Product Description:

The MAC090C-0-GD-4-C/110-A-1/WI578LV/S001 is an AC servo motor produced by Bosch Rexroth Indramat and placed within the MAC AC Servo Motors series. It works with legacy analog drive systems that convert reference voltages into torque commands for closed-loop axis control in packaging machines, printing presses, and material-handling gantries. Designed for installation on a precision reference face, the unit transmits rotational motion to a matched gearbox or direct-drive load while encoder feedback returns position data to the controller.

The rotor seats against a centering pilot of 110 mm, allowing repeatable alignment on metric mounting flanges. Inside the laminated stack, copper windings follow code GD. This resistance and inductance combination matches drive amplifiers that supply the rated current without magnetic saturation. Heat is dissipated by natural convection, so no external blower or liquid circuit is required. Power leads exit through a connector on side A, which keeps cable routing on the same face as the motor cooling fins and helps reduce bend stress. For velocity or position loops, the unit uses tacho feedback with an incremental or absolute encoder, supporting compatibility with existing regulator hardware.

A standard blocking brake is fitted to keep the load motionless whenever the drive is disabled, which is useful on vertical axes that must not drift. Command accuracy relies on the shaft-mounted sensor specified as an incremental encoder with standard mounting, giving predictable servo stiffness across the speed range. Speed linearity is supported by the standard tacho quality rating, which keeps ripple within limits required for wrinkle-free web handling. The unit is classified as a motor for analog drives, so it pairs directly with earlier MAC transconductance amplifiers without protocol conversion.
