Product Description:

The MAC090C-1-GD-4-C/110-A-1 is an AC servo motor manufactured by Bosch Rexroth Indramat and supplied within the MAC AC Servo Motors series. As a closed-loop drive element, the unit converts commanded current from an analog servo amplifier into controlled shaft motion for positioning or speed regulation tasks on automated lines, packaging tables, and material-handling axes. Its electromechanical design integrates with Indramat drive packages, providing precise torque delivery and feedback for industrial automation processes that require consistent, repeatable motion.

Thermal management is supported through axial surface cooling, which moves air along the housing fins so heat conducted from the stator is transferred directly to ambient air. A built-in blower rated at AC 230 V supplies the airflow and eliminates the need for external ducting. The motor seats against a machined mounting pilot with a centering diameter of 110 mm, establishing coaxial alignment between the motor shaft and the driven load. Power conductors are terminated through a connector on side A, simplifying cable routing inside a cabinet when the drive is installed with its flange toward the machine frame. Electromagnetic behavior is tied to winding code GD, which sets resistance, inductance, and nominal current values matched to corresponding Indramat analog servo drives.

Mechanical holding is provided by a standard blocking brake that clamps the shaft when the control system removes drive power, preventing drift on vertical or load-holding axes. Motion feedback is provided by tacho feedback with an incremental or absolute encoder, enabling the drive controller to close both velocity and position loops from a single feedback channel. The unit is classified as a motor for analog drives, so its signal interfaces and electrical ratings correspond to Indramat analog controller families rather than newer fieldbus-based platforms. To confirm speed consistency, the tachogenerator is built to standard tacho quality, supporting stable velocity regulation during continuous duty cycles.
