Product Description:

The MAC090A-0-ZD-4-C/110-A-1/WI522LX belongs to the MAC AC Servo Motors series manufactured by Bosch Rexroth Indramat. This rotary servo motor interfaces with analog drive controllers to provide closed-loop speed and position control for automated machinery such as indexing tables, packaging stations, and assembly axes. Its feedback arrangement lets the paired controller correct for load changes during operation, which helps maintain stable motion in repetitive machine cycles. Because the unit is intended for controlled axis service, it supports both steady running and frequent start-stop movement in automated equipment.

The motor seats against a register that measures 110 mm in centering diameter, giving the housing a repeatable fit on precision mounting surfaces. Heat is removed by natural convection, so no external blower or liquid circuit is required. Its rated operating speed is 1500 rpm, which suits smooth low-frequency torque generation in medium-inertia loads. This operating point is useful where stable torque at moderate shaft speeds is more important than a very high top-end velocity. Power conductors exit through a sealed connector on side A, which simplifies cable routing when the drive cabinet is positioned to the left of the motor shaft. The ZD winding code indicates the stator’s electrical characteristics used by the paired drive for current limiting and acceleration control.

The built-in blocking brake engages automatically at power-off to hold the shaft without additional actuators. Speed feedback linearity is maintained by a tachogenerator that outputs 3 V/1000 rpm, and its tacho quality is standard for this frame size. The unit is a motor for analog drives, so command signals are processed as continuous voltages rather than fieldbus telegrams. This interface suits motion platforms that rely on analog command and feedback channels instead of digital network control. For applications that require finer position handling, the wiring harness also supports incremental or absolute feedback signals in addition to tachometer feedback. That arrangement supports accurate velocity regulation with legacy Indramat analog servo amplifiers.
