MKD025A-144-GG0-KN

The MKD025A-144-GG0-KN is a compact servo motor manufactured by Bosch Rexroth Indramat and belongs to the MKD Synchronous Motors series. Intended for use with the company’s digital drive controllers, the unit converts controlled current into rotary motion so that automated axes can achieve repeatable speed and position targets in assembly cells, small material-handling systems, or light-duty packaging stations.

The motor registers to the machine frame through a centering diameter of 40 mm, while a flange that measures 54 mm determines the bolt pattern for mounting. At standstill it can deliver a continuous torque of 0.4 Nm, allowing low-inertia loads to hold position without overheating. Power and feedback conductors exit on Side B; this fixed orientation simplifies cabinet layout in multi-axis installations. Wiring is completed inside a sealed Connection box, which protects terminals from dust and coolant splash on the production floor.

Rotor position is measured by an integrated Resolver feedback (RSF) device that provides relative angle data for closed-loop control. The motor is supplied without a holding brake, so external mechanical measures are required if static load retention under power-off conditions is necessary. A Plain shaft transmits torque directly to couplings or pulleys, and a shaft seal is present to limit ingress along the shaft bore. Winding code 144 defines the copper fill and insulation scheme used for this design, while length code A and size code 025 keep the overall envelope small for tight mounting zones.
