Product Description:

The MAC025B-0-ZS-4-E/040-A-0/WI668LV is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It serves as a compact rotary actuator that converts command currents from drive electronics into precise shaft rotation for pick-and-place heads, conveyor indexing points, and light machine-tool spindles. Integrated speed and position sensors transmit real-time data to the controller, so the axis can hold programmed trajectories even when loads vary. Its small frame and passive cooling allow placement in crowded cabinets or on moving carriages where forced airflow is not practical.

The mechanical package uses frame size B and length code 025, which helps limit overall stack depth for machinery with tight axial clearances. Heat is removed through natural convection, so the housing releases thermal energy to the surrounding air without fans and reduces maintenance points. Power conductors terminate through a power connector on side A, so motor and feedback harnesses can exit the same machine wall and shorten cable runs. The rotor is held only by electromagnetic torque because the unit is supplied without a blocking brake, so machines that need static holding must add an external clamp or rely on drive current.

For interface selection, the motor is classified as a motor for analog drives, meaning its windings are intended for analog drive systems that generate sinusoidal phase currents. Motion verification is handled by the factory-installed feedback set listed as tacho feedback with an incremental or absolute encoder, providing either velocity feedback or absolute position data. The primary sensor is an incremental encoder with standard mounting, so replacement heads can fit the pilot diameter without shims. This configuration keeps the motor compatible with legacy analog controllers and also allows support through modern interface cards.
