MDD025B-N-100-N2K-040MF1
The MDD025B-N-100-N2K-040MF1 is a servo motor produced by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Intended for digital drive controllers, it delivers rapid rotational positioning in compact automation axes. Size code 025 and length code B place the unit in the small-frame class favored for pick-and-place heads, labeling stations, or light spindle tasks where limited inertia and high speed are required. Its compact format helps it fit densely packed machine layouts where moving mass must stay low for responsive indexing. An integrated feedback device supplies position data directly to the controller, eliminating external feedback hardware.
At standstill, the motor can supply a continuous torque of 0.60 Nm, which is suitable for holding light loads without overheating. During motion, it reaches a nominal speed of 10,000 rpm, enabling short cycle times. A blocking brake is installed, and its static holding capacity is 1.0 Nm, which helps prevent axis drift when power is removed. Mechanical alignment relies on a centering pilot of 40 mm, so the mounting flange must match that register. The power and feedback plugs exit on the right side, which can simplify cable routing where the motor is mounted close to guards or linear slides. Rotor balancing is standard, and the housing follows the series standard pattern.
Power is transmitted through a shaft machined with a keyway, giving a positive drive interface for pulleys or couplings. The unit is supplied without a side-B shaft, so all torque is available at the primary end. Feedback accuracy is maintained by the built-in resolver feedback, which resists electrical noise and suits the motor’s high-speed range. The housing is shipped without a shaft seal, so an external seal may be needed when contamination is a concern. Electrical connection is handled by a factory-fitted connecting cable with coupling unit, which reduces assembly effort and keeps the leads bundled in a compact arrangement. This setup also reduces the number of separate connection parts around the motor.
