Product Description:

The MAC025C-0-QS-4-E/040-B-0/WI670LV/S001 is an AC servo motor in the MAC AC Servo Motors series manufactured by Bosch Rexroth Indramat. Designed as a compact electromechanical drive element, it converts drive commands from analog velocity or current loops into controlled shaft motion for positioning, conveying, indexing, and tooling stations within automated equipment. By integrating stator windings, permanent-magnet excitation, and encoder feedback, the unit delivers closed-loop torque and speed regulation that is essential for repeatable machine cycles and synchronized multi-axis operation. In automated machinery, this allows the connected drive electronics to react quickly to load changes and keep commanded motion more consistent during normal production.

The motor has a size of 025 and a frame length of C, which set the mounting footprint and active stack length for compact axes. Power conductors enter through a connector on side B, which simplifies cable routing in cabinets where the rear of the motor is difficult to reach after installation. Heat generated in the windings is removed solely by natural convection, so no external blower or liquid circuit is required. This cooling method reduces supporting hardware around the motor and supports use in enclosed machine spaces where available airflow is limited.

For signal processing, the motor is intended for analog drives, and its shaft position is monitored by an incremental encoder with standard mounting that sends pulse feedback to the drive controller. This feedback allows the controller to compare commanded and actual motion so speed changes and position updates can be tracked during routine axis movement. Because the mechanical design is without a blocking brake, holding torque must be supplied by the drive or by an external clamp when the application requires static positioning during power-off conditions. That arrangement is common on axes that operate under active control and do not need an integrated parking brake.
