description: The subject of research of this graduate qualification work of a bachelor is the rotational speed sensors of asynchronous motors. The purpose of the work is to develop an automated device for testing speed sensors of asynchronous motors. Results of work. In the course of the work, a review was made of the frequency converter system - an asynchronous motor with negative speed feedback, the principle of operation of the Hall effect speed sensor was considered, the types of speed sensors used on the rolling stock, oscillograms of the main malfunctions of such sensors on the rolling stock were presented. A functional diagram of the verification device has been developed, which fully reveals the approaches to the design of the circuit, the choice of a microcontroller, a display module and other electronic components of the device board has been made. An electrical circuit diagram has been developed based on the selected components. Scope - organizations operating asynchronous electric motors with speed sensors on the Hall effect. Conclusions on the work. An automated device for checking the speed sensors of asynchronous motors has been developed, which makes it possible to check their functioning in an automated mode.
