Product Description:

The MDD090C-N-020-N2M-130PA0 is an AC synchronous servo motor manufactured by Bosch Rexroth Indramat in the MDD Synchronous Motors series. It couples to digital drive controllers and converts commanded current into regulated rotary motion for positioning, feed, and auxiliary axes on machine tools, printing presses, and material-handling cells. Electronic commutation and a permanent-magnet rotor give the motor the fast response needed for repeatable automation cycles.

At standstill, the stator can deliver a continuous torque of 10.4 Nm, so an axis can support static loads without additional mechanical locks. During operation, it reaches a nominal speed of 2000 rpm, which is the rated mechanical output point used for drive sizing and thermal calculations. Position data are generated by an integrated multi-turn absolute encoder; this device tracks shaft angle across multiple revolutions and eliminates homing moves after power-up. That encoder feeds the drive through digital servo feedback, allowing the controller to close high-bandwidth position and velocity loops. A shaft seal is fitted at the output end to limit the ingress of coolant or dust into the bearing cavity and help maintain service life when the motor is mounted inside splash zones.

A centering diameter of 130 mm aligns the flange precisely to adjacent housings and keeps radial runout low. Power and feedback connectors are oriented on Side A, simplifying cabling when the motor is installed against a fixed machine wall. For applications that rely on dynamic torque from the drive rather than mechanical restraint, the unit is supplied without a blocking brake. Output torque is transmitted through a shaft machined with a keyway, providing positive engagement with pulleys or couplings. The motor also uses standard balancing, a C length code, and a molded connector housing.
