Product Description:

The MDD071A-N-040-N2T-095PB2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into precise rotary motion for positioning or velocity loops in industrial automation. The unit uses a standard housing and standard dynamic balancing, so it can be mounted without special vibration countermeasures. A keyway shaft, delivered without a second shaft end on side B, allows direct coupling to pulleys or gearboxes, while the integrated blocking brake secures the load during power-off states.

The motor’s nominal mechanical limit is 4000 rpm. At standstill, it can deliver 2.2 Nm of continuous torque for low-speed indexing or controlled holding. For short stops, the blocking brake supplies an additional holding capacity of 6.5 Nm, which helps prevent axis drift when the drive is disabled. Accurate centering is assisted by a flange recess of 95 mm, which matches standard machine frames and helps reduce radial runout. Protection against lubricant ingress is provided by a shaft seal, allowing installation in light oil-spray environments without external covers. Standard balancing keeps residual vibration low, and the A-length stator package limits the axial envelope while supporting heat dissipation.

Power and feedback connectors are oriented on Side B, which can simplify cable routing in gantry or linear modules. A keyed round connector carries phase power, and an integrated multi-turn absolute encoder transmits position data with single-turn and revolution counts. Feedback signals follow Digital servo feedback (DSF), allowing real-time velocity loops inside Rexroth drive controllers. The motor length code A and frame size 071 keep the package compact while leaving room for the required windings. A standard housing finish eases cleaning, and the keyway shaft profile supports straightforward mechanical alignment without additional bushings.
