Product Description:

The MDD090A-N-030-N2L-110PR2 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts regulated drive current into precise rotary motion for positioning or cyclic-speed tasks in automated machinery. The rotor is dynamically balanced to a standard grade, and the unit uses a right-side electrical connector to simplify cabinet routing. Its housing and shaft end are supplied in a standard configuration, so no secondary shaft projects from side B.

This motor delivers a continuous standstill torque of 3.7 Nm, allowing small to medium loads to remain energized without overheating when airflow is limited. Under rated excitation, it can spin at a nominal speed of 3000 rpm, matching common drive controller outputs. Precise mechanical alignment is supported by a centering diameter of 110 mm, and the stator windings are installed in a compact frame with motor size code 090. With the connections located on the right side, the feedback and power cables exit toward the machine frame instead of upward or to the left. The motor uses length code A, which is the shortest housing length in this frame. Signal transmission uses a plug-in connector, which simplifies cable connection compared with hard-wired terminations.

A blocking brake is integrated and can hold the shaft with 11.0 Nm of static torque when power is removed, preventing drift on vertical or indexing axes. Position data return relies on digital servo feedback, so the drive can close the control loop without external encoders. Contaminant entry at the coupling is reduced by a shaft seal, and torque is transferred through a keyed shaft end with a keyway profile. The motor uses standard balancing to support smooth operation across its speed range.
