Mitsubishi Electric HG-SN302J-S100 HG-SN Series Servo Motor

Description

Providing reliable dynamic positioning and precise speed control under heavy industrial loads, the Mitsubishi Electric HG-SN302J-S100 is an AC servo motor engineered for compatibility with high-performance motion control drives. This unit features a 3.0 kW rated output and operates at a rated speed of 2000 r/min, delivering high torque performance while maintaining structural stability. Equipped with an integrated oil seal (designated by the "J" suffix) and built to an IP67 protection rating, this motor is specifically sealed against dust and liquid ingress, making it suitable for rigorous industrial machinery installations.

Features

• Optimized Power Output: Delivers continuous 3.0 kW output power for high-demand rotary positioning tasks.
• Integrated Oil Seal: Factory-installed oil seal protects internal components from oil mist and lubrication splashes.
• Robust Environment Protection: Totally enclosed, natural cooling design certified to IP67 standards (excluding the shaft-through portion).
• High Thermal Limits: Built to Insulation Class 155 (F) specifications to handle operational heat dissipation.
• Low Vibration Rank: Rated at V10 vibration class to ensure minimal structural wear and high rotational accuracy.

Applications

• Material Handling: Dynamic conveyor drive synchronization, gantry loaders, and automated storage systems.
• Packaging Machinery: High-speed filling, sealing, and cartoning axes requiring rapid torque response.
• Metalworking & Press Feeds: High-precision feeding systems and ancillary machine tool axes.
• Textile Production: Tension-controlled winding, spooling, and weaving drive mechanisms.

Empirical Engineering Insights

Alternative Models & Compatibility

The HG-SN302J-S100 is designed for optimized pairing with the MR-JE-300A and MR-JE-300B servo amplifiers. When upgrading older HC-SFS series installations to the HG-SN series, verify parameters related to the incremental encoder interface, as resolution registers differ. Ensure your MR Configurator2 software is updated to support the correct electronic gear and encoder resolution parameters to avoid feedback mismatch errors.

Application Pitfalls & Engineering Notes

This model features a built-in oil seal (J-type). While this provides highly effective protection, do not install the motor in environments where the oil level rises above the oil seal lip. For horizontal configurations, design standard oil-escape mechanisms in the machine gearbox to prevent oil from pooling against the seal and eventually seeping into the stator. Because the motor relies entirely on natural cooling, do not obstruct the air path around the motor frame inside the enclosure; maintain at least 100mm of clearance from adjacent structures.

Commissioning & Wiring Tips

Always use dedicated, shielded cables for encoder feedback (MR-EKCBL) and power supply (MR-PWCNS). Ground the motor’s main protective earth (PE) terminal directly to the servo amplifier’s ground plate, using a heavy-gauge wire to prevent high-frequency noise from corrupting encoder signals, which can cause erratic rotation or speed loop instability during commissioning.
