Product Description:

The MDD090C-N-020-N2M-130PB0 is a synchronous AC motor manufactured by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Paired with digital drive controllers, it delivers commanded torque and speed to indexing tables, gantry axes, and material-handling equipment without requiring external position hardware at the machine output. Its integrated feedback and mechanical interfaces support controlled acceleration, reversing, and repeatable positioning in automated motion systems. This arrangement suits axes that require smooth low-speed motion, consistent cycle timing, and stable closed-loop response during frequent starts and stops.

It generates a continuous standstill torque of 10.4 Nm, giving the axis steady holding capability at zero speed within the rated thermal range. Under normal excitation, the rotor reaches a nominal speed of 2000 rpm, providing a suitable operating point for common servo applications. A centering diameter of 130 mm is provided on the flange to locate the frame accurately against adjoining machine parts. Cables exit on Side B through a plug-in connector, which helps keep the opposite face clear in compact installations. The integrated multi-turn absolute encoder sends absolute position data over multiple shaft revolutions, so the controller can establish axis position immediately after power-up. The length code C housing increases active motor length within the 090 frame size, which supports higher torque density without changing the basic mounting footprint.

Position data are transferred through digital servo feedback (DSF), enabling high-resolution control loops and precise velocity regulation during changing load conditions. A shaft seal helps protect the internal bearings from dust and coolant, and the output shaft uses a keyway for positive torque transmission to a mating element. The motor is supplied without a blocking brake, so any load-holding function must be provided by drive torque or an external locking device. Standard dynamic balancing reduces vibration during acceleration, and the opposite shaft end remains blank as part of the single-ended shaft arrangement. The motor also has a standard housing finish that matches common industrial mounting surfaces.
