Mitsubishi HG-KN23JK 200W 200V AC Servo Motor with Keyed Shaft and Oil Seal

The Mitsubishi HG-KN23JK is a compact AC servo motor in the HG-KN series, developed for applications requiring controlled speed, positioning accuracy and responsive rotary motion. With a 200 W rated output, 3,000 r/min rated speed and 5,000 r/min maximum speed, the motor is suited to small-capacity motion-control systems where compact dimensions and low inertia are important. Its rated torque is 0.64 N·m, with a maximum torque of 1.9 N·m.

The motor incorporates a 17-bit encoder providing 131,072 pulses per revolution, supporting high-resolution feedback for closed-loop servo control. It uses a keyway shaft and includes an oil seal, while the totally enclosed, natural cooling structure provides an IP65 protection rating. Its 60 × 60 mm flange and approximately 77.1 × 60 × 118 mm dimensions make the HG-KN23JK suitable for machinery where installation space is limited.

The HG-KN23JK is part of Mitsubishi's MELSERVO-JE servo system and is matched with compatible MR-JE servo amplifiers, with the 200 W motor commonly paired with the MR-JE-20A/B family. Its low-inertia characteristics make it suitable for compact automation equipment, positioning mechanisms, machine tools, assembly machinery, material-handling equipment and other applications requiring reliable servo-based motion control.
