Product Description:
The MDD090B-N-030-N2M-110GA1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts electrical commands into mechanical rotation for axis control in automated machinery. In industrial automation, it supports closed-loop positioning, velocity, and torque regulation in packaging lines, machine tools, and handling systems. Its synchronous design allows the drive to maintain accurate motion response during changing loads and repeated duty cycles, which is useful in indexing tables and feed axes.
The unit delivers a continuous standstill torque of 7.2 Nm, allowing static load support without overheating when motion is paused. Under rated excitation, it reaches a nominal speed of 3000 rpm during steady operation. The integrated blocking brake applies 6.5 Nm of holding torque to secure vertical or suspended axes when power is removed. Frame designation 090 identifies the motor size and pairs with length code B for this housing format. Position and velocity are reported through digital servo feedback (DSF), allowing the controller to monitor rotor movement with high resolution. The motor can support applications that alternate between steady running, precise stopping, and short holding periods at standstill.
The flange has a centering diameter of 110 mm, which helps align the motor accurately on gearboxes or mounting plates. Cables exit on Side A, and a keyed connector carries both power and signal lines to keep routing compact around the machine. A standard balancing grade reduces residual vibration while the plain shaft turns at operating speed. Protection against lubricant migration is provided by a shaft seal, which helps protect the bearing area and encoder cavity. The housing remains in the standard form without optional cooling fins, and there is no shaft end on side B. With the connector and cable exit concentrated on one side, routing can remain compact where space behind the axis is limited.
