Product Description:

The MAC090C-0-KD-2-C/130-B-1/S003 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. As a motor intended for analog drive controllers, it converts sinusoidal armature current into precisely regulated shaft motion. In automated machinery, the unit supplies repeatable torque and position control for axes such as feeders, slides, or rotary tables that rely on continuous closed-loop feedback from the connected drive.

During installation, the motor seats against a centering shoulder with a diameter of 130 mm, which keeps the stator concentric to mating mechanical parts and minimizes runout. Heat produced by copper losses leaves the housing through natural convection, eliminating the need for auxiliary fans and simplifying cabinet airflow calculations. A resolver is not used; instead, the unit is equipped with tacho feedback, providing an analog velocity signal that the drive amplifies for speed regulation. The rotor has a nominal speed of 1500 rpm, which indicates continuous operation without exceeding thermal limits. Power enters through a plug oriented as a connector on side B, allowing cable routing away from the driven load. The product is classified as a motor for analog drives, so its control loops depend on proportional gain and external summing rather than digital fieldbus commands.

Winding code KD indicates the phase resistance and inductance that the analog amplifier must match for optimum current rise time. A standard blocking brake is integrated to hold the shaft when the enable signal is removed, preventing back-driving on vertical or unbalanced axes without adding external clamps. For the speed loop, the tachogenerator produces 3 V/1000 rpm, giving the controller a linear voltage proportional to speed and simplifying calibration because one volt corresponds to roughly 333 rpm.
