Product Description:

The MAC090C-0-KD-2-C/130-B-0/S003 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts current from proportional amplifiers into regulated torque and speed that move indexing tables, pick-and-place heads, or printing cylinders. The design supports applications where stable mid-range rotation and straightforward passive cooling are preferred over very high-speed operation. It is suited to motion systems in which the external amplifier performs the control work while the motor supplies the rotary output.

A centering diameter of 130 mm seats the housing precisely in pilot bores, which helps minimize radial runout and improve alignment during installation. The stator winding follows code KD, a designation that indicates impedance values so analog amplifiers can supply predictable phase currents. Continuous operation is rated at 1500 rpm, a speed that matches reduction stages used in material-handling or forming equipment. Heat generated at that duty point is released through natural convection, so the enclosure must remain in free airflow but does not require a fan or liquid circuit. The unit ships without a blocking brake, so any static holding force must be provided by external clamping or drive torque.

Velocity feedback is provided by a tachofeedback device that produces 3 V/1000 rpm, letting the controller derive real-time speed with simple analog circuitry. This arrangement supports stable closed-loop speed regulation in conventional analog servo systems. The feedback element is standard, giving sufficient accuracy for general positioning while keeping the signal path uncomplicated. Supply conductors leave the stator through a connector on side B, which keeps cabling clear of the drive-end mechanical hub and shortens the path to cabinet glands. That cable direction can also help reduce interference with nearby couplings, guards, and mounting hardware around the shaft end.
