Product Description:
The MKD025B-144-KP0-UN is a servo motor produced by Bosch Rexroth Indramat and belongs to the MKD Synchronous Motors series. As a compact rotary actuator, it supplies continuous rotational power to automated axes, transfer units, and light pick-and-place modules that require accurate speed and torque control. The motor works with controlled AC drive systems and sends position and velocity feedback directly to the drive controller through its integrated sensors. Because the feedback system is built into the motor, the connected drive can monitor rotor movement continuously during acceleration, steady-state running, and deceleration.
Mechanically, the unit mounts to machinery with a flange measuring 54 mm, and a centering recess of 40 mm keeps the housing aligned with the driven assembly. The rotor provides a continuous standstill torque of 0.9 Nm, which allows steady holding or slow indexing duty without overheating when the application is properly matched. Torque is transmitted through a keyway shaft, and the power and encoder connectors sit on a plate that can be positioned within a 270° rotation range. The adjustable connector orientation helps route cables in confined machine spaces and reduces bending stress at the cable exit. The compact mounting dimensions also help the motor fit small axis layouts where surrounding guards, slides, or tooling leave little installation space.
The rear housing contains resolver feedback, and multi-turn position tracking is supported by absolute feedback for more than 4096 revolutions, allowing the controller to recover position after a power cycle. Resolver signals are well suited to industrial environments because they tolerate vibration and electrical noise during operation. A dedicated shaft seal helps protect the bearing area from splash and fine dust. The motor is supplied without a holding brake, so static holding must be provided by external means when the axis is at rest. The motor uses winding code 144, which identifies the electrical winding used with the matching drive.
