Mitsubishi HF-H204BS-A51 HF Series 2.0 kW AC Servo Motor with Brake

The Mitsubishi HF-H204BS-A51 (HF-H204BS-A51) is an industrial AC brushless rotary servo motor engineered for high-precision positioning and dynamic motion control in Mitsubishi HF Series drive systems. Operating on a 400 VAC class power supply, this servo motor delivers a rated output capacity of 2.0 kW (2000 W) with a rated current of 3.4 A. It features a rated rotational speed of 3,000 rpm, generating a rated torque of 6.4 Nm and a peak stall torque of 13.7 Nm, ensuring responsive performance during demanding acceleration and deceleration cycles. Designed for robust operation, the unit includes a straight shaft, a built-in electromagnetic brake for secure holding during power loss, and an integrated 20-bit absolute feedback encoder providing 1,000,000 pulses per revolution (1 mega-pulse per revolution) for precise position tracking without homing routines. The motor is housed in a compact frame with a 114.3 x 114.3 mm flange mounting footprint and carries an IP67 protection rating, shielding internal components from dust ingress and water exposure. It operates reliably within an ambient temperature range of 0 to +40 degrees Celsius, making it ideal for CNC machinery, robotic handling, and automated manufacturing systems.
