Product Description:

The MDD090B-N-030-N2L-110GA1 synchronous motor belongs to the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. Built for digital drive controllers, it converts controlled current into torque and speed so automated lines can position loads, follow velocity profiles, or maintain tension. The unit fits into modular machine frames through its standard housing and keyed connector system, giving machine builders a compact rotary actuator for mid-frame axes. Its synchronous design supports stable motion behavior during positioning, speed regulation, and other closed-loop tasks.

At zero speed, the motor delivers a continuous standstill torque of 7.2 Nm, meaning the rotor can hold or slowly move loads without overheating. Under rated excitation, the motor reaches a nominal speed of 3000 rpm, which suits many servo applications that use direct coupling or gear reduction. Accurate mechanical centering is supported by a 110 mm centering diameter, which helps align the flange to servo gearboxes while minimizing radial runout. Power and feedback cables exit on Side A, which can simplify routing when the motor is installed near fixed machine panels or guarding. Position and velocity information returns to the controller through digital servo feedback, allowing precise closed-loop response during changing load conditions.

For holding requirements during idle periods or emergency stops, an integrated brake supplies 6.5 Nm of static torque. The brake is a blocking brake, so the shaft locks when power is removed. The frame is size 090 with length code B, giving the motor proportions suited to medium-duty axis layouts. A sealed output section uses a plain shaft with a shaft seal to help prevent lubricant loss and particle ingress. Standard balancing helps reduce vibration during operation, and the single-ended shaft arrangement leaves the opposite side available for internal functional components.
