Product Description:

The MDD025B-N-100-N2K-040MA0 is a compact synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed as a motor for digital drive controllers, it supplies precise torque and speed in small-frame automation axes such as pick-and-place heads or miniature spindles. A standard housing and balancing class keep vibration low, while the model is delivered without a blocking brake and without a shaft seal, so any static holding or liquid ingress protection must be handled by the host machine.

This motor can maintain a continuous standstill torque of 0.60 Nm, enabling steady force output for positioning tasks under thermal equilibrium. Its rated operating velocity reaches 10000 min⁻¹, a speed that supports high cycle rates when paired with a suitable inverter. The centering diameter of 40 mm aligns the stator precisely on mounting flanges, minimizing radial runout. Power and feedback conductors exit on Side A, allowing cables to be routed in a single direction and reducing bundle clutter. Because the shaft end is supplied only on the drive side, inertial load is confined to one overhung mass, which helps the resolver feedback system track rotor position accurately during rapid reversals.

Cabling is completed through a single Connector that carries phase power, resolver lines, and thermal conductors in a keyed shell for secure connection. Inside the housing, an integrated absolute encoder provides multiturn position data, while the resolver circuit supplies additional angle feedback to the drive. A keyed output shaft with a keyway simplifies torque transmission to pulleys or miniature couplings, and the motor size code 025 together with length code B identifies the 25-series frame and intermediate body depth used to standardize mount patterns across the range.
