Product Description:

Bosch Rexroth Indramat manufactures the MDD Synchronous Motors series for integration with its digital drive controllers. The MDD065A-N-040-N2M-095PA0 is a compact rotary actuator that converts drive output into precise mechanical motion for positioning or light-duty process control. With motor size 065 and length code A, the unit occupies little installation space while providing the continuous torque and motion resolution needed in indexing tables, pick-and-place axes, transfer stations, and other repetitive automation tasks where accurate response and repeatable movement are required.

This model is built with standard balancing, so vibration is minimized as the rotor accelerates toward operating speed. A centering diameter of 95 mm seats the flange accurately on a machine frame, while electrical and feedback leads exit on Side A through a single connector interface. At standstill, the motor can deliver 0.8 Nm of continuous torque, and it reaches a nominal speed of 4000 rpm, allowing short cycle times in servo loops without requiring a larger frame. The standard housing protects the stator windings, and the housing geometry together with the keyed shaft helps keep radial load within allowable limits during rapid direction changes.

The unit comes without a blocking brake, so load holding must be handled by external mechanics or drive torque when the axis is stopped. Position data are supplied by an integrated multi-turn absolute encoder, and velocity feedback is transmitted as digital servo feedback (DSF) to the controller for tight loop closure during positioning and speed control. A keyway on the shaft end provides positive torque transmission to couplings, and a shaft seal is present to limit dust or fluid ingress in lightly contaminated machine areas. The shaft end uses the standard format without a side B extension, and all components remain within the normal housing envelope because the motor follows the series' standard dimensions.
