Mitsubishi FK4-075-100-LP4 AC Servo Motor for MELSERVO J2S Series

The Mitsubishi FK4-075-100-LP4 (FK4-075-100-LP4) is a high-power brushless rotary AC servo motor engineered for use with Mitsubishi Electric MELSERVO J2S series automation systems. Delivering a rated power output of 22 kW and a rated torque of 105 Nm at a nominal operating speed of 2,000 rpm, this motor provides robust dynamic response and precise motion control in heavy-duty industrial machinery. It operates on a 200 VAC class supply voltage with a rated current draw of 112 A. Equipped with an integrated 17-bit absolute encoder offering 131,072 pulses per revolution, the motor ensures accurate position and velocity feedback for demanding automation processes. The physical construction features a keyed shaft for secure mechanical torque transfer, an integrated oil seal to protect against oil ingress, and a 250 x 250 mm mounting flange. Built to an IP44 degree of protection, the FK4-075-100-LP4 provides reliable performance in harsh manufacturing environments, serving as a critical replacement motor for legacy MELSERVO J2S installations.
