Product Description:

The MDD090B-N-020-N2M-110PB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended to drive mechanical axes through closed-loop control, providing repeatable motion in packaging lines, transfer stations, and material-handling equipment. The unit interfaces directly with Indramat digital drive controllers that regulate current and velocity. That control arrangement helps the axis maintain stable motion when load conditions change during acceleration, deceleration, and positioning.

Its mechanical core is rated for a continuous standstill torque of 7.2 Nm, allowing the axis to hold tooling or payloads without overheating when the rotor is locked. Under rated excitation, the motor reaches a nominal speed of 2000 rpm, which suits low-speed, high-torque positioning tasks in indexing tables and transfer mechanisms. A centering diameter of 110 mm aligns the flange to gearboxes or machine frames for concentric mounting, and torque is transmitted through a keyway shaft to reduce the risk of slip during repeated reversals. Position tracking is provided by an integrated multi-turn absolute encoder, so the controller can retain angle and turn-count information after a power interruption.

Feedback signals are carried through Digital servo feedback (DSF) wiring in a molded connector, and the connector is mounted on Side B to keep the cable bundle away from the driven load. Dynamic forces are reduced by standard balancing, which helps the motor run smoothly at commanded speed. A factory-installed shaft seal helps protect the internal bearings from dust or coolant exposure during normal machine operation. The motor is supplied without a blocking brake, so any holding force at standstill must come from the drive or an external mechanical lock. Its B length gives the housing a moderate axial size, and the single-ended shaft layout leaves no second output on side B.
