Mitsubishi HF154BS-A48 AC Brushless Servo Motor with Brake

The Mitsubishi HF154BS-A48 (HF154BS-A48) is a rotary AC brushless servo motor engineered for precise motion control in Mitsubishi HF Series drive systems. Operating on a 200 VAC supply voltage class, this compact servomotor delivers a rated output of 1.5 kW (1,500 W) with a rated rotational speed of 3,000 RPM. It provides a rated torque of 4.8 Nm, a stall torque of 9 Nm, and draws a rated current of 5.6 A. Designed for demanding industrial environments, the motor features an IP67-rated enclosure and operates effectively in ambient temperatures ranging from 0 to +40 degrees Celsius. Mechanical and electrical integration is facilitated by a 130x130 mm mounting flange and a straight shaft configuration. The unit features an integrated electromagnetic holding brake for holding position during power loss or emergency stops. For accurate position and velocity feedback, the motor incorporates a built-in 18-bit absolute encoder providing resolution equivalent to 260,000 pulses per revolution. This servo motor is typically used in automated production machinery, CNC equipment, robotics, packaging lines, and high-precision positioning axes.
