Product Description:

The MDD090B-N-020-N2L-110PL2 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts controlled current from a drive into repeatable rotary motion so that indexers, feeders, and other CNC axes can follow precise position commands within an automated cell. This description is already clear and does not require further correction.

The motor has a frame size of 090 and length code B, a combination that sets the active stack height and influences inertia. Standard dynamic balancing reduces vibration at the rated speed, while the centering pilot measures 110 mm to align the flange with gearbox or machine mounts. A standard housing encloses the stator windings and includes a shaft seal at the output journal. Drive and feedback conductors are routed through a sealed connector, which simplifies cable routing in tight cabinets. At standstill, the motor can deliver 7.2 Nm of continuous torque without exceeding thermal limits, and it can hold commanded velocity up to 2000 rpm for applications that require moderate speed with high positional accuracy.

A blocking brake rated for 11.0 Nm is mounted to the rear of the rotor and engages automatically whenever power is removed. Service wiring exits on the left side of the stator, allowing predictable harness layout inside multi-axis racks. Rotor position is reported through digital servo feedback (DSF), enabling real-time correction of torque commands issued by the controller. Power is delivered through a shaft with a keyway, which provides positive mechanical coupling to pulleys or couplings without relying only on friction. The shaft is single-ended and does not include a side-B extension, which helps save installation space.
