Product Description:

The MDD090B-N-020-N2L-110PB0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is supplied as a motor for digital drive controllers and is intended to deliver closed-loop torque and speed control in machine tools, handling modules, and assembly stations. The unit’s mechanical interfaces, encoder system, and shaft configuration allow straightforward integration with compatible drives for precise positioning tasks in industrial automation cells.

At standstill, the motor can provide a continuous torque of 7.2 Nm, so a drive can maintain load forces without thermal overload during static holding periods. Its nominal mechanical speed is 2000 rpm, which suits applications that balance moderate velocity with high positioning accuracy. A centering diameter of 110 mm simplifies locating the flange on gearboxes or mounting plates and supports concentric alignment. Power and feedback conductors exit on side B of the housing, and the round industrial connector interface allows cable connection without opening a terminal box. Standard rotor balancing minimizes residual vibration, and the B-length stator package supplies the listed torque while keeping overall motor mass low.

The design omits internal holding hardware, and it is supplied without a blocking brake, so external clamping or drive torque must secure vertical loads when power is removed. Position feedback is handled by digital servo feedback, allowing the controller to monitor rotor position during closed-loop operation. The output shaft uses a keyway and is supplied with a shaft seal to help limit contaminant ingress and lubricant escape. A standard housing, size 090 frame, and a single-ended shaft simplify coupling to belt pulleys or gear reducers, while the opposite side remains free for tight installation spaces.
