Product Description:

The MDD025C-N-100-N2K-040FE1 is manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it turns electrical commands into rotary motion for compact automation axes. Size code 025 and length code C define the active stack geometry, and the standard housing supplies the normal heat path required for continuous operation.

Its dynamic rating is led by a nominal speed of 10000 min⁻¹, letting the drive achieve fast index moves in pick-and-place or spindle duties. When the shaft is locked, the windings can sustain 0.90 Nm of continuous standstill torque without thermal overload. A blocking brake is included, providing a static holding force of 1.0 Nm so the axis remains fixed during power loss. Position data is delivered through an integrated absolute encoder, while an internal resolver channel feeds analog feedback to the controller for smooth commutation and loop closure.

Mechanical interface features complete the package. Rotational accuracy is maintained by standard balancing, and a 40 mm centering diameter ensures coaxial alignment when the flange is mounted. Cables exit on the machine’s left flank, a left-side connection that eases routing inside narrow cabinets. Power and feedback are carried by a connecting cable with coupling unit, minimizing installation time. Motion is transmitted through a plain shaft; the design omits a side-B extension to keep overall length short. The assembly is delivered without a shaft seal, so external protection is required if coolant or oil spray is present.
