Product Description:

The MDD025B-N-100-N2K-040GD0 is a compact synchronous motor manufactured by Bosch Rexroth Indramat for use with digital drive controllers. It belongs to the MDD Synchronous Motors series and supplies controlled rotary motion to pick-and-place axes, small conveyors, or indexing tables in automated cells. The 025 frame size keeps the footprint minimal while delivering the speed and positioning accuracy needed in tight machine spaces. Its compact format makes it suitable for installations where moving mass and mounting space must both be kept low.

At the mechanical interface, the front flange carries a centering pilot of 40 mm for concentric alignment with gearboxes or mounting surfaces. Power and feedback leads exit on side B of the housing through a connecting cable with coupling unit, which helps keep cable routing orderly in compact machines. The plain shaft is protected by a shaft seal, and no secondary shaft end is provided on the rear. During stall, the motor can generate 0.60 Nm of continuous torque, and its windings support a nominal rotor speed of 10,000 rpm for fast cyclic motion. Length code B and the standard housing keep overall mass low while supporting stable operation in compact axis assemblies.

Position information is supplied by an internal integrated absolute encoder, which allows the drive to track rotor angle immediately after power-up without a reference move. For commutation, the feedback channel also provides resolver feedback, supporting compatibility with legacy digital drives in the MDD platform. The motor is supplied without a blocking brake, so stopping and load holding must be handled by the drive or by external mechanical components. A plain shaft provides a simple torque interface with low runout, and the installed shaft seal helps limit the entry of dust and cutting fluids. These features suit the motor to compact industrial equipment that requires repeatable motion, straightforward integration, and stable feedback performance over frequent operating cycles.
