft oil seal.

Can this motor be installed in environments with oil mist?

Yes, the integrated J-type oil seal provides protection against oil mist, but the motor should still be shielded from direct, continuous liquid exposure.

What is the thermal insulation rating of this servo motor?

It features Class 155 (F) insulation, allowing it to withstand high internal operating temperatures under nominal load conditions.

Can the electromagnetic brake be used for dynamic braking?

No, the electromagnetic brake is designed strictly for static holding. Using it for dynamic deceleration will cause rapid wear and brake failure.
