What Is the Mitsubishi HG-SR102J?
When your production line demands precise motion control under harsh conditions, the Mitsubishi HG-SR102J AC servo motor delivers. This HG Series motor handles heavy loads with a nominal torque of 4.8 Nm and a peak torque of 14.3 Nm. Its 22-bit absolute encoder ensures accurate position feedback, eliminating drift over time. Built for 200VAC class systems, it integrates seamlessly into modern automation architectures.
Key Performance Metrics
Torque and Speed
The HG-SR102J provides a nominal torque of 4.8 Nm and a maximum torque of 14.3 Nm, offering ample margin for acceleration and overloads. It achieves a rated speed of 2000 RPM and a maximum speed of 3000 RPM, enabling rapid cycle times. The rated current of 5.6 A and maximum current of 17 A support these power demands efficiently.
Encoder Precision
Equipped with a 22-bit absolute encoder, this motor delivers high-resolution position feedback. This eliminates the need for homing routines after power loss, reducing downtime and improving system reliability.
Environmental Protection
With an IP67 rating, the HG-SR102J resists dust ingress and temporary water immersion. This makes it suitable for washdown environments, machining centers, and outdoor installations where contaminants are a concern.
Real-World Applications
Packaging Machinery
In high-speed packaging lines, the HG-SR102J's rapid acceleration (3000 RPM max) and precise torque control minimize product waste. The IP67 protection withstands dust and occasional washdowns, extending service life.
Material Handling
For conveyor systems and pick-and-place robots, the 980 N maximum radial load and 490 N maximum axial load handle heavy payloads without premature bearing wear. The oil seal protects internal components from lubricant contamination.
Installation Guidance
Mounting
The 130x130mm flange mounting simplifies integration into existing machine frames. Ensure the mounting surface is flat and rigid to avoid misalignment. The straight shaft (standard) couples directly to loads via a flexible coupling or keyed connection.
Wiring
Connect the motor to a compatible Mitsubishi servo drive using shielded cables to minimize electrical noise. Verify the supply voltage matches the 200VAC class requirement. The rated current of 5.6 A guides cable sizing for continuous operation.
Maintenance and Reliability
Routine Inspection
Periodically check the oil seal for leaks and the shaft for excessive play. Clean the exterior with a dry cloth; avoid high-pressure water jets near the seal. Inspect the encoder cable for damage, as signal loss can cause positioning errors.
Environmental Considerations
Operate within the IP67 rating limits: dust-tight and protected against temporary immersion. Avoid prolonged exposure to cutting fluids or corrosive chemicals that may degrade the seal over time.
Selection and Purchasing Advice
Before ordering the HG-SR102J, verify your servo drive compatibility and required feedback interface. The 22-bit absolute encoder typically works with Mitsubishi MR-J4 series drives. Confirm the mounting dimensions (130x130mm flange) and shaft type (straight) match your mechanical design. SpareTechPLC stocks this model and can assist with availability and replacement options.
