Mitsubishi HF354S-A51 AC Brushless Servo Motor for HF Series

The Mitsubishi HF354S-A51 is an AC brushless rotary servo motor designed for high-performance motion control within demanding industrial systems. Belonging to the Mitsubishi HF series, this servo motor provides accurate positioning, rapid acceleration, and dependable continuous operation across a variety of automated equipment and machine tools. It operates on a 200 V AC supply voltage class and delivers a rated output capacity of 3.5 kW (3500 W). Built with a straight shaft configuration, the motor produces a rated rotational speed of 3000 RPM, a rated torque of 11.1 Nm, and a stall torque of 22.5 Nm at a rated current of 12 A. Position monitoring and dynamic closed-loop response are maintained via an integrated 20-bit absolute feedback encoder that provides resolution equivalent to 1,000,000 pulses per revolution. The motor features a 176x176 mm flange mounting footprint and carries an IP67 protection degree to resist dust ingress and fluid splashing in harsh industrial environments. Operating reliably in ambient temperatures from 0 to +40 degrees Celsius, it is engineered for precision packaging, material handling, robotics, and production automation.
