Product Description:

The MAC090C-0-KD-3-C/110-A-1 is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Designed for analog drives, it converts controller signals into precise shaft rotation for positioning and speed control in industrial automation. Its mechanical and electrical interfaces follow the MAC series layout, allowing straightforward installation in established motion systems. This type of motor is suited to axes that require stable speed regulation and repeatable rotary motion during normal machine operation.

Mechanical and thermal limits govern continuous operation. The motor mounts through a centering flange of 110 mm, which keeps the stator concentric with coupled machinery. Heat is removed solely by natural convection; no fan or external coolant is provided, so mounting space must allow free airflow around the housing. Under nominal excitation, the rotor reaches 1500 rpm, a speed matched to analog drive regulators. The electromagnetic system uses winding code KD, which corresponds to resistance and inductance values that the controller must accommodate during current regulation. Velocity feedback is supplied by an internal tachogenerator that produces 3 V/1000 rpm, and the standard tacho quality supports general motion duties. Because cooling is passive, the motor is best installed where surrounding air can circulate without obstruction.

Power conductors are routed through a connector on side A, allowing rigid cabinet wiring while keeping service access clear on the opposite face. The rotor is extended on the non-drive end, and the unit includes tacho feedback and a second shaft end so an additional encoder or mechanical load can be fitted without altering the primary coupling. A standard blocking brake holds the shaft when the drive is disabled, helping prevent drift on vertical or unbalanced axes. The rear shaft extension can also support auxiliary mechanical connections where the machine layout requires access at both ends of the motor.
