Product Description:

Bosch Rexroth Indramat manufactures the MDD093B-N-030-N2L-130PA1 synchronous motor. The unit belongs to the MDD Synchronous Motors series and is intended for integration with digital drive controllers in automation equipment. It is used as a motor for digital drive controllers. Its electromechanical design supports high-frequency position loops and repeatable velocity profiles, making it suitable for pick-and-place axes, packaging stations, and general machine tools. The motor operates as a brushless permanent-magnet actuator, delivering commanded torque while maintaining thermal stability through natural convection in typical cabinet installations and tight machine spaces.

The rotor-stator assembly is dynamically balanced to a standard grade so vibration remains minimal when the shaft produces a continuous stall torque of 14.5 Nm. When driven by a matched inverter, the motor reaches a nominal mechanical speed of 3000 rpm, allowing direct coupling to moderate-inertia loads without additional gear reduction. A centering shoulder of 130 mm helps align the motor accurately on precision mounting plates. For vertical or suspended axes, a blocking brake is integrated, and it provides 11 Nm of static holding torque after power is removed. Position data are returned to the controller through digital servo feedback (DSF), enabling closed-loop control with high resolution while avoiding analog drift.

Power and feedback conductors exit on Side A, and the motor connects to the cabinet harness through a coded connector that follows the series pinout. The motor uses frame size 093 and length code B, which keep the housing within the expected dimensions for this model. A factory-installed shaft seal helps block coolant or oil from entering the motor. The single-ended shaft is finished with a keyway so couplings can transmit torque without slip. The shaft end on side B is omitted, which helps conserve depth in confined machine frames.
