The invention relates to an intelligent electric actuator device based on a variable frequency control technology. The intelligent electric actuator device mainly comprises a switched reluctance motor, an actuator controller, an actuator position sensor, a reduction gearbox, an electric junction box, a hand wheel, a worm and an output tension arm; the switched reluctance motor is a switched reluctance motor with variable frequency control, is taken as a position control motor element of the electric actuator and realizes the accurate fine adjustment and the positioning of the electric actuator; and the controller is an integral control structure of the electric actuator formed by using an integrated chip DSP as the inner core, an SPM module as the power conversion unit and a PROFIBUS bus as the communication medium. The invention has the advantages that the intelligent electric actuator device has flexible and convenient installation, simple mechanical structure and stable and reliable performance, and can be widely used for the automatic adjustment of the production process of the industrial departments such as metallurgy, oil, power stations, chemical engineering, light textile,and the like.
