MDD041C-N-100-N2G-050MB0
The MDD041C-N-100-N2G-050MB0 is a synchronous motor manufactured by Bosch Rexroth Indramat and supplied as part of the MDD Synchronous Motors series. Designed for digital drive controllers, it converts electrical power from the drive into controllable mechanical rotation for positioning, velocity, or continuous-duty tasks in automated machinery. The unit fits compact axes where high speed and low inertia are required. Its standard housing permits direct mounting, and the rotor is balanced to a standard grade so couplings can operate without undue vibration.
This model reaches a nominal speed of 10000 rpm, enabling fast indexing or spindle duties without mechanical gear reduction. At standstill, it sustains 2.05 Nm of continuous torque, so holding force is available during dwell periods while thermal limits remain respected. A centering diameter of 50 mm aligns the stator face accurately against machine frames and helps limit radial runout. The motor belongs to size 041, which is the frame designation used for the flange outline and winding envelope across the series. All power and feedback conductors exit on side B, and the electrical interfaces use a sealed connector that simplifies cable routing and protects the connection point.
Position and velocity loops reference the built-in resolver feedback, which delivers rotor angle information with strong noise immunity for drives that sample at very short intervals. Length code C identifies the active stack depth and matches the motor's thermal mass to its continuous output without increasing the flange footprint. Torque is delivered through a shaft machined with a keyway, giving a positive mechanical lock to pulleys or couplings. Because the motor is supplied without a shaft seal, the front bearing should be protected from fluid exposure. The design also comes without a blocking brake, and the shaft is present only on the drive side in the standard format.
