Product Description:

The MDD090C-N-030-N2M-110GR0 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for connection to digital drive controllers, the unit converts commanded current into rotary motion for automated positioning tasks in machining centers, printing lines, and material-handling axes. Its construction follows the standard housing and balancing rules for this motor family, providing a compact drive element that can be integrated wherever a 090 frame motor with a single shaft end is required for continuous closed-loop control.

At standstill, the motor can develop a continuous torque of 10.4 Nm, enabling stable holding or low-speed feed without overheating. When supplied from the drive, the rotor can reach a nominal speed of 3000 rpm, which is the base speed at which rated torque is available. Feedback to the controller is provided through digital servo feedback (DSF), and absolute position data are delivered by the integrated multiturn absolute encoder, allowing homing-free startup. The flange uses a centering pilot of 110 mm, which aligns the stator with adjoining machine frames and helps minimize radial runout.

All electrical power and signal leads exit on the right side because the connection hardware is a top-locking connector, which helps simplify cabinet routing when multiple axes are stacked. The motor has length code C, giving a rotor and stator stack that achieves the declared torque without extending the 090 frame beyond standard mounting depth. The output uses a plain shaft with a shaft seal, which helps guard the journal against coolant spray while supporting backlash-free coupling. The design omits a blocking brake, so external mechanical holding devices must be used whenever power-off torque retention is required.
