Product Description:
The MDD090B-N-040-N2M-130GB1 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 supplies tightly regulated rotary motion to indexing tables, packaging axes, and other automated equipment. The motor is built in a standard housing and uses standard dynamic balancing, so vibration remains controlled as the rotor accelerates to operating speed. Because it works with digital drive controllers, commanded changes in speed and direction can be corrected through feedback during repeated motion cycles.
The centering diameter measures 130 mm, enabling precise seating against mounting flanges or gearheads. This fit also helps align the shaft with the driven load to reduce coupling stress during operation. Power and feedback conductors exit on Side B through an industrial connector, which helps keep cable routing orderly inside a control cabinet. Under continuous excitation, the stator produces 7.2 Nm of torque at standstill, while an integrated blocking brake secures the load with up to 6.5 Nm after power removal. During operation, the rotor follows drive frequency linearly up to a nominal speed of 4000 rpm, allowing fast positioning cycles without exceeding the thermal limits of the B-length stator stack.
The feedback loop uses digital servo feedback (DSF) from an integrated multi-turn absolute encoder, so the controller retains position data even after a complete shutdown. This arrangement is useful on axes that rotate through more than one revolution and still need accurate position tracking when power returns. Output power is transferred through a plain shaft, and the end is supplied without a secondary extension on side B; a shaft seal helps block coolant spray and dust ingress. With its frame size of 090 and length code B, the motor balances inertia and peak torque for mid-range automation tasks. A plain shaft also allows use with common clamping hubs and couplings found on servo-driven machinery.
