Product Description:

The MDD025B-N-100-N2K-040GC0 is a brushless servo motor produced by Bosch Rexroth Indramat for use with digital drive controllers and belongs to the MDD Synchronous Motors series. Designed as a compact motor type for rapid positioning tasks, it converts electrical commands from the drive into precise torque and speed for machine axes in industrial automation. A plain shaft, standard housing, and standard dynamic balancing allow mounting in light-duty motion modules where minimal vibration and compact space usage are required.

The motor reaches a nominal speed of 10000 rpm, allowing high axis velocities when the drive applies rated frequency. Continuous torque at standstill is 0.60 Nm, so closed-loop regulation can hold small loads without overheating at zero speed. A centering diameter of 40 mm aligns the stator accurately in the machine frame and helps maintain concentric operation. Power and feedback conductors exit on side A, simplifying routing when the unit is coupled directly to gearheads or belt pulleys on the opposite side. Position data is generated by an integrated absolute encoder, giving the drive a unique multi-turn angle value after every power-up and removing the need for homing cycles.

In applications where sealing is required, the motor is supplied with a shaft seal, which helps prevent lubricant migration into the stator air gap and supports IP65 protection when combined with the standard housing. For holding duties, the design is without a blocking brake, so any stationary torque must come from the drive or from external clamping devices. Electrical power reaches the stator windings through a connecting cable with coupling unit, which provides a plug-in connection for installation while matching the plain shaft and standard motor format used on size 025 with length code B.
