Product Description:

Bosch Rexroth Indramat manufactures the MDD090B-N-030-N2M-130PL0 in the MDD Synchronous Motors series. The unit is a permanent-magnet servo motor intended for digital drive controllers where fast position loops and repeatable motion profiles are required in automated machinery. It converts commanded current into regulated torque and speed for axes such as pick-and-place arms, gantry slides, or indexing tables in packaging, printing, and material-handling lines. Its servo design supports accurate response during acceleration, steady running, and repeated stopping cycles. In closed-loop service, the motor is used where commanded motion must be tracked consistently from cycle to cycle under varying loads.

The motor can deliver a continuous standstill torque of 7.2 Nm, giving the drive a reference for holding force when the shaft is energized but not rotating. Its nominal speed is 3000 rpm, which is the rated synchronous operating speed under matching electrical conditions. Mechanical alignment during mounting is aided by a centering diameter of 130 mm, which helps seat the motor concentrically in the machine interface. Power and feedback leads exit on the left side, which affects cable routing around nearby structures. The motor is supplied without a blocking brake, so any holding function during power loss must be provided externally.

High-resolution feedback is provided by an integrated multi-turn absolute encoder working together with digital servo feedback (DSF). This arrangement gives the drive absolute position data across multiple revolutions, which supports restart behavior without a new homing cycle and helps maintain axis synchronization. This feedback method also allows the controller to monitor rotor position continuously while coordinating motion with other servo axes. Torque is transmitted through a keyway shaft that fits common hub connections, and the output end is built with a shaft seal to limit contamination at the bearing area. The motor also uses a standard housing, normal balancing grade, motor size 090, motor length code B, and a rear connector interface for typical installation layouts.
