Development of a stand construction concept for safe and efficient after-repair tests of induction motors up to 1 kV

The article describes the use of single-phase and three-phase induction motors, their main advantages and disadvantages are given. The aim of the study was to analyze the types and characteristics of repair of electric machines, to study the volumes and norms of testing induction motors, to review the software for the post-repair test of induction motors up to 1 kV, as well as to develop a concept for constructing a stand for automated post-repair testing of induction motor. The possibility of using the proposed stand, which will allow testing of induction motors in a wide range of sinusoidal load currents in all operating modes with simulated operating modes close to operational, is substantiated, which will make it possible to objectively assess the quality of repair of an electric machine, its energy performance compared to passport ones.
