Product Description:

The MAC090C-0-GD-4-C 110-A-2 AC servo motor is produced by Bosch Rexroth Indramat in the MAC AC Servo Motors series. It serves as a rotary actuator that delivers commanded torque and speed to mechanical axes controlled by analog drive amplifiers. By translating regulated three-phase currents into shaft rotation, the unit serves as a primary motion element in automated machining centers, pick-and-place gantries, and material-handling equipment.

A built-in heavy-duty blocking brake holds the shaft when power is removed, allowing vertical or overhung loads to remain stationary without external clamps. Thermal energy is dissipated through natural convection, so cabinet layouts must provide adequate airflow around the housing. The mounting interface includes a centering recess of 110 mm, which aligns the flange accurately on faceplates and supports repeatable concentricity. Mains conductors enter through a connector on side A, simplifying cable routing when the motor is installed with the shaft pointing forward. Internal stator wiring follows winding code GD; this code corresponds to the motor’s back-EMF constant and nominal current so the paired analog drive can be configured with matching voltage and current limits.

Velocity feedback is available through tacho feedback with an incremental or absolute encoder, giving the analog controller a direct speed signal for closed-loop regulation and optional position information for coarse homing routines. The unit’s tacho accuracy is classified as standard, which is sufficient for general motion axes that do not require sub-arcminute precision. As a motor for analog drives, it relies on external velocity and current loops rather than embedded digital electronics. That layout suits legacy control cabinets that use established analog motion hardware.
