Engineered for high-performance motion control systems, the Mitsubishi Electric HF-SP121B AC Servo Motor provides medium-inertia rotation and robust dynamic response. Operating at a rated output of 1.2 kW with a synchronous speed of 1000 r/min, this industrial-grade motor features an integrated electromagnetic safety brake designed to lock mechanical loads securely in place during power loss or system shutdown. Its optimized rotor design provides a stable torque-to-inertia ratio, making it an exceptional choice for heavy industrial applications requiring precise positioning and reliable load-holding capabilities.

The HF-SP121B is designed primarily for integration with matching MR-J3-150A(1)/B(1) series servo amplifiers. When replacing older HC-SFS or HC-RFS series motors, confirm the mounting flange PCD and encoder feedback parameters in the parameters of your MR Configurator software, as gain settings will require adjustment to prevent mechanical resonance.
Always ensure that your configuration accounts for thermal radiation. The continuous torque capability of the HF-SP121B is rated based on installation on a heat-dissipating aluminum flange. Operating the motor continuously at high duty cycles in ambient temperatures exceeding 40 degC without adequate ventilation will degrade winding insulation and trigger amplifier overtemperature faults.
The built-in electromagnetic brake is dedicated strictly for holding and must not be used for deceleration. Ensure a dedicated, surge-protected 24V DC power supply is used to operate the brake, keeping its line completely separate from the encoder and motor power wiring to mitigate electromagnetic interference.
Ensure all main power and control power sources to the servo drive are completely de-energized before mounting or servicing the motor. Allow at least 15 minutes for the drive's internal bus capacitors to discharge. Verify the absence of voltage with a properly rated multimeter before making contact with terminal connections.
Flange Alignment: Align the shaft center of the servo motor with the mechanical load shaft. Misalignment exceeding specifications will lead to premature bearing failure and potential shaft damage.
Brake Control Wiring: Wire the electromagnetic brake relay circuit using the recommended surge absorber. Do not power the brake circuit using the control power supply of the servo amplifier.
Environmental Check: Secure all IP-rated connectors to prevent exposure to heavy oil mist, moisture, or metallic dust. Run cabling downward to create a drip loop near the motor connector.
