Mitsubishi HG-KN23K 200W 200V AC Low-Inertia Servo Motor with Keyway Shaft

The Mitsubishi HG-KN23K is a compact, low-inertia servo motor designed for the MELSERVO-JE motion-control system. With a rated capacity of 200 W, the motor delivers 0.64 N·m rated torque and 1.9 N·m maximum torque. Its rated speed is 3,000 r/min and maximum speed is 5,000 r/min, providing the controlled and responsive rotary motion required by many small-capacity automation systems.

For position and speed feedback, the HG-KN23K uses a 17-bit encoder with 131,072 pulses per revolution. Its low-inertia design, combined with a keyway shaft, allows the motor to respond efficiently to changes in commanded motion. The motor has an IP65 protection class and compact dimensions of approximately 60 mm × 60 mm × 106.6 mm, with a listed weight of about 0.91 kg.

The HG-KN23K is suitable for applications where compact size, responsive motion and precise feedback are important. It can be incorporated into compatible Mitsubishi servo systems used for industrial machinery, positioning equipment, assembly equipment, material-handling mechanisms and other automated machines. When replacing an existing servo motor, the motor model, shaft configuration, encoder specifications and compatible servo amplifier should be checked carefully to ensure proper system matching.
