Product Description:

The MDD025C-N-100-N2K-040MC0 is produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it provides compact rotary actuation for small automation stages and tooling heads. The design follows the series conventions with motor size 025 and length code C, giving a narrow stator package that fits into restricted mounting spaces. Standard dynamic balancing minimizes residual vibration, and the standard cast housing supports natural convection cooling. A single shaft end on the drive side simplifies integration when no auxiliary load connection on side B is required.

Mechanical interface and continuous output limits define how the unit fits into a motion axis. The centering pilot is 40 mm, so the flange locates accurately on precision machine plates. Power and feedback conductors exit on Side A, and a connecting cable with coupling unit provides a sealed electrical hand-off without hard-wiring inside the cabinet. At standstill the motor can deliver 0.90 Nm of continuous torque, enabling stable holding or slow positioning under load. During operation it can reach a nominal speed of 10000 min⁻¹, giving high surface velocities for small spindles and rapid indexing tables while keeping iron losses within the thermal envelope defined for this frame.

Position quality and safety functions are handled by an integrated absolute encoder, which reports multi-turn shaft position directly to the drive. For servo loop closure the drive reads resolver feedback signals originating from the motor windings, allowing robust angle detection even at top speed. Because the unit is supplied without a blocking brake, any static holding torque must be generated electrically or by external mechanics. The keyed shaft follows a keyway profile for positive torque transfer, and the design omits a shaft seal to reduce friction in dry cabinet environments. These features complete the standard configuration for precision, lightweight servo axes.
