Product Description:

The MDD090C-N-020-N2L-110GA0 synchronous motor is built by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Supplied for use with digital drive controllers, the unit converts commanded current profiles into accurate rotary motion for positioning tasks on tooling, indexers, and conveyor sections in automated plants. Its 090 frame with C length offers a compact installation footprint while still supporting the torque and speed response expected in medium-duty servo applications. This layout makes the motor suitable for machines that need reliable axis control without requiring a large mounting envelope.

The motor delivers a continuous standstill torque of 10.4 Nm, so a drive can hold loads during short process pauses when no mechanical brake is required. Under rated excitation it reaches a nominal speed of 2000 rpm, giving a balanced mix of feed velocity and servo stiffness for general motion tasks. A centering diameter of 110 mm helps align the housing accurately on the machine interface and supports consistent coupling geometry. Position data is returned through digital servo feedback, allowing closed-loop operation with precise speed and position control. The rotor uses a plain shaft, which suits direct coupling to pulleys or flexible couplings where a keyed connection is not needed.

Cabling is routed toward the non-drive end because the power and feedback plugs are mounted on side A and are supplied through a single industrial connector, which helps keep cable routing orderly in compact enclosures. For environmental protection, the front bearing region is supplied with a shaft seal, which helps limit dust ingress and lubricant migration during operation. The motor is supplied without a blocking brake, so any vertical axis must hold the load through external means or continuous drive torque. Standard dynamic balancing and a standard cast housing help maintain smooth running in normal industrial service. A single-ended shaft arrangement with no rear shaft extension also leaves the back of the motor clear for nearby components and airflow.
