Product Description:

Bosch Rexroth Indramat manufactures the MDD090C-N-040-N2L-110GL0 as part of the MDD Synchronous Motors series. This motor is built for connection to digital drive controllers. It converts commanded current into regulated torque and speed for positioning tables, handling modules, and other motion duties in automated lines. Closed-loop operation helps the axis maintain stable motion during acceleration, indexing, and steady running.

The motor delivers a continuous standstill torque of 10.4 Nm, allowing it to hold or index loads without oversizing the drive. Its nominal shaft velocity is 4000 rpm, giving a wide operating range for rapid point-to-point moves as well as steady production speeds. A centering diameter of 110 mm aligns the flange on compatible machine frames and helps maintain accurate mounting. Rotor position is returned through digital servo feedback (DSF), which provides incremental and commutation data so the controller can close high-bandwidth control loops. All power and signal conductors exit on the left side, and a single multi-pin connector keeps cable routing compact. The assembly also uses standard balancing to ISO guidelines, and the 090 frame size with C-length stator provides a compact motor body with useful thermal capacity.

The design is supplied without a blocking brake, so external holding force or drive torque must secure vertical axes during power loss. The motor uses a shaft with a shaft seal, which helps keep coolant or cutting fluids from migrating into the bearing chamber. A plain shaft transmits torque through friction couplings rather than keys, reducing local stress during high-cycle reversing service. Standard housing construction and a single-ended shaft support straightforward installation in machinery that requires accurate servo motion and consistent mechanical alignment.
