Laboratory stand for researching the modes of operation of the frequency converter of a three-phase asynchronous motor with a short-circuited rotor

Abstract

A laboratory stand was developed for researching the modes of operation of a frequency converter for controlling a three-phase asynchronous motor with a short-circuited rotor with a voltage of 380-400 V. The design of the laboratory stand and its electrical circuit are described. Methodical instructions for carrying out laboratory work on the study of operating modes of the frequency converter have been developed. The composition and structure of methodical instructions are given. In the electronic version of the developed methodological instructions, a hyperlink to the technical documentation of the investigated frequency converter on the Internet is used. To demonstrate the capabilities of the laboratory stand, separate results of research into the modes of operation of the frequency converter are presented.
