Product Description:

The MAC090A-1-ZD-4-C/110-A-0/WI524LV/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended for use with analog drive amplifiers that regulate current and voltage in real time to support precise positioning, indexing, and speed regulation on assembly lines, packaging machines, and material-handling axes. By translating command voltages into proportional torque, the motor serves as the electromechanical actuator in closed-loop motion tasks and helps the connected drive maintain stable response during changing load conditions.

The motor uses a centering diameter of 110 mm, which allows accurate alignment with gearboxes and mounting flanges. Thermal control relies on axial surface cooling; an external fan powered by AC 230 V moves air along the stator housing to remove heat during continuous operation. Winding code ZD is matched to legacy analog regulators, and the motor reaches a nominal speed of 1500 rpm for applications that require steady mid-range rotational performance. Position feedback is provided by an incremental encoder with standard mounting, which supplies square-wave signals for the speed loop, while the built-in tacho generator supports systems that still use voltage-based velocity feedback.

The velocity tacho produces 3 V/1000 rpm, giving the controller a linear signal that tracks shaft speed and supports stable regulation at low and moderate operating speeds. Power conductors connect through a connector on side A, which helps simplify cable routing and keeps the motor connection layout straightforward inside compact machine spaces. Because the motor is supplied without a blocking brake, holding torque at standstill must be provided by the drive or by an external mechanical device. This arrangement is common on axes where the load does not need a dedicated holding function after motion stops.
