Product Description:

The MDD090C-N-020-N2L-110GB0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for pairing with digital drive controllers, it delivers commanded torque and velocity to automated axes used in handling, printing, and light machining equipment. A standard housing and balancing class simplify mechanical integration, while the digital servo feedback element sends precise rotor position data to the drive for closed-loop motion control without an external encoder. Its synchronous design also supports accurate response to changing load commands during positioning and speed control.

This motor supplies a continuous standstill torque of 10.4 Nm, giving machinery adequate holding and low-speed driving force without thermal overload. Under rated excitation, it reaches a nominal speed of 2000 rpm, which is the top continuous operating speed before field weakening is needed. A centering diameter of 110 mm aligns the motor in mounting bores to help maintain concentricity between the motor and the load. The motor has a frame size of 090 and a length code of C. This combination corresponds to the stator dimensions used in this motor. Standard dynamic balancing helps reduce residual vibration across the usable speed range and supports stable feedback signals.

Cabling is routed on side B through a keyed circular connector that carries power and encoder lines in one assembly. A plain shaft transfers torque directly to couplings, and a shaft seal is fitted to limit lubricant egress or dust ingress at the bearing journal. The motor is supplied without a blocking brake, so any static load holding must be handled by the drive or by external mechanical locks. The keyed connector helps keep the electrical connection aligned during installation. By combining motor power and feedback conductors at one connection point, the cable layout stays compact around the rear housing.
