One of the possible fields of application of the impedance method based on the use of impedance and its components as an informative parameter is considered. This area of work is the study and diagnosis of asynchronous motors in dynamic mode. The paper presents both a T – shaped scheme of replacement of an asynchronous motor and one of its possible mathematical models, on the basis of which conclusions were made about the feasibility of applying the impedance method for the study and diagnosis of asynchronous motors and the need to develop hardware for this method. In this regard, the main part of the work is devoted to the consideration of measuring transducers necessary for both the technical implementation of the method as a whole, and the instrument support of the method. The option to build transmitters that use the basis four-armmeasuring bridge circuit known as a Wheatstone bridge. The first сonverter is easier to implement because it is implemented on the basis of the Whitstonbridge with one feedback, but is characterized by less functionality. The second converter is implemented more difficult, as it is also implemented on the basis of the Whitstonbridge, but with two feedbacks. However, this version of the converter has more functionality.
