Product Description:

The MDD090A-N-020-N2M-110PL2 is a synchronous servo motor produced by Bosch Rexroth Indramat and supplied in the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts controlled current from an inverter into precise shaft rotation for positioning tasks in automated assembly, packaging, and material-handling cells. The motor integrates feedback, mechanical coupling features, and a blocking brake so it can be installed as a direct-drive actuator on a broad range of industrial axes. This arrangement supports closed-loop motion where the controller continuously corrects speed and position during operation.

With motor size 090 and the compact length code A, the unit occupies a small footprint while maintaining thermal stability through its standard housing. The centering flange measures 110 mm, allowing repeatable alignment against machine faces. Power and feedback conductors exit on the left side and are terminated through a connector, which helps keep cable routing orderly in confined installations. Rotor balancing is standard, a shaft seal protects the internal bearings, and the shaft is supplied without a side B extension. At standstill, the motor can deliver 3.7 Nm of continuous torque, and the drive regulates speed up to 2000 rpm under nominal conditions. The keyed output lets couplings and pulleys transfer torque without relying on clamp friction alone.

Closed-loop operation is achieved with an integrated multiturn absolute encoder that reports position across multiple revolutions. Its signals are formatted as digital servo feedback (DSF), providing high-resolution data to the controller and allowing immediate position recognition after power returns. For holding loads when power is removed, a blocking brake rated at 11.0 Nm is integrated behind the rotor. The shaft uses a keyway for positive torque transmission, and the sealed bearing area helps reduce the entry of dust and other contaminants. After a stop, the controller can recover position data from the encoder while the brake secures the axis until motion resumes.
