Product Description:

The MDD090B-N-020-N2L-130PR0 is manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts electrical energy into regulated rotary motion for positioning tables, handling gantries, and similar automation axes. The unit uses the 090 frame size with B length, and its standard housing and balancing make it suitable for general-purpose machine installations. This layout supports servo applications that need repeatable motion and stable mechanical integration without requiring unusual mounting arrangements.

At standstill, the motor can supply 7.2 Nm of continuous holding torque, allowing it to support static loads without additional gearing. Under rated excitation, it reaches a nominal speed of 2000 rpm, matching drive systems used in moderate-speed production cycles. Power and feedback conductors exit on the right side, so wiring can remain inside the machine envelope when the stator is mounted horizontally. The single-plug connector keeps electrical connection points compact, and the encoder channel uses digital servo feedback to relay position data with high resolution for precise velocity and position control.

The flange has a centering pilot of 130 mm that aligns the stator to gearboxes or mounting plates and helps maintain accurate fit during installation. Torque is transmitted through a keyway shaft, and the drive side is fitted with a shaft seal to help limit contaminant entry and lubricant escape. The motor is supplied without a blocking brake, so static holding must be achieved electrically or with external clamps. It has a standard shaft end on side A, and there is no shaft extension on side B. That arrangement keeps the motor layout simple for compact servo axes where cable routing and coupling space must remain controlled.
