Product Description:

The MDD093B-N-020-N2L-110PL0 is a synchronous AC servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts modulated three-phase current from an inverter into precise rotary motion, supplying feedback so the controller can close the position loop in automated assembly lines, tooling centers, and material-handling axes. Its compact frame simplifies integration in space-limited machine layouts. Integrated feedback also removes the need for separate encoder hardware, which helps reduce external wiring at the axis.

A continuous standstill torque of 14.5 Nm allows the rotor to hold static loads for extended periods without excessive thermal drift. A rated speed of 2000 rpm matches common machine-tool feed rates under nominal voltage. Precise centering on a 110 mm register seats the flange concentrically and helps reduce bearing side loads. Position accuracy is maintained through digital servo feedback, which sends high-resolution encoder data to the drive for closed-loop control. Torque is delivered through a keyway, providing positive coupling to gears, pulleys, and similar driven components.

The mechanical package uses a standard housing and standard balancing grade, which helps limit vibration transfer to adjacent machine structures. All power and feedback leads exit on the left-side connection, with both routed through a single connector to simplify cable routing. A shaft seal protects the front bearing against coolant splash and abrasive dust. Because the unit is supplied without a blocking brake, an external holding device is needed when power is removed. Frame size 093 and length code B set the stack dimensions, and the standard shaft end has no rear output stub, which helps reduce installation depth.
