Product Description:

The MDD090A-N-020-N2L-130PR0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts controlled electrical energy into precise rotary motion for automated indexing tables, gantry axes, and pick-and-place stations in industrial automation. Its synchronous design supports stable speed regulation and repeatable positioning when the drive continuously corrects for load changes.

This model uses standard rotor balancing to reduce residual vibration, and its centering pilot is 130 mm for repeatable flange alignment. A continuous standstill torque of 3.7 Nm indicates the static torque the motor can deliver without overheating. Position feedback is supplied through digital servo feedback (DSF), which sends rotor data to the drive for closed-loop control. The power and encoder conductors exit on the right side, and a removable connector simplifies field wiring. Standard housing construction protects the stator windings, while the A-length frame keeps the motor depth short for compact machine layouts. This arrangement is useful where available mounting space is limited around carriages, guards, or gearbox plates.

The rated speed is 2000 rpm, so commanded acceleration should remain within the available current of the connected drive. Because the motor is supplied without a blocking brake, external holding measures are required when shaft locking during power-off is needed. The size code 090 matches accessories sized for this frame diameter, and a hardened keyway shaft transmits torque while helping prevent slip under cyclical loads. A factory-installed shaft seal limits oil ingress along the servo flange and helps protect the bearing area from contamination. The standard shaft end on side A avoids added overhung weight on the rear bearing, which helps maintain smooth rotation in normal service.
