Product Description:
The MKD025B-144-GG0-KN is a servo motor produced by Bosch Rexroth Indramat within the MKD Synchronous Motors series. Designed for closed-loop motion axes in industrial automation, it converts drive current into precise rotary movement. This helps actuators, gear stages, and small conveyor sections follow commanded profiles with minimal position error during indexing, positioning, and steady-speed operation. Its synchronous design also supports repeatable motion when paired with a compatible drive and feedback-processing electronics.
The motor provides a continuous standstill torque of 0.9 Nm, allowing holding or low-speed duties without overheating. A flange with a diameter of 54 mm mates to machine frames, while the 40 mm centering spigot ensures concentric alignment between the motor housing and its driven load. Power and feedback lines exit on side B, and the rigid connection box protects terminals against vibration in panel-mounted installations. A shaft seal is fitted to limit lubricant migration and airborne particles from entering the resolver cavity. It also helps protect internal components when the motor operates near light dust, grease mist, or splashed lubricants.
Feedback accuracy is supplied through Resolver feedback; this analog transducer supports relative position detection, so homing routines establish an electrical zero after power-up. Because the unit is delivered without a holding brake, applications that require static load retention must use external clamping or keep the amplifier energized. The rotor projects a plain shaft with no keyway, simplifying coupling to precision collets or bellows couplings where zero backlash is preferred. Motor length code B balances thermal mass with compact depth, and winding code 144 matches the stator to low-capacity inverters common on multi-axis gantries. After startup, the controller must reference the axis before absolute positions are used.
