Mitsubishi Electric HG-KR43BK Servo Motor

The Mitsubishi Electric HG-KR43BK is a low-inertia AC servo motor from the MELSERVO-J4 series, designed for high-precision motion control in industrial automation and equipped with a 22-bit encoder (absolute/incremental) offering roughly 4,194,304 pulses per revolution for fine positioning. It delivers 400 W (0.4 kW) at 200 VAC, with a rated speed of 3000 RPM and a maximum speed up to 6000 RPM, providing a rated torque of about 1.3 Nm and a maximum torque around 4.5 Nm to support crisp, rapid servo responses. The motor uses a keyed shaft with an electromagnetic brake, is IP65 rated to withstand dust and water exposure, and mounts on a flange designed for a ~60 mm frame; it draws approximately 2.6 A and is specified for operation from about 0 °C to 40 °C. In typical industrial settings, it is used in CNC machining centers, robotic systems, conveyors, packaging machinery, and automated production lines where precise positioning, repeatability, and fast cycle times are essential for consistent performance and product quality. The flange-mount design and compact ~60 mm frame facilitate retrofit into existing installations and tight automation enclosures, supporting compact layouts without sacrificing motion precision.
