Delivering high-torque output for heavy-duty industrial positioning, the Mitsubishi Electric HG-SR702BJ serves as a key actuator in the HG-SR Series of high-inertia rotary servo motors. Designed for demanding applications requiring stable speed control and robust holding torque, this 7.0 kW AC servo motor features an integrated electromagnetic safety brake and a specialized protective oil seal to ensure longevity in challenging environments. The high-inertia rotor design optimizes stability when driving load mechanisms with fluctuating or high inertia ratios, preventing mechanical resonance and maintaining dynamic path accuracy.

The HG-SR702BJ is designed for seamless matching with the MR-J4-700A, MR-J4-700B, and MR-J4-700GF series servo amplifiers. When upgrading from legacy HC-SFS or HA-LFS series motors, evaluate the structural shaft dimensions and verify mounting hole compatibility, as physical frame alignments vary between older generations and the HG-SR series.
Due to the motor's substantial 7.0 kW power and high-inertia load capacity, dynamic deceleration phases generate significant regenerative energy. System designers must size and integrate appropriate external regenerative brake options (such as MR-RB50 or MR-RB137) based on duty cycles to prevent overvoltage faults (AL 30 or AL 33) on the matching servo drive. Additionally, the electromagnetic brake (B suffix) must never be used for dynamic braking or active deceleration; it is strictly rated as a static holding brake.
Always ensure that the MS connection plugs for power, brake, and encoder are fully sealed and strain-relieved. If mounting the motor vertically with the shaft facing upward, design a drip loop in the cabling to prevent moisture or oil runoff from directly pooling on the MS connectors. Do not run the oil seal dry; ensure a light coating of gearbox lubricant is present at the shaft-seal interface to avoid premature seal failure and thermal degradation.
Verify the mechanical alignment of the coupling between the motor shaft and the machine load. Misalignment beyond specified tolerances will induce rapid wear of the internal bearings and oil seal.
Route the encoder cable separately from the 3-phase power and electromagnetic brake lines. Maintain a minimum distance of 30 cm to mitigate high-frequency electromagnetic interference (EMI).
Securely ground the motor housing to the machine frame using a dedicated ground wire connected to the amplifier's protective earth (PE) terminal.
