Product Description:

The MAC090C-0-GD-2-C/130-A-1/S012 is an AC servo motor built by Bosch Rexroth Indramat and placed in the MAC AC Servo Motors series. It is intended for positioning and velocity loops driven by analog amplifiers in machine tools, packaging stations, and automated transfer axes. The unit converts three-phase electrical power into precise rotary motion, providing stable speed and repeatable torque where continuous axis response is required. Because the motor belongs to the MAC platform, it also fits installations that continue to use established analog motion hardware.

Its mechanical interface includes a centering diameter of 130 mm, allowing the housing to align accurately with standard flange bores and maintain concentricity under load. Heat generated in the stator is dissipated by natural convection, eliminating the need for external fans or liquid circuits and keeping the motor layout simple. Classified as a motor for analog drives, it expects continuous voltage or current commands rather than digital fieldbus telegrams, so it pairs directly with legacy Indramat drive cards. The GD winding code sets the phase resistance and inductance used for correct current regulation. For streamlined cabinet wiring, three-phase power exits through a connector on side A, keeping the motor, controller, and cable entry on the same machine face. This arrangement helps keep cable routing orderly when the motor is mounted with limited clearance around the rear housing.

An integrated blocking brake secures the shaft when the supply is de-energized, helping prevent load drift on vertical or suspended axes. Speed feedback is provided through tacho feedback, which sends an analog velocity signal to the drive amplifier for closed-loop regulation during acceleration, steady running, and deceleration. The specified tacho quality is adequate for most general-purpose motion profiles used with Bosch Rexroth Indramat MAC control hardware. The brake and feedback combination allows the axis to hold position at rest while still providing an analog speed reference during operation.
