Product Description:

The MDD090B-N-020-N2L-130PB1 is a brushless AC servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed to work with digital drive controllers, it converts commanded current into precise rotary motion for positioning axes and feed drives in factory automation, where stable response and repeatable motion are needed throughout continuous machine cycles. This operating mode suits transfer units, indexing tables, and feed mechanisms that depend on consistent axis motion during frequent starts and stops. Its standard housing and single keyway shaft make it suitable for general-purpose machine frames, and the synchronous motor design supports accurate speed regulation as the drive corrects for changes in commanded load.

Its mechanical envelope uses a centering diameter of 130 mm, and electrical terminations are arranged on side B, where a sealed connector carries phase power and feedback lines in a compact connection layout. Under rated conditions, the rotor can deliver a continuous standstill torque of 7.2 Nm without exceeding winding temperature, and commanded motion reaches a nominal speed of 2000 rpm for typical servo-axis operation. The shaft has no secondary extension, and the keyway transmits torque to the coupled load while the centering pilot helps maintain accurate alignment between the motor and the driven mechanism. Keeping the power and feedback connections in one sealed interface also supports orderly cable routing where installation space is limited.

For static holding, a blocking brake supplies 6.5 Nm of torque and engages automatically when drive power is removed, which helps the axis remain in place during stops or power-off conditions. A durable shaft seal surrounds the output journal to limit dust or coolant ingress during washdown cycles, and the rotor is trimmed to the standard balancing class for smooth running across the motor's normal operating range. Position control is closed through digital servo feedback, allowing the controller to track rotor angle and respond to load changes in real time. This closed-loop arrangement helps the axis maintain accurate motion during acceleration, dwell, and reversal.
