A stepper motor drive system consists of a stepper motor and the matching stepper drive. The 3 ph stepper motors from Schneider Electric are extremely robust, maintenance free motors. They carry out precise step by step movements that are controlled by a stepper motor drive. Maximum power can only be obtained if motor and electronics are perfectly tuned to each other. The 3 ph stepper motors can be operated at very high resolutions depending on the stepper motor drive. Options such as rotation monitoring and holding brake as well as robust, planetary gears with little backlash extend the application possibilities.
