Product Description:

The MDD090C-N-030-N2L-130GB0 is produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it supplies closed-loop torque and speed for automated axes in positioning, indexing, and feed applications. The C length code and 090 frame size set its mechanical envelope, while the standard housing and standard balancing suit general machine installations. This motor type is intended for precise motion duties where the drive continuously corrects speed and position under changing load conditions.

The motor uses a centering collar with a 130 mm diameter to support coaxial alignment with flanges or gearboxes. Power and feedback lines exit on Side B, and the factory-mounted Connector allows cable connection without opening the housing. At standstill, the motor can deliver 10.4 Nm of continuous torque, which helps determine inverter current sizing for static positioning tasks. Because the design ships without a blocking brake, holding force must be provided by the drive or an external clamp when power is removed. This layout keeps the cable exit concentrated on one side of the housing and leaves the mounting face unobstructed. Standard balancing helps reduce vibration during operation, and the shaft end is supplied in the standard form without an auxiliary stub on the non-drive side.

Control precision relies on Digital servo feedback (DSF), which returns high-resolution position data to the controller for commutation at a nominal speed of 3000 rpm. A plain shaft transmits torque directly to couplings, and the motor uses a shaft seal around the journal for added ingress protection. The feedback system supports accurate rotor angle detection during starting, low-speed motion, and sustained running. The encoder and stator windings are housed within the motor frame, while the exterior fin structure supports heat dissipation during operation. The connector orientation does not alter the housing arrangement, and the motor remains suitable for digitally controlled axes that require stable feedback.
