Product Description:
The MDD090B-N-030-N2M-110PR1 is a synchronous servo motor engineered by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for direct coupling to digital drive controllers, the unit converts electrical command signals into precise shaft motion suited for positioning axes, packaging machinery, and general automation lines. Its standard housing, balancing scheme, and shaft details follow length code B in the size 090 frame, supporting consistent installation in multi-axis assemblies. The motor is intended for controlled rotary motion where repeatable acceleration, stable speed control, and accurate stopping are required during cyclic machine operation.
At the mounting face the motor offers a centering diameter of 110 mm, which helps align the housing with the machine frame. Power and feedback conductors exit on the right side, which can simplify cable routing inside narrow cabinets. A sealed circular connector handles the electrical interface and helps maintain the stated protection level. A shaft seal around the output end keeps lubricant inside and limits dust ingress. During static load, the electromagnetic package sustains 7.2 Nm of continuous torque, while the rotor can reach a synchronous speed of 3000 rpm under rated current. An integrated multi-turn absolute encoder records angular position over multiple revolutions and supports position retention after power cycling. Because the encoder tracks revolutions internally, the connected controller can recover axis position more directly after a restart.
A blocking brake is fitted and supplies 6.5 Nm of holding torque so suspended or vertical axes remain secure when power is removed. Feedback is provided through digital servo feedback (DSF), giving the controller high-resolution speed and position information for closed-loop regulation. The output shaft uses a keyway to transmit torque to pulleys, couplings, or gearboxes without slip. The rotor is supplied without a side B shaft end, so the motor has only one usable shaft extension. This arrangement is suitable for axes that must hold position during stops while still using a positive mechanical connection at the load side.
