Product Description:

The MDD090B-N-020-N2M-110PB2 is a brushless synchronous motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed to work with digital drive controllers, it converts electrical command signals into precise rotary motion for automated conveyors, tooling spindles, and pick-and-place modules. Its embedded feedback supports closed-loop operation where repeatable speed and torque are required. Such motion profiles are common in compact servo axes used for automated handling equipment.

Under continuous stall conditions, the rotor can deliver 7.2 Nm without exceeding thermal limits, which is the steady-state torque available for holding or slow-feed tasks. During motion cycles, the shaft can reach 2000 rpm, a nominal speed that suits mid-range gearboxes in assembly machinery. Mechanical alignment uses a 110 mm centering diameter, and torque is transmitted through a keyway shaft. Power and feedback conductors exit on Side B, which helps keep connectors clear of adjacent equipment. The motor uses a circular connector for the electrical connection. It also has standard balancing, a standard housing, motor length code B, and size 090, while the drive-side shaft end helps keep the coupling arrangement compact.

In applications that require secure parking, the built-in blocking brake supplies 11.0 Nm of static torque when engaged. Real-time position data are transmitted by Digital servo feedback (DSF) through an integrated multiturn absolute encoder, allowing the controller to retain position information across multiple revolutions. A molded shaft seal helps keep dust and process fluids away from the bearings. The integrated brake and encoder reduce the need for external devices around the motor body. This layout keeps the package compact and supports clean cable routing in enclosed machine spaces.
