Product Description:

The MDD093B-N-020-N2M-110PL1 synchronous motor is produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current from an inverter into regulated mechanical rotation for positioning and speed-control tasks. By integrating directly with closed-loop drives, the unit maintains precise motion in assembly stations, conveyors, and other industrial axes that require coordinated multi-axis performance within compact machinery layouts. Its compact frame also supports installation where available mounting space is limited.

The motor provides a continuous standstill torque of 14.5 Nm, allowing the shaft to hold static loads without additional gearing. When the inverter excites the windings, the rotor can reach a nominal speed of 2000 rpm, which is the sustained operating speed for the motor. A mechanically coupled blocking brake applies 11 Nm of holding torque to keep the axis fixed during power-off or emergency stops. Position information is generated by an integrated multiturn absolute encoder, allowing the drive to recover the exact shaft angle after power is restored. The encoder communicates through digital servo feedback (DSF), so the controller receives high-resolution data for tight velocity and torque loops while minimizing electrical noise over the feedback channel.

A centering diameter of 110 mm aligns the flange with adjoining machine surfaces, and the connections are located on the left side so power and feedback cables can be routed away from moving components. The motor uses sealed connectors and a standard housing with factory balancing. The shaft uses a keyway shaft and includes a shaft seal to help limit the ingress of fluids or dust. Size code 093 and length code B identify the motor frame and active stack length. The standard shaft end omits a secondary side-B stub, which helps conserve installation space.
