Description

Engineered for high-inertia industrial motion control, the Mitsubishi Electric HG-SR502J delivers heavy-duty dynamic response and robust torque characteristics within the MELSERVO-J4 automation platform. This medium-inertia, high-capacity industrial AC servo motor is equipped with an integrated oil seal to safeguard internal windings and bearings from environmental ingress, making it highly suitable for demanding material handling, gantry drive, and metalworking machinery.

Key Features

High-torque capacity with a continuous power rating of 5.0 kW.
Integrated factory oil seal (designated by the J suffix) for protection against industrial lubricants.
Class 155 (F) thermal insulation class, providing enhanced resilience against thermal stresses.
Low-vibration design verified to V10 rank for smooth operation across the speed range.

Applications

Heavy gantry positioning systems and structural fabrication machinery.
Industrial metal processing, stamping presses, and CNC axis control.
High-capacity material handling conveyors and automated warehousing storage/retrieval systems.
Paper mills, printing equipment, and continuous web tension control systems.

Empirical Engineering Insights

Alternative Models & Compatibility

The HG-SR502J serves as the standard modern replacement for older HC-SFS502 series motors. When migrating from the HC-SFS series, note that parameters on the corresponding MR-J4 amplifier must be correctly selected using the MR Configurator2 software to ensure optimal loop tuning and prevent encoder communication faults.

Application Pitfalls & Engineering Notes

While the J-suffix indicates a robust factory-installed oil seal, the seal is not designed for submerged operation. In applications where the motor is mounted vertically shaft-up or shaft-down, implement physical drip loops and protective splash shields to prevent continuous pooling of lubricants or coolants against the shaft face, which can degrade the seal material over time.

Commissioning & Wiring Tips

To minimize electromagnetic interference (EMI) issues, run the power and encoder cabling through separate grounded metallic conduits. Ensure that the motor frame is grounded directly back to the common drive plate with a minimum 10 AWG protective grounding conductor. Always verify correct polarity on the thermal sensor circuit, if configured within the drive's parameter settings.

Installation Guidelines

CRITICAL WARNING: HIGH VOLTAGE AND THERMAL HAZARD

Before performing any wiring, mounting, or maintenance on this motor, ensure that the power supply to the associated servo amplifier has been disconnected for at least 15 minutes. Verify that the charge lamp on the amplifier is completely off and measure the main circuit terminal voltage to guarantee residual charge has fully dissipated.

1

Mount the motor on a rigid machine base with flat alignment surfaces to prevent structural resonance and undue mechanical load on the bearings.

2

Connect the power supply and encoder cables using certified Mitsubishi heavy-duty industrial connectors, ensuring the coupling nut is fully tightened to maintain the ingress protection rating.

3

Set the correct motor code in the amplifier settings using MR Configurator2 before performing the first test run to prevent over-speed or incorrect phase control.

FAQ

Which servo amplifier series is compatible with the HG-SR502J AC servo motor?

This motor is designed to pair directly with the MELSERVO-J4 amplifier series, specifically matching models such as the MR-J4-500A and MR-J4-500B.

What is the function of the 'J' suffix on this motor's part number?

The 'J' suffix designates the inclusion of a factory-installed oil seal, protecting the interior mechanics from splashing lubricants and industrial oils.

What are the ambient temperature operating limits for this motor?

The motor is designed to operate continuously in ambient indoor temperatures ranging from 0 to 40 degC without derating, in environments free of corrosive gas.
