Product Description:

The MDD025A-N-100-N2K-040FA0 is a small-frame synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is supplied for use with digital drive controllers and is intended to deliver high rotational speed on compact axes in assembly systems and electronics handling equipment. The short frame helps the motor fit into confined machine spaces where a larger housing would limit motion hardware. As part of an automation system, the unit converts electrical drive commands into mechanical rotation with precise response for small moving loads.

The motor can sustain 0.33 Nm of continuous torque at standstill, which is enough to hold lightweight fixtures while the drive remains energized. A rated speed of 10000 rpm supports rapid indexing when it is paired with a matching inverter. The flange centering recess has a diameter of 40 mm, which helps align the stator to the machine plate and maintain accurate shaft positioning. Power and feedback conductors exit on side A, which can simplify cable routing when the shaft faces the operator. The motor uses a connector termination, and the output interface is a plain shaft, so couplings clamp directly to the hardened steel journal.

Dynamic operation is supported by standard balancing, which helps the motor run smoothly at high speed. Position data come from an integrated absolute encoder, allowing the drive to track rotor position for closed-loop motion control. The unit is supplied without a blocking brake, so any holding function must come from the controller or an external mechanical device when power is removed. There is no shaft seal, and the shaft end is provided only on the drive side rather than in a through-shaft arrangement. The standard housing and keyed connector layout support straightforward installation in compact servo assemblies.
