Product Description:

The MDD025A-N-100-N2G-040FD1 is a compact synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for use with digital drive controllers, the unit converts electrical commands into high-speed rotation for light pick-and-place axes and spindle accessories in automated machinery. The motor uses the A length code and size 025 housing, which gives it a small footprint for densely packed multi-axis mounts. Its compact format suits motion points where mounting space is limited and fast response is required.

A centering collar with a diameter of 40 mm simplifies alignment to mechanical frames, and power and feedback conductors exit on side B so cables can be routed away from moving loads. The motor is supplied with a connecting cable with a coupling unit that locks to the connector and helps keep the connection secure during machine movement. At standstill, the rotor delivers 0.33 Nm of continuous torque for fine positioning tasks without excessive thermal rise. Dynamic motion uses a rated speed of 10000 rpm, and position plus velocity are monitored through resolver feedback, which provides analog sinusoidal signals that remain stable in electrically noisy environments.

Mechanical holding duty is managed by an internal brake that supplies 1.0 Nm of torque to secure vertical or indexing axes when power is removed. The detachable motor lead assembly can be removed without disturbing nearby sealing surfaces, which helps preserve the connector area during routine handling. The rotor transmits torque through a plain shaft interface that mates with clamp or collet couplings, and the front bearing region is supplied without a shaft seal, so the motor should be mounted in clean zones where coolant or dust ingress is controlled. Standard rotor balancing minimizes vibration at top speed and helps preserve bearing life during continuous duty.
