Product Description:

The MDD090B-N-020-N2L-110GA2 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded electrical energy into regulated rotary motion that positions tooling, conveyors, and gantry axes in automated equipment. The integrated blocking brake safeguards loads when power is removed, making the unit practical for mid-range positioning tasks in continuous-duty production environments.

The motor produces a continuous standstill torque of 7.2 Nm, which is the maximum torque it can apply indefinitely while the shaft remains stopped without exceeding its thermal limit. During operation, it reaches a nominal speed of 2000 rpm, matching common drive controller output ranges for many axes. When power is removed, the blocking brake supplies 11.0 Nm of holding torque so loads remain stationary. Mechanical centering during mounting is set by a flange diameter of 110 mm, aligning the stator housing with gearboxes or machine frames. Position and velocity signals return to the drive through digital servo feedback, enabling high-resolution closed-loop control. Power and signal cabling exit the housing on side A, which keeps all connectors on one face.

Connection hardware uses a keyed connector, allowing quick attachment without wiring individual terminals. The output element is a plain shaft, which is compatible with clamp couplings or press-fit pulleys, and it is equipped with a shaft seal that helps block lubricant ingress from adjacent machinery. Standard dynamic balancing helps minimize vibration at speed, while the B length code keeps mass low for compact axes. A nominal motor size of 090 and the standard housing profile keep the mechanical envelope consistent with other motors in the same platform.
