Product Description:

The MAC090C-0-GD-4-C/110-A-0/GR277/S001 is an AC servo motor built by Bosch Rexroth Indramat as a member of the MAC AC Servo Motors series. It serves as a rotary actuator in industrial automation lines. The motor supplies torque and speed that are regulated by analog servo amplifiers for transfer stations, gantry axes, and packaging modules.

Its mechanical interface uses a centering diameter of 110 mm, which aligns the flange concentrically to the load side and supports repeatable shaft positioning. Heat generated in the stator is dissipated by natural convection, so the motor can operate without forced-air equipment when airflow around the housing remains unobstructed. Power conductors exit through a connector on side A, which helps simplify cable routing in tight machine frames. Electromagnetic characteristics use winding code GD, which corresponds to the resistance, inductance, and current profile used with MAC controllers for this frame size. The motor has no blocking brake, so any holding function must be provided by an external brake or by drive torque.

For feedback, the motor can be equipped with tacho feedback with an incremental or absolute encoder, allowing the analog drive to close either velocity or position loops according to the installed sensor. It uses a standard tacho assembly, which provides the accuracy needed for general-purpose motion tasks. When positional data are required, a resolver with a gear unit can be fitted to increase angular resolution for indexing applications. The overall product classification is motor for analog drives, which matches legacy MAC power stages that use ±10 V command signals rather than digital fieldbus control. This arrangement supports integration in existing systems that rely on analog command structure and conventional motor feedback.
