Product Description:

The MDD112D-N-020-N2M-130PB0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Built for integration with digital drive controllers, the unit converts commanded current into precise rotation for tooling, conveying, and positioning axes across automated machinery. The frame size 112 offers a larger magnetic volume than smaller variants, supplying higher continuous torque density within the same mechanical footprint while the standard housing and balanced rotor maintain dynamic accuracy.

At standstill, the rotor can deliver a continuous torque of 38.0 Nm, allowing the axis to resist load forces without thermal derating. During normal operation, its nominal speed reaches 2000 rpm; this speed range suits general-purpose feed drives that must balance smooth motion with moderate top speed. A centering pilot of 130 mm positions the motor concentrically to couplings and helps minimize runout. Feedback is provided by the built-in integrated multi-turn absolute encoder, which preserves position counts across power loss and simplifies homing routines. The output end carries a shaft seal, so lubricant stays inside the bearing chamber and contaminants are kept out.

All electrical terminations exit on side B through a sealed connector, shortening cabinet depth and providing service access from a single face. Motion data travels over digital servo feedback (DSF), enabling the controller to adjust current vectors quickly during closed-loop operation. For axes where mechanical holding torque is provided externally, the unit ships without a blocking brake, cutting mass and eliminating brake-release delays. A standard housing, standard balancing class, and the absence of a rear shaft extension help keep vibration levels low while preserving compactness.
