Product Description:

The MAC090C-1-GD-4-C/110-A-1/WI542LX/S005 is an AC servo motor built by Bosch Rexroth Indramat within the MAC AC Servo Motors series. The unit serves as the primary rotary actuator in automated production stations where coordinated motion, repeatable positioning, and rapid reversals are required. When paired with a compatible analog drive, it converts commanded current into proportional torque, allowing machine controllers to run indexing tables, gantry axes, or tool spindles with accurate motion. This operating principle makes the motor suitable for machinery that needs steady speed regulation during continuous travel and quick response during short positioning moves.

Its mechanical interface uses a 110 mm centering diameter that aligns the flange to gearboxes or mounting plates without bushings. Thermal management is handled by axial surface cooling, and an auxiliary blower running at AC 230 V moves air along the housing ribs to keep temperature within limits during continuous duty. A standard blocking brake holds position when the drive is disabled, which is useful on vertical or load-bearing axes. Electrical power reaches the stator through a connector on side A, and the output shaft includes a shaft seal that helps limit lubricant loss and dust ingress.

The GD winding code identifies the electrical winding used in this motor, so it matches legacy analog amplifiers without retuning. Position data is supplied by an incremental encoder with standard mounting, and the internal tacho can also support routine speed supervision when high-resolution feedback is not required. Control electronics can process tacho feedback, incremental encoder, or absolute encoder signals, which gives the system flexibility during retrofit work or mixed-control installations. Because it functions as a motor for analog drives, the model suits production cells that rely on ±10 V command interfaces yet still need dynamic servo performance.
