Product Description:

The MAC090C-0-GD-3-C/110-A-1/S001 is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. The unit is designed for positioning and velocity tasks in automated machinery, providing controlled rotary motion that can be tightly synchronized with external drive commands. By converting electrical energy into mechanical rotation through its permanent-magnet design, the motor forms a core actuator inside analog or digital servo loops, driving ballscrews, rotary tables, or indexing conveyors in industrial automation cells.

Within the type code, the GD winding code identifies the copper fill and impedance used so the motor can reach its intended current limits without overheating when paired with a matching drive. A 110 mm centering diameter supports flange mounting and aligns the stator with machine frames to minimize radial misalignment. Heat is removed through natural convection, eliminating the need for forced-air equipment in sealed cabinets. The feedback channel combines tacho feedback and a second shaft end, enabling speed regulation and the mounting of external encoders or mechanical couplings. Power conductors terminate through a connector on side A, simplifying cable routing when the motor is installed against bulkheads or gearboxes.

The actuator ships with a standard blocking brake that clamps the rotor whenever supply power is removed, preventing axis drift on vertical or high-inertia loads. Speed signals are derived from a generator with standard tacho quality, giving the analog controller predictable voltage-to-rpm linearity. Classified as a motor for analog drives, it integrates directly with legacy voltage- or current-controlled amplifiers that are still common on production floors. Used with Bosch Rexroth Indramat components, these holding and feedback features reduce external hardware and support brake control and stable velocity loops.
