Product Description:

The MAC090C-0-KD-3-C/130-B-2/S029 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Intended for axis control on analog drive amplifiers, the motor converts electrical command signals into precise rotary motion for assembly lines, packaging equipment, and other automated machinery. By integrating a tachogenerator and a second shaft end, the unit supplies real-time speed feedback to the drive while also providing a mechanical takeoff for auxiliary devices. This arrangement supports closed-loop industrial automation tasks.

Its centering collar measures 130 mm, providing a stable reference surface that aligns the flange on precision gearboxes or machine frames. During continuous operation, the rotor is rated for a nominal speed of 1500 rpm, a value that helps keep vibration low in typical applications. Heat is removed solely by natural convection, so the housing fins must remain unobstructed to maintain thermal balance. A heavy-duty blocking brake is mounted at the rear to lock the shaft when power is removed, safeguarding vertical or indexing loads. Electrical behavior follows winding code KD, which sets the phase resistance and inductance expected by analog servo amplifiers.

Power is delivered through a single connector on side B, allowing cable routing away from the load side of the machine. Speed information comes from a configuration with tacho feedback and a second shaft end, and the additional shaft permits coupling to an external encoder or mechanical counter. The generator produces 3 V/1000 rpm, a scaling compatible with legacy velocity loops in analog regulators, and its tacho performance is marked as standard quality. Classified as a motor for analog drives, the device eliminates the need for digital fieldbus interfaces while still supporting closed-loop motion.
