Product Description:

The MAC090A-0-RD-4-C/110-A-0/WI522LV is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for use with analog drive amplifiers, it supplies regulated torque and speed for automated axes such as indexing tables, conveyors, and pick-and-place arms. By translating current-loop commands directly into rotary motion, the motor provides the electromechanical interface between the control system and the driven load in industrial automation. In automated equipment, this supports smooth starts, speed changes, and controlled stopping under drive supervision.

The stator housing includes a centering flange machined to 110 mm, keeping the shaft aligned with gearboxes or mounting plates. Heat from the windings leaves the frame by natural convection, so no blower or coolant loop is required and ambient airflow must stay unobstructed. Power conductors exit through a connector on side A, which routes the cable toward the drive cabinet and leaves the feedback end clear. The motor has no blocking brake, so external restraints must secure vertical loads when power is removed. For velocity feedback, the motor is wired for tachofeedback and incremental or absolute encoder operation. Its winding constants match a motor for analog drives governed by current-loop amplifiers.

Complementing the dual-feedback option, the motor carries standard tacho quality components that provide consistent voltage per speed unit for legacy regulators. When pulse-train feedback is preferred, the internal incremental encoder with standard mounting supplies evenly spaced channels and uses a common mounting arrangement within this flange size. This arrangement supports applications that use analog speed regulation as well as systems that rely on pulse-based position feedback. Because the feedback devices are integrated into the motor, the axis can be connected without separate external sensing hardware. It also helps older control platforms remain compatible while still allowing encoder-based feedback.
