Mitsubishi Electric HG-MR43 AC Servo Motor

The Mitsubishi Electric HG-MR43 AC Servo Motor is a 400W, 200 VAC-class servo motor in the Mitsubishi MELSERVO-J4 (HG Series) family that delivers high-precision positioning, rapid speed control, and reliable torque for industrial machinery. It features a high-resolution absolute encoder, a straight keyed shaft, and self-cooled cooling with IP65 protection (excluding the shaft area) and flange mounting for easy integration. Rated up to about 3000 RPM, this motor is well suited for compact, high-performance drives in CNC machines, packaging equipment, robotics, and assembly lines. Common applications include pick-and-place systems, conveyor automation, labeling machines, semiconductor equipment, and other precision manufacturing processes requiring smooth, repeatable motion. The HG-MR43 is commonly used for replacement, retrofit, or upgrade of servo-driven systems, with cross-refs such as Mitsubishi HG-KR43, HF-KP43, and HC-KFS43.
