Product Description:

The MAC090B-0-JD-4HC/110-A-0/WI524LX is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Built as a drive component for analog servo loops, the motor converts velocity and position setpoints from an external controller into mechanical rotation for tasks such as indexing tables, pick-and-place arms, or light machining spindles. Its housing, terminal layout, and feedback options are tailored to integration in industrial enclosures that already provide the required power electronics and protective circuitry. This arrangement keeps the motor compact because sensing functions remain on the motor while the power stage stays in a separate control cabinet.

This model is supplied without a blocking brake, so mechanical holding force must be provided externally when the axis is de-energized. Thermal losses are removed by natural convection cooling, eliminating the need for forced airflow and allowing installation in sealed cabinets with modest ambient temperatures. Power conductors reach the stator windings through a connector on side A, an arrangement that keeps cabling on a common connection face. This layout can simplify cable routing when the motor face is positioned close to a machine frame or protective cover. Shaft alignment against the driven load is guided by a 110 mm centering diameter, which mates with precision pilot bores on gearboxes or mounting plates to minimize radial runout. The unit is classified as a motor for analog drives, indicating that its current control and velocity loops reside in the external amplifier rather than in onboard electronics.

Speed and position information are handled by a DC tachogenerator of standard tacho quality that produces 1.5 V per 1000 rpm for velocity feedback. Commutation and incremental motion data come from a tacho-feedback incremental or absolute encoder mounted in the rear housing, letting the external amplifier compare commanded motion with measured shaft response during closed-loop operation. For systems that only require quadrature signals, an incremental encoder with standard mounting can be selected, ensuring compatibility with most analog servo controllers without additional adapter plates or interface converters.
