Product Description:

The MDD093C-N-040-N2M-110GB1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts electrical commands into precise mechanical rotation for positioning, indexing, and continuous-speed duties in automated machinery. The design uses a standard housing and standard rotor balancing, so it fits typical industrial frames without special vibration measures. It is intended for servo-driven packaging, indexing, and handling systems that need accurate speed and position response over repeated cycles.

Its nominal speed is 4000 rpm, enabling high-cycle axes to reach target velocity quickly while staying synchronized with the inverter frequency. A blocking brake supplies 11 Nm of holding torque to secure vertical loads when power is removed. Position data returns to the drive through digital servo feedback (DSF), supporting closed-loop control with fine position monitoring. A centering diameter of 110 mm keeps the flange aligned on the machine face, and all power, brake, and feedback conductors exit on side B for straightforward cable routing in shared cable channels. The single connector interface simplifies connection of the motor, brake, and feedback circuits.

The mechanical envelope uses size code 093 and length code C, giving the motor a longer stack for higher torque density than shorter versions in the same frame. A plain shaft without a keyway reduces runout, allows clamp couplings to be positioned anywhere along the journal, and works with a shaft seal that helps keep contaminants out of the bearing cavity. An integrated multiturn absolute encoder tracks revolutions during power loss, and the lack of a second shaft end helps keep the overall assembly depth shorter. The shorter rear profile also leaves more room behind the motor in compact machine layouts.
