Product Description:

The MDD090B-N-040-N2L-110PR1 is a synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it transforms regulated current into precise rotary motion for automated positioning tasks found in assembly lines, pick-and-place stations, and light machining equipment. Its synchronous design supports smooth speed regulation and accurate axis response during repeated motion cycles. The unit uses a standard housing profile, and its connector-based power and feedback terminations allow cable changes without opening the motor body. This layout is useful on compact machine axes where service access is limited and consistent feedback routing is required.

At standstill, the motor can supply a continuous torque of 7.2 Nm for controlled holding under drive power. While running, it reaches a nominal speed of 4000 rpm, supporting short index times and high throughput. A centering shoulder measuring 110 mm guides the flange into mating machinery for repeatable concentricity. For load securing during power-off, the integrated blocking brake provides 6.5 Nm of static holding force. The frame corresponds to size code 090, which matches standard Rexroth mounting patterns. The motor uses a single rear connector for both phase conductors and encoder signals, and it has frame length B for the axial envelope.

The rotor uses standard balancing, which helps limit vibration as shaft speed rises during operation. All electrical leads exit on the right side, which can simplify routing in compact machine spaces. Feedback is handled through Digital servo feedback (DSF), allowing the controller to read position values directly from the encoder without extra conversion hardware. The shaft uses a keyway for positive mechanical coupling, includes a fitted shaft seal, and is supplied without a side-B extension. The shaft seal helps protect the bearing area from dust and routine splash in enclosed equipment.
