Product Description:

The MDD090C-N-040-N2M-130PL2 is a synchronous AC motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Built for integration with digital drive controllers, the unit converts commanded current into precise mechanical rotation for indexing tables, pick-and-place heads, and similar positioning axes. Its standard housing allows installation in machine frames without additional protective shrouds. The motor supports automated duty cycles that demand high acceleration and repeatable velocity regulation.

At its rated operating point, the rotor can turn at 4000 rpm while producing a continuous standstill torque of 10.4 Nm. A blocking brake delivers 11.0 Nm of holding torque to secure the load when the drive is de-energized. The centering diameter of 130 mm matches Rexroth flanges and helps maintain concentric alignment with driven equipment, while standard balancing keeps residual vibration within ISO limits. Power and feedback conductors exit on the left side through a molded connector, which can simplify wiring where right-hand access is limited. The housing uses a standard closed design that resists airborne oil and dust.

In position-servo applications, the integrated measurement system combines an integrated multi-turn absolute encoder with Digital servo feedback (DSF), allowing the controller to read absolute rotor angle after power-up with two-way data integrity. The motor length code C indicates the active stack height within the 090 frame. A machined shaft with a keyway provides positive coupling to pulleys or couplings, and a factory-installed shaft seal helps keep grease and coolant out of the bearing cavity. The standard shaft end is on side A, with no extension on side B, which reduces overhung mass. Connection hardware uses a locking circular connector.
