Product Description:

The MAC090C-0-GD-4-C/110-A-0/WI524LX is a rotary servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It serves as an electromechanical actuator that pairs with analog velocity and position controllers to drive automated machinery with repeatable accuracy. Integrated speed and position feedback gives the controller the signals needed for closed-loop regulation, allowing the motor to maintain commanded motion profiles under varying load conditions. This operating approach suits indexing axes, feed systems, and other machine movements that require stable response at changing speeds.

This model is built on a 90 mm frame and uses a centering diameter of 110 mm, which simplifies alignment with gearboxes or machine plates. Heat generated in the stator is dissipated by natural convection, so no external blower is required in typical cabinet installations. The three-phase power leads exit through a keyed connector on side A, keeping service access on one face of the machine. Winding code GD identifies the electrical winding arrangement used for current, resistance, and back-EMF behavior. For position feedback, the motor uses an integrated incremental encoder that returns quadrature signals to the controller. The compact housing supports installation where motor length and connector direction affect nearby guards or coupling components.

The unit is supplied without a blocking brake, so holding torque during power-off states must be provided by the mechanical system or the drive itself. Tacho calibration is rated as standard, indicating the usual accuracy band over the motor's speed range. Position feedback hardware is mounted in the standard flange, which keeps the mechanical arrangement consistent with common MAC series installations. Because it is intended for analog drives, the motor's feedback and power interfaces match legacy control hardware while still supporting precise motion in retrofit equipment.
