Product Description:

The MAC090C-0-GD-2-C/110-B-1 is an AC servo motor built by Bosch Rexroth Indramat and supplied in the MAC AC Servo Motors series. This model serves as a rotary actuator for closed-loop positioning and speed regulation on factory machinery that still relies on analog command voltages. By translating drive current into consistent shaft torque, it forms the electromechanical link between a motion controller and mechanical loads such as indexing tables, feeders, or gantry axes.

The motor has a centering diameter of 110 mm, allowing the flange to align concentrically with gearboxes or machine frames. Heat produced during operation is removed through natural convection, so no external fan or liquid circuit is required, and installation must allow unobstructed airflow around the housing. Rotor speed feedback is supplied through integrated tacho feedback, giving an analog voltage proportional to speed and enabling classic velocity loops on legacy controllers. Power conductors exit through a connector on side B, which directs cable runs away from the driven shaft for simpler routing in tight enclosures. The motor uses winding code GD, so the connected drive must match the current and resistance characteristics associated with that winding.

Operational features for older control platforms include its classification as a motor for analog drives, which supports compatibility with reference stages that process continuous command signals. A built-in blocking brake holds the load when power is removed, helping prevent back-driving on vertical or high-inertia axes during stops. Speed stability at low rpm benefits from standard tacho quality, which maintains feedback linearity within the accuracy range expected by legacy regulators. The integrated brake and feedback functions allow the motor to support analog servo systems without requiring separate external devices for those tasks.
