Description

Delivering robust dynamic performance in demanding industrial motion control systems, the Mitsubishi Electric HG-SR352BJ functions as a high-capacity rotary servo motor within the HG-SR Series. Engineered with a 3.5 kW rated output and a rated speed of 2000 r/min, this medium-inertia unit features an integrated electromagnetic brake and oil seal to guarantee positioning retention and environmental protection during vertical axis or high-load operations.

Key Features

  • High-Resolution Feedback: Equipped with a high-resolution absolute encoder for micro-positioning precision and motion smoothness.
  • Electromagnetic Holding Brake: Built-in safety brake prevents axis dropping during power-off states or emergency stops.
  • Enhanced Environmental Seal: Integrated oil seal allows direct coupling to gearboxes and protection in harsh environments.
  • Optimized Inertia Design: Medium-inertia rotor design provides excellent control stability under fluctuating load conditions.

Applications

  • Material Handling Systems: Conveyors, automated transfer lines, and heavy-duty gantry axes.
  • Metalworking & Machining: Feeding axes for machine tools requiring high torque stability.
  • Packaging & Printing Machinery: High-speed tension control and multi-axis synchronized drive systems.

Empirical Engineering Insights

Alternative Models & Compatibility

The HG-SR352BJ is fully matched with the Mitsubishi MELSERVO-J4 amplifier range, specifically the MR-J4-350A and MR-J4-350B drive modules. When upgrading from legacy HC-SFS series models (such as the HC-SFS352B), verify mounting depth adjustments and encoder adapter cable configurations, as physical connector interfaces have changed.

Application Pitfalls & Engineering Notes

Always ensure that the electromagnetic brake is used strictly for holding and not dynamic braking. Attempting to use the brake to decelerate a moving load will result in premature wear of the internal friction plates and eventual positioning failure. Additionally, ensure the oil seal is regularly inspected in environments where high-temperature gear fluid accumulates near the shaft flange.

Commissioning & Wiring Tips

Due to the high-frequency switching cycles of the MR-J4 amplifier, the motor power cable and the encoder cable must run through separate shielded conduits to prevent signal corruption. Always ground the motor frame directly to the common cabinet backplate using a low-impedance grounding strap to prevent ground loop currents from interfering with the absolute encoder feedback.

Installation Guidelines

CRITICAL WARNING

Ensure all AC main power lines feeding the servo amplifier are disconnected and locked out prior to physical installation. Allow the amplifier's internal bus capacitors to discharge fully (verify voltage drop below 50 VDC across terminal blocks) before terminating the power or brake wiring on the HG-SR352BJ.

1

Mount the motor securely on a rigid metal foundation. Misalignment between the motor shaft and the load can damage internal bearings and cause premature oil seal failure. Use a flexible coupling.

2

Connect the encoder cable and power-with-brake connectors. Ensure the connector seals are completely seated to preserve the IP protection rating. Do not apply excessive radial or axial load to the connectors during routing.

3

Prior to starting test runs, verify brake release operation by manually supplying the nominal holding-brake voltage (24 VDC) and checking that the shaft rotates freely.

FAQ

Can the brake on the HG-SR352BJ be powered directly from the drive outputs?

No. The electromagnetic brake requires an external 24 VDC power supply. Use a dedicated surge protector or diode across the brake relay contacts to absorb voltage spikes during switching.

Which servo amplifier models are recommended for the HG-SR352BJ?

This motor is designed to work seamlessly with the Mitsubishi Electric MR-J4-350A, MR-J4-350B, or MR-J4-350W2 amplifier modules.

Does this model come equipped with an integrated oil seal?

Yes, the 'J' suffix in the model code (HG-SR352BJ) indicates that an oil seal is factory-installed on the drive shaft flange.

What is the maximum torque rating of this 3.5 kW motor?

The HG-SR352BJ delivers a peak maximum torque of 50.1 Nm to handle demanding acceleration and deceleration cycles.
