Mitsubishi Electric HF-SP201B HF-SP Series Medium Inertia Servo Motor

Description

Operating as a high-performance rotary drive in industrial motion control systems, the Mitsubishi Electric HF-SP201B delivers medium inertia and medium capacity execution for precise velocity and positioning tasks. This AC servo motor is equipped with an integrated electromagnetic brake, making it highly suited for vertical axis control or applications requiring reliable holding torque when de-energized. Engineered for robust industrial environments, the motor balances dynamic response times with load inertia mismatch tolerance, ensuring stable operations under varying load conditions.

Key Features

• Medium Inertia Design: Provides excellent stability for mechanical systems with fluctuating load inertia ratios.
• Integrated Electromagnetic Brake: Ensures secure holding torque when control power is lost or disabled, preventing axis slippage.
• Robust Environmental Protection: IP65 rated body enclosure suitable for demanding industrial atmospheres.
• Optimized Heat Dissipation: Designed to maintain thermal efficiency during continuous duty cycles.

Applications

• Vertical axis holding and Z-axis control in gantry systems.
• Material handling machinery and heavy-duty transfer cars.
• Packaging machinery and rotary indexing tables.
• Tension control systems and winding operations.

Technical Specifications

Alternative Models & Compatibility

The HF-SP201B features an integrated electromagnetic brake, distinguishing it from the non-braked standard HF-SP201 variant. It is designed for seamless integration with MR-J3-200A and MR-J3-200B servo amplifiers. Ensure that the servo amplifier firmware supports the exact motor parameters to avoid startup initialization errors.

Application Pitfalls & Engineering Notes

The electromagnetic brake installed in this motor is designed strictly for static holding purposes and must not be used for dynamic deceleration or emergency braking. Doing so will cause rapid friction lining degradation and eventual failure of the holding mechanism. Additionally, because of the medium inertia design, ensure your mechanical coupling and gearbox choices are properly sized to handle the peak torque capacity during high-acceleration cycles without mechanical backlash.

Commissioning & Wiring Tips

Proper shielding of the power and brake cables is required to prevent high-frequency electromagnetic interference from corrupting the encoder feedback signal. Connect the shield braid of the encoder cable securely to the amplifier's ground plate. When testing brake operation, verify that 24V DC is applied directly to the brake terminals to release the brake before initiating any rotation commands in the MR Configurator2 environment.
