Product Description:

The MDD093C-N-020-N2M-110GR1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded currents into precise shaft motion for positioning tables, gantry axes, and other automated equipment. The frame corresponds to size 093 and length code C, providing a mid-range power envelope for modular drives used in multi-axis systems. It is commonly applied on axes that must start and stop frequently without losing positional accuracy, especially where the drive controller handles current, speed, and position loops electronically.

Its nominal speed is 2000 rpm, meaning the rotor can maintain rated speed while staying synchronized with the drive output. Position data is returned through digital servo feedback, and the integrated multiturn absolute encoder preserves position reference through power cycles. This feedback arrangement allows the controller to track shaft position continuously during normal operation and after restarts. The flange has a centering diameter of 110 mm, so mounting fixtures are aligned concentrically to help reduce radial runout. Power, brake, and feedback leads terminate on a connector located on the right side of the stator housing, which helps when machine wiring approaches from that direction.

A blocking brake delivers 11 Nm of static holding torque to secure vertical or inertial loads when the drive is de-energized. Torque reaches the load through a plain shaft, and a shaft seal helps limit grease migration and the entry of airborne contaminants. The motor uses a standard housing with standard dynamic balancing, so it suits regular mounting arrangements in the series without special counterweights or isolation mounts. The sealed shaft end also helps protect adjacent mechanical parts from contamination during routine industrial use.
