Product Description:

The MDD093C-N-040-N2M-110GA1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it supplies precise torque and speed control for machine tools, packaging lines, and handling modules. This version carries length code C and is factory balanced to the standard grade, allowing direct coupling to compliant loads without additional correction. A standard housing encloses the stator, and power as well as feedback lines are connected through a single coded connector. The rotor has a single shaft end, simplifying mounting to couplings or pulleys.

The motor’s nominal speed is rated at 4000 rpm, meaning the rotor can rotate 4000 times per minute under rated electrical and thermal conditions, a figure used when matching mechanical transmission ratios. A centering diameter of 110 mm provides the reference surface that aligns the motor face to the machine frame, helping keep shaft runout within tolerance. A blocking brake is integrated, and it can hold the shaft stationary with a torque of 11 Nm when power is removed, preventing load drift on vertical axes. Position feedback is supplied by an integrated multi-turn absolute encoder, and its signals are processed through digital servo feedback (DSF) for closed-loop control down to a single increment.

A shaft seal is fitted at the front of the stator, so lubricant from the driven machine cannot migrate into the bearing cavity during washdown cycles. Power and feedback connectors point toward Side A, allowing cable trays to remain on a single side of the cabinet. The motor belongs to frame size 093, giving a flange pattern and mass compatible with other drives in the same diameter class. A plain shaft enables backlash-free clamping with standard hub couplings without the need for keyways or splines.
