Product Description:

The MDD025C-N-100-N2K-040GC0 is a compact synchronous motor manufactured by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Designed as a motor for digital drive controllers, it supplies precise torque and velocity control for pick-and-place tooling, small conveyors, and auxiliary axes in industrial automation. The unit integrates directly with Rexroth drives, giving machine builders a high-speed rotary actuator that occupies minimal panel and mounting space.

Mechanical coupling and installation features follow the standard layout of the 025 frame. A centering collar of 40 mm aligns the motor to the machine housing while balancing remains standard to limit vibration at elevated speed. Power and feedback conductors exit on Side A, and the factory-fitted connecting cable with coupling unit simplifies plug-in wiring during service. The C length code enlarges the active stack without altering the mounting footprint, and the standard housing supplies normal convection cooling. A plain shaft with a shaft seal is provided, and the shaft end on side B is omitted, so external components are driven only from the front face.

Performance data matches the requirements of rapid-cycle servo loops. The motor can hold 0.90 Nm of continuous torque at standstill and accelerates up to 10000 min⁻¹ under nominal drive voltage. Position feedback is delivered by an integrated absolute encoder, and sinusoidal commutation values can also be derived from the built-in resolver feedback, allowing compatibility with legacy amplifiers. Because the unit ships without a blocking brake, retaining torque during power-off must be supplied by the machine mechanics or the drive’s closed-loop current. Standard housing protection is complemented by the shaft seal to resist lubricant ingress, while the specified motor size 025 keeps rotor inertia low for tight following error. The build follows length code C, housing standard, and a standard balancing class.
