Product Description:

Bosch Rexroth Indramat manufactures the MDD090B-N-030-N2L-110PR2 as part of its MDD Synchronous Motors series. This motor is built for digital drive controllers used in automated machinery, where it converts the drive's electrical commands into controlled rotary motion. By pairing with encoder feedback and drive electronics, the unit provides repeatable torque and speed profiles required for pick-and-place axes, packaging spindles, or similar position-regulated stations in industrial production lines. Its integrated blocking brake keeps loads stationary during power removal, simplifying vertical or safety-critical assemblies.

The motor supplies a continuous standstill torque of 7.2 Nm, enabling it to hold tooling or conveyor sections without motion until commanded. During operation, it reaches a nominal speed of 3000 rpm, a rating that aligns with common direct-drive requirements. Position retention during an emergency stop is handled by its integrated brake, which can resist up to 11.0 Nm. Mechanical centering during mounting is simplified by a 110 mm centering diameter that aligns the stator to machine frames. Power is transferred through a shaft with a keyway, which helps prevent slippage between the shaft and the coupled load.

Dynamic accuracy is supported by standard balancing, which avoids the need for additional counterweights in typical speed ranges. Electrical and feedback terminations are located on the right side, and a single multipole connector carries phase power, encoder signals, and brake conductors to simplify wiring. The unit uses a standard housing for size code 090 and length code B. A shaft seal limits contamination at the front bearing, while the shaft end remains single-sided to reduce overhung mass. Digital servo feedback (DSF) transmits absolute position data to the drive for closed-loop control.
