MAC090C-0-GD-4-C/110-A-0/WA612XX

The MAC090C-0-GD-4-C/110-A-0/WA612XX is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It serves as a rotary actuator in industrial automation, converting command signals from a servo drive into controlled torque and precise angular displacement. A permanent-magnet rotor, laminated stator core, and integrated sensor interface allow the drive to regulate current in real time, making the unit suitable for positioning axes in packaging machines, handling gantries, and index tables where repeatable motion is required.

The stator winding follows code GD, establishing the electrical resistance and inductance pairings expected by the external amplifier. Mechanical indexing during installation is aided by a centering seat of 110 mm, which aligns the flange with the machine frame. Heat produced by copper losses exits through the frame via natural convection, so no separate fan or liquid circuit is needed. Power leads enter through a connector on side A, simplifying cable routing in cabinets that mount the motor with the shaft facing outward. For holding requirements, the unit is supplied without a blocking brake, so static load retention must be handled by external means.

The feedback chain completes the control loop through tachofeedback with incremental or absolute encoder signals that report velocity and position to the drive. Mounting provisions include an attachment set for position feedback, allowing the chosen transducer to be rigidly fixed in line with the shaft. Speed accuracy is supported by standard tacho quality, providing a consistent voltage-per-rpm gradient for regulation tasks. Because the motor is classified as a motor for analog drives, its sensor outputs and power terminals are directly compatible with legacy amplifiers that use ±10 V command references and analog velocity loops.
