Product Description:

The MDD025C-N-100-N2K-040GD1 is a compact servo unit manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts electrical commands from a matching Rexroth drive into precise shaft rotation for indexing tables, miniature actuators, and pick-and-place modules used in automated lines. Its integrated feedback system and compact mechanical layout support continuous-duty operation in applications that need repeatable positioning, quick response, and stable motion over frequent start-stop cycles.

The mechanical interface follows the standard balancing grade, and the flange provides a centering diameter of 40 mm to align the motor precisely on gearboxes or machine frames. Power and feedback conductors exit on side B through a connecting cable with a coupling unit, which helps reduce installation depth. When the rotor is stationary, the motor can sustain a continuous torque of 0.90 Nm, and the integrated blocking brake adds holding capability up to 1.0 Nm during power-off conditions. Position data is supplied by an integrated absolute encoder, while a resolver is used for commutation and velocity control. Rated operation reaches a nominal speed of 10000 rpm, which supports fast cycle times in compact mechanisms. The plain shaft is delivered without a secondary shaft end.

The housing has a compact enclosure that simplifies mounting inside tight cabinets or densely packed machine spaces. Within the MDD product line, the motor is identified by size code 025, which helps keep mass and inertia low for lightweight axes. Length designation C indicates a deeper stator stack than the shorter A or B versions. Protection against lubricant ingress is enhanced by a shaft seal, which supports installation on gear reducers or linear modules where splashed coolant is present.
