Product Description:

The MDD093C-N-040-N2L-110PR0 is an AC synchronous motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It serves as a motor for digital drive controllers, converting controlled inverter signals into repeatable torque and velocity for packaging lines, handling systems, and other motion-centered automation cells. In these settings, the motor forms the electromechanical endpoint of a closed-loop drive and responds to encoder feedback to keep tooling or fixtures on their commanded path.

The unit’s nominal speed is 4000 rpm, allowing fast cycle times where high spindle or axis velocities are required. A centering diameter of 110 mm aligns the flange with machine frames and helps preserve concentricity during installation. Position data are transmitted through digital servo feedback, so the drive can correct load-induced position errors in real time. Power and feedback leads exit on the right side, which can simplify cable routing when the cabinet is placed on that side of the machine bed. The output shaft is machined with a keyway to provide positive torque transmission to pulleys or couplings without relying only on friction. A molded connector carries both phase conductors and low-level signals, which reduces the number of separate lead terminations.

The motor carries a length designation of C, giving it a deeper stator core than shorter variants and increasing continuous torque capacity. Its frame size is 093, which places it within the corresponding mechanical envelope of the series. A shaft seal is fitted to help limit coolant or dust ingress at the journal, and the motor uses a standard housing that matches the family’s usual mounting form. Balancing is supplied in the standard grade for smooth running across the speed range. The design omits a holding brake, so position during power-off must be maintained by external clamping or motor torque, and the shaft end on side B remains unmachined.
