Product Description:

The MDD090C-N-040-N2L-110GR2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded currents into rotary motion for precise positioning and speed control on automated axes in industrial machinery. The design supports applications that demand fast acceleration, repeatable velocity profiles, and integrated braking capability. This makes the motor suitable for indexing tables, transfer units, and other axes that start and stop frequently.

The motor reaches a nominal speed of 4000 rpm, allowing high cycle rates on packaging or handling stations. As a frame size 090 unit, it fits the medium power range of the platform. At standstill it can deliver 10.4 Nm of continuous torque, so clamped loads remain stable without overheating. The centering diameter is 110 mm, and it provides the pilot fit between the flange and machine frame for concentric alignment and low radial runout. Power and feedback conductors exit on the right side, which can simplify cable routing where multiple axes are installed close together. A rugged circular connector provides the electrical interface, and its keyed design helps prevent wiring mistakes.

During power-off conditions a blocking brake rated at 11.0 Nm keeps the rotor locked, preventing uncommanded descent on vertical feeders or gantry axes. Motion information is returned through Digital servo feedback (DSF), enabling the controller to correct position errors within each control loop cycle. There is a shaft seal, so splash lubrication or ambient coolant cannot enter the stator air gap. A plain shaft with no side-B extension supports clamp couplings while minimizing inertial load. Standard balancing and standard housing construction further limit vibration and support smooth operation during repeated starts and stops.
