Product Description:

The MDD090B-N-030-N2M-110PB1 is a synchronous servo motor produced by Bosch Rexroth Indramat for use with digital drive controllers. As a member of the MDD Synchronous Motors series, it supplies regulated rotary actuation for positioning and velocity loops in automated machinery. The device follows the 090 frame size with length code B and serves as a compact motor for digital drive controllers in packaging, pick-and-place, and light machining cells where precise, closed-loop motion is required. Its synchronous design allows the paired controller to regulate speed and position accurately during repeated starts, stops, and direction changes. This operating role suits machinery that depends on repeatable motion over many short cycles.

The motor reaches a nominal speed of 3000 rpm, enabling direct coupling to gearless loads that demand high cyclic throughput. At standstill, it can deliver a continuous torque of 7.2 Nm, which is the sustained torque available for static holding or slow indexing without thermal overload. Mounting is simplified by a centering diameter of 110 mm, which aligns the stator to the machine plate, while the rotor uses standard balancing for smooth operation. Power and feedback conductors exit on side B through a keyed connector, a layout that keeps cable routing compact inside enclosed machine spaces. The housing uses standard fully enclosed construction, and the shaft end is provided only on the drive side to avoid a second shaft projection.

Dynamic stopping is handled by an integral holding brake that exerts 6.5 Nm of retentive torque to secure vertical or suspended loads when power is removed. Motion information is captured by a multi-turn absolute encoder and transmitted as digital servo feedback, allowing the drive to restore exact position after downtime. The feedback system also supports accurate commutation during startup and normal running. The single output shaft is machined with a keyway and protected by a shaft seal. This arrangement allows coupling to pulleys or hubs while helping keep contaminants out of the bearing cavity.
