Product Description:

Bosch Rexroth Indramat built the MDD093C-N-020-N2M-110PB1 for use within its MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it delivers regulated torque for coordinated axes in machining cells, material-handling lines, and other automated equipment. The 093 frame size combines with internal rare-earth magnets to provide a balance of speed and inertia that suits mid-capacity tasks. This arrangement supports responsive closed-loop motion, allowing the drive to correct position and speed changes as operating loads vary during normal machine cycles.

The motor’s nominal operating speed is 2000 rpm, which gives the rotor a stable rated running speed under normal load conditions. A blocking brake rated at 11 Nm is built in, and it clamps the shaft during shutdown so vertical or static loads remain stationary. Position feedback is supplied by an integrated multi-turn absolute encoder, allowing the drive to receive shaft position data after power returns without a homing cycle. All power, feedback, and brake lines exit on side B through a sealed connector, which helps keep cable routing compact inside enclosed machine spaces.

The centering pilot has a diameter of 110 mm, which helps seat the motor accurately against matching flanges or gearbox faces. Torque is transmitted through a shaft with a keyway, and a shaft seal is fitted to help limit the entry of coolant or dust. Feedback signals are provided as digital servo feedback (DSF), making the motor suitable for compatible Rexroth drive controllers that use this feedback format. The electromagnetic stack uses length code C, indicating the longer active core used in the 093 frame. Standard balancing and housing support direct mounting, and the design omits a rear shaft extension to reduce overhung load on connected components.
