Product Description:
The MKD025B-058-KG1-KN is a servo motor produced by Bosch Rexroth Indramat within the MKD Synchronous Motors series. It is intended for industrial automation tasks that require precise electromechanical conversion on feeders, small gantries, and indexing tables. By supplying commanded torque and speed to the drivetrain, the motor helps the controller position loads quickly and repeatably in a closed-loop motion system. That makes it suitable for compact machine modules where accurate starts, stops, and short motion cycles are important. Its compact frame supports installation in tight machine spaces where larger servo motors would be harder to place.
A flange diameter of 54 mm suits compact mounting faces and miniature gearboxes. At standstill, the motor can deliver a continuous torque of 0.9 Nm, and the integral brake provides 1 Nm to hold the axis when power is removed. This combination supports use on small axes that need stable holding without a large mechanical envelope. Housing seals and molded connectors support an IP65 rating, which helps keep out dust and low-pressure water jets. Motion accuracy is supported by a closed-loop error band of ±8 angular minutes. Cabling enters on side B through a connection box, and class F insulation allows winding temperatures up to 155 °C. The motor also has length code B, size 025, and a plain shaft for torque transmission.
A centering pilot of 40 mm keeps the flange aligned to the machine face during mounting. The permissible ambient range is 0–40 °C, which supports normal operation without excessive thermal rise. Integrated feedback supports position tracking beyond 4096 revolutions, reducing the need for repeated homing after power cycles. The winding code 058 matches the motor's electrical characteristics to the connected drive and helps maintain smooth low-speed operation. A factory-installed shaft seal is also present to help protect internal components during extended duty.
