Product Description:

The MAC090C-0-KD-1-B/110-A-0/I01250 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is deployed on closed-loop motion axes where precise velocity and torque regulation position tooling, conveyors, and process equipment inside automated cells. By combining a permanent-magnet rotor with electronic commutation, the unit translates analog drive commands into controlled mechanical rotation suited to medium-inertia loads in continuous production.

Its electrical variant is identified by the winding code KD, which is associated with the rated voltage, current, and impedance used by the companion drive. A centering diameter of 110 mm provides the pilot fit that keeps the stator concentric to attached machine frames and helps minimize runout. Under rated conditions, the rotor reaches a nominal speed of 1500 rpm, balancing torque output with low audible noise for continuous duty. Heat generated in the stator is dissipated by natural convection, allowing installation without forced-air ducts. Rotor position is returned to the controller through incremental encoder feedback, enabling real-time correction of speed and position errors.

The motor is supplied with no blocking brake, so external clamping or drive torque must secure the load during power loss. Power conductors exit through a plug oriented as a connector on side A, which simplifies cable routing when the drive cabinet is mounted in line with that face. A built-in tacho generator produces 3 V/1000 rpm, furnishing the drive with an analog velocity signal that can supplement encoder data during low-speed operation. Classified as a motor for analog drives, the device interfaces directly with legacy current-loop amplifiers that regulate armature power using analog control voltages rather than digital fieldbuses.
