Product Description:
Bosch Rexroth Indramat manufactures the MKD025A-144-GG0-KN within the MKD Synchronous Motors series. This servo motor is designed to provide controlled rotary motion for small automated stations. It lets drive controllers deliver exact torque and velocity to tooling, indexing tables, or auxiliary axes on packaging and assembly equipment.
The mechanical interface begins with a centering diameter of 40 mm. This circular reference surface keeps the stator concentric to the driven load and minimizes runout after mounting. A square flange measuring 54 mm provides the bolt pattern that couples the motor to gearheads or machine frames. At standstill, the motor can deliver 0.4 Nm of continuous torque, which indicates the holding or low-speed driving force available during indexing cycles. Rotor position is reported through resolver feedback, giving the controller analog sine-cosine signals for fine interpolation across a full revolution. Power and feedback leads terminate in a sealed connection box, simplifying wiring changes because individual conductors can be landed on screw terminals without disturbing the motor housing.
To integrate the motor physically and electrically, the cabling exits on Side B, keeping connections clear of adjacent equipment and aligning with axis layouts that place the load on the opposite face of the flange. The unit is supplied without a holding brake, so static load retention must be handled by the drive or by external locking mechanisms. Size code 025 and length code A indicate a short stack rotor that lowers inertia for rapid start-stop profiles, while winding code 144 matches the stator resistance and inductance to low-power MKD drives. A plain shaft transmits torque directly, and the shaft seal helps keep lubricant from entering the motor interior. Relative position detection is suitable for applications where the control system references the axis after each power-up.
