Mitsubishi HG-KR23K Rotary AC Servo Motor for MELSERVO-J4

The Mitsubishi HG-KR23K (HG-KR23K) is a rotary brushless AC servo motor engineered for high-precision industrial motion control within the MELSERVO-J4 series drive ecosystem. Designed with a straight shaft and an integrated oil seal, this industrial servo motor delivers reliable dynamic response for automated machinery, robotics, and positioning systems. It incorporates a built-in 22-bit absolute feedback encoder providing high-resolution position detection equivalent to 4,194,304 pulses per revolution. Operating on a 400 V AC supply class, the unit delivers a rated output of 1,500 W (1.5 kW) with a nominal rated current of 5.4 A. The motor delivers a continuous rated torque of 4.8 Nm at a rated rotational speed of 3,000 rpm. The mechanical assembly features a 90x90 mm flange mounting configuration and dual MS-type connectors for secure electrical and feedback connections. Engineered for demanding industrial environments, the motor offers an IP67 degree of protection against dust and liquid ingress and operates reliably across an ambient temperature range of 0 to +40 degrees Celsius. It serves as an equivalent replacement for HGJR1534 units in compatible automation setups.
