Mitsubishi HC-UFS43B 400W AC Servo Motor with Brake for MELSERVO-J2S

The Mitsubishi HC-UFS43B (HC-UFS43B) is an industrial AC brushless rotary servo motor engineered for precise motion control applications within the MELSERVO-J2S series. This compact drive unit delivers a rated output of 400 W (0.4 kW) with a rated speed of 3,000 RPM and a rated torque of 1.3 Nm. It operates on a 200 VAC power supply class with a rated current draw of 2.8 A. Built for demanding industrial machinery, the motor includes a straight shaft, an integrated electromagnetic holding brake, and an oil seal to prevent fluid ingress. Position feedback is provided by a high-resolution 17-bit absolute encoder, delivering 131,072 pulses per revolution for accurate positioning and smooth velocity control. The motor features an 80 mm by 80 mm flange mounting configuration and an IP65 ingress protection rating, safeguarding internal components from dust and water spray. Designed to operate reliably in ambient temperatures ranging from 0 to +40 degrees Celsius, this servo motor is commonly utilized in automated packaging machines, material handling systems, textile equipment, and CNC positioning axes.
