Product Description:

The MAC090A-0-ZD-4-C/110B-1/WI594LV is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Intended for use with analog velocity and current controllers, the unit supplies programmable torque and speed to positioning tables, feeders, and converting machinery. By coupling a permanent-magnet rotor with integrated feedback, it serves as the electromechanical interface that links the drive amplifier to the mechanical load in industrial automation cells.

It mounts to the machine frame through a centering pilot of 110 mm, which aligns the stator housing concentrically with gearboxes or flanges and helps keep shaft runout low. Heat generated in the stator windings is removed by natural convection, so no external blower or liquid circuit is required. The winding code ZD indicates the copper fill and magnetic configuration associated with the motor’s torque constants and impedance values. At its nominal operating point, the rotor turns at 1500 rpm, allowing direct coupling to standard 1:1 mechanical transmissions without overspeeding. Speed is monitored by a tacho generator that delivers 3 V/1000 rpm, giving the drive controller an analog signal proportional to shaft velocity for closed-loop regulation.

The motor is supplied with tacho feedback and an incremental or absolute encoder, supporting analog velocity feedback and high-resolution digital position data through the same mechanical interface. This feedback arrangement allows the connected controller to monitor shaft motion and correct deviations caused by changing loads during operation. Classified as a motor for analog drives, the unit is designed to operate with voltage-controlled amplifiers rather than fieldbus-based servo modules. The tacho assembly has a Standard grade, indicating ripple and linearity tolerances suitable for general-purpose motion tasks. Its combination of velocity and position feedback supports controlled acceleration, steady running, and accurate stopping in automated equipment.
