Product Description:

The MDD093C-N-030-N2M-110PR2 is an AC synchronous motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into proportional torque for precise position and speed regulation on automated gantries, conveyor axes, and tool changers. The unit uses a 093 frame size with a C-length stator to provide the power density needed for medium-duty continuous motion, and integrated feedback keeps the drive synchronized with the mechanical load during fast reversals and cyclic operation. This operating style suits axes that must repeat short moves accurately while responding smoothly to changing process demands.

The nominal shaft speed is 3000 rpm, suiting drivetrains tied to variable-frequency inverter output. A centering diameter of 110 mm aligns the flange to gearboxes or mounting plates, while standard ISO balancing helps limit vibration at full speed. Power and feedback leads exit on the right through a rotatable connector, which simplifies cable routing in compact cabinets and near adjacent machine structures. The output shaft has a keyway and a shaft seal that helps keep oil mist or coolant out of the bearing chamber. The motor also uses a standard housing arrangement, so it fits common industrial mounting layouts without unusual mechanical adaptations.

The motor uses an integrated multiturn absolute encoder that sends position data through Digital servo feedback (DSF) to the drive, allowing accurate closed-loop control without a homing cycle after each startup. This feedback path supports synchronized motion when the controller must compare commanded and actual position in real time. An electromechanical holding brake is fitted, and its static torque of 22 Nm helps secure vertical or suspended loads when mains power is removed. The brake is spring applied and released electrically through the right-side connector bundle. Because the shaft end on side B is omitted, external couplings attach only at the driven end, which helps maintain enclosure integrity and simplifies guarding.
