Product Description:

The MAC090C-0-GD-1-B/110-A-0/J1250/S01 is an AC servo motor designed for closed-loop positioning tasks in industrial automation. It belongs to the MAC AC Servo Motors series manufactured by Bosch Rexroth Indramat. Within a drive system, the motor converts drive-generated current into controlled rotary motion so actuators, spindles, or feed rollers can track command signals with high accuracy. That operating behavior supports repeatable starts, stops, and speed changes on machines that depend on coordinated axis motion.

The flange features a centering diameter of 110 mm, allowing precise seating on gearboxes or machine plates without additional alignment bushings. Heat produced by the stator is removed through natural convection, so no external blower or liquid circuit is required. Rotor position is detected by incremental encoder feedback, enabling the drive to calculate speed and displacement from pulse counts for rapid servo corrections. The stator uses a GD winding, which identifies the coil impedance and voltage constant used to match the motor with a compatible current range. This combination of feedback and winding data helps the drive maintain smooth response during load changes and directional reversals.

The power leads exit through a connector on side A, an orientation that can help keep power and feedback wiring separated inside energy chains or cabinet runs. When paired with a drive amplifier, the unit serves as a motor for analog drives, responding to ±10 V velocity or torque commands instead of digital fieldbus messages. This control method suits systems that use analog reference signals for speed or motion regulation. The shaft is delivered without a holding brake, so vertical loads must be secured by an external clamp or by the drive's torque-holding capability when power is removed.
