Product Description:

The MDD065D-N-040-N2M-095PB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current into precise rotary motion for automated positioning and speed control on assembly, packaging, and material-handling axes. It is intended for closed-loop motion tasks where accurate shaft position and stable speed are required during repeated machine cycles.

The centering collar is machined to 95 mm, enabling repeatable concentric mounting in gearboxes and machine frames. During stall, the magnetic circuit delivers 2.7 Nm of continuous torque, so the drive can hold a moderate load without overheating. At rated frequency, the rotor reaches 4000 rpm, providing mid-range speed for pick-and-place axes. The size code 065 with length code D gives the motor the active stack used for its torque capacity and thermal mass. Position data returns through Digital servo feedback (DSF), carried on a single conductor pair. Power and feedback connections exit on Side B, which keeps cable routing on one end of the housing. Standard dynamic balancing minimizes vibration, and the standard housing protects the stator without adding extra weight.

Rotor position is captured by an integrated multi-turn absolute encoder, so the controller knows the shaft angle even after power loss. A keyed shaft in the form of a keyway provides positive torque transmission, and a shaft seal is fitted to limit dust or fluid ingress. The motor is supplied without a blocking brake, so standstill holding must come from servo torque or an external clamp. The shaft on side B is omitted in the standard shaft-end configuration, which reduces overall length and helps simplify guarding around the drive end. Keeping the connections and shaft arrangement separated in this way helps the motor fit compact multi-axis machine layouts.
