Description
Operating within heavy industrial motion architectures, the Mitsubishi Electric HG-SR152J provides precision rotary drive capability as a medium-inertia AC servo motor. Engineered for high-duty cycling and dynamic stability, this motor features a nominal output rating of 1.5 kW and a rated speed of 2000 RPM, making it exceptionally suited for modern automated systems. The integrated oil seal ensures a reliable barrier against liquid contamination in harsh factory floor environments, while the Class 155 (F) insulation rating guarantees thermal resilience under sustained peak currents of up to 9.4 A.
Key Features
-
High-Torque Performance: Provides dynamic peak capability with a maximum output torque of 21.5 Nm.
-
Robust Environmental Protection: J-suffix configuration indicates an integrated shaft oil seal for reliable deployment in industrial oil mist environments.
-

Empirical Engineering Insights
Alternative Models & Compatibility
The HG-SR152J direct-drive AC servo motor acts as an upgraded functional alternative to older legacy HC-SFS152 motor systems. When planning retrofits, ensure the associated servo amplifier parameters are updated. Note that while mount dimensions are standardized, cable connectors and encoder signals may require interface adapters if migrating from older MELSERVO generations.
Application Pitfalls & Engineering Notes
Operating the HG-SR152J close to its physical limit of 21.5 Nm peak torque for extended periods can trigger overcurrent or overload faults (such as AL.50 or AL.51) on the matching MELSERVO drive. In systems with vertical or high-inertia loads, integrate a dynamic regenerative braking resistor to prevent overvoltage faults on the DC bus during decelerating cycles.
Commissioning & Wiring Tips
To eliminate electromagnetic interference (EMI) issues, route the motor’s heavy U/V/W power cables and the sensitive feedback encoder cabling through separate grounded metallic conduits. Maintain a minimum routing distance of 30 cm between control signaling cables and high-power conductors. Securely connect the motor chassis grounding terminal to the central electrical cabinet ground bus bar.
Installation Guidelines
CRITICAL WARNING: ELECTRICAL SAFETY HAZARD
Before performing any installation, wiring, or maintenance tasks, isolate and lock out all AC input power to the matching servo amplifier. Verify that the DC bus capacitor voltage indicators on the drive have fully extinguished (allow at least 15 minutes of discharge time) to mitigate residual electrical shock hazards.
1
Mount the AC servo motor securely to a rigid, vibration-damping machine frame or base using high-tensile mounting bolts tightened to the OEM specified torque.
2
Align the motor shaft precisely with the driven load shaft using a flexible coupling. Misalignment exceeding technical limits will lead to premature bearing failure and oil seal degradation.
3
Plug in the motor power (U, V, W, PE) and encoder feedback connectors, ensuring that the seal rings are seated perfectly to prevent moisture or oil entry. Do not subject the connectors to excessive structural tension.
