Product Description:

The MDD090B-N-020-N2L-110PL1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Built for digital drive controllers, it converts controlled current from an amplifier into rotary motion for axes that need repeatable positioning and steady speed regulation in industrial automation cells, gantries, and material-handling stations. Its standard housing and integrated feedback allow the motor to mount directly to machinery while maintaining closed-loop performance under variable load conditions. This arrangement supports consistent motion on indexing, transfer, and feed axes that must start, stop, and reverse without losing control accuracy during repetitive duty.

This model delivers a continuous standstill torque of 7.2 Nm, enabling stable holding or low-speed creep without overheating. When commanded to run, its rotor reaches a nominal velocity of 2000 rpm, which suits common gear ratios in packaging and transfer applications. Rotor position is returned to the drive through digital servo feedback (DSF), allowing the controller to correct error during each control cycle. Electrical and signal conductors terminate on a single connector, and the cable exit is oriented to the left side for cleaner routing on line-side installations. The motor is balanced to a standard grade, and a shaft seal helps keep contamination away from the bearing region.

For vertical axes or emergency stops, the motor is supplied with a blocking brake that exerts 6.5 Nm of torque when power is removed. Motion is transferred through a hardened steel shaft with a keyway, and the design omits a shaft end on side B to reduce overall length. Precise alignment during assembly is assisted by the 110 mm centering diameter formed into the flange. The motor uses frame size 090 and length code B, which provide a predictable mounting footprint across the series while preserving the standard housing form.
