Product Description:
The MKD025B-144-KP1-KN is a compact servo motor produced by Bosch Rexroth Indramat within the MKD Synchronous Motors series. It is intended for closed-loop motion axes in which a small frame must deliver repeatable torque and precise feedback to the drive controller. Used in packaging heads, pick-and-place arms, or miniature positioning tables, the motor converts electrical power from the associated inverter into mechanical rotation for industrial automation tasks.
A centering pilot of 40 mm positions the housing concentrically on the machine flange and helps keep radial runout low. Continuous stall capability is rated at 0.9 Nm, allowing the motor to hold load torque when cooling conditions remain within the specified range. Rotor angle is reported through resolver feedback, giving analog sine-cosine signals directly to the drive for commutation and velocity control. Power and feedback conductors exit on side B, so cabinet wiring approaches the rear of the motor. Winding designation 144 identifies the coil impedance and thermal characteristics used with compatible Indramat drive amplifiers.
The permanent-magnet brake supplies 1 Nm of static torque to secure vertical or overhung loads when power is removed. A square mounting interface of 54 mm matches ISO flange patterns common on small gearheads and slides. Multi-turn position tracking remains available because the resolver is combined with an internal counter that provides absolute resolution of more than 4096 revolutions, eliminating homing cycles after shutdowns. Rotational energy is transmitted through a shaft with a keyway, and a shaft seal is fitted to limit the ingress of dust or coolant. The motor has length code B and a size 025 frame. A molded connection box terminates the power, brake, and feedback conductors in a single enclosure.
