Product Description:

The MAC090A-0-ZD-4-C/110-A-1/WI520LX/S001 belongs to the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. It is a motor for analog drives that provides closed-loop rotary motion to automated equipment such as gantry axes, feeders, or web-handling stations. Within an automation cell, the unit converts current from the drive into torque while its feedback devices report position and velocity back to the controller, enabling precise, coordinated movement. This arrangement suits applications that need stable speed control and repeatable starts and stops under changing load conditions.

The motor’s centering diameter is 110 mm, giving a reference surface that aligns the housing concentrically with the mounting flange. Heat is removed by natural convection, so installation must allow unobstructed airflow around the frame. The motor has a nominal speed of 1500 rpm, which is its rated operating point for continuous duty. The power leads exit through a connector on side A, which fixes cable routing toward the drive cabinet and simplifies service access. The ZD winding code identifies the resistance and inductance values matched to the drive’s current range. A blocking brake is supplied as standard, and it locks the shaft mechanically when drive power is removed to help prevent back-driving on vertical or indexed axes.

For speed feedback, a tachogenerator delivers 3 V/1000 rpm, supplying the drive with an analog signal proportional to rotor velocity. Position feedback is provided through an incremental encoder mounted in the standard interface, and the design also accepts absolute encoder cartridges when higher resolution or multi-turn referencing is needed. The encoder supports more accurate position tracking than the tachogenerator alone during indexing and controlled stopping. This combination lets the controller use both velocity feedback and position feedback during operation.
