Product Description:
Bosch Rexroth Indramat manufactures the MKD025A-144-GP0-KN, a compact servo motor in the MKD Synchronous Motors series. The unit converts drive output from a compatible inverter into controlled rotary motion for pick-and-place heads, small conveyors, and other precise axes in industrial automation. Its design balances low inertia with adequate holding torque so closed-loop velocity and position corrections can be executed quickly while maintaining the repeatability demanded by packaging machines, semiconductor tooling, and light assembly stations. Because the motor is intended for continuous duty inside electrical cabinets, it uses onboard terminals to simplify wiring in multi-axis assemblies.
The mechanical interface starts with a centering shoulder of 40 mm, allowing the stator housing to seat accurately against matching machine frames and minimize axial runout. Power and feedback leads exit on Side B, a layout that helps prevent cable loops from interfering with driven components when the motor is mounted flush to a panel. All terminations are contained in a connection box, which provides strain relief and helps maintain EMC shielding continuity. At standstill, the motor can deliver 0.4 Nm of continuous torque, a level suitable for fine-indexing tables. Rotor position is monitored through resolver feedback (RSF), which provides analog sine-cosine signals that high-resolution servo drives can interpret without additional electronics.
The mounting flange measures 54 mm square, so the motor fits compact linear stages and small gearheads without adapter plates. A keyed output shaft, specified as a shaft with keyway, permits direct coupling, while the integral shaft seal helps keep lubricants and contaminants out of the bearing cavity. Coil set designation 144 identifies the winding data required by the drive, and series size 025 marks the overall magnetic frame class used across the MKD family. Motor length code A shortens the rotor stack to reduce mass, and relative position detection simplifies homing routines during startup.
