Abstract

The principle of operation of a three-phase asynchronous motor with a short-circuited rotor is considered and the theoretical bases of the transformation of electric energy in electromechanical converters of an electromagnetic type are analyzed. In order to construct a mathematical model of an asynchronous motor with a short-circuited rotor for obtaining characteristics to describe the dynamics of electrical asynchronous machines, the physical configuration, which is typical for most electric machines, is proposed. An approach to choose a coordinate system has been developed in which the system of equations describing the operation of the asynchronous motor would be described. Requirements for the magnetic system and phase zones of the model have been developed, which in the future can be used to determine the parameters of the mathematical model of the asynchronous motor, which cannot be determined by the catalog and reference data. In developing the requirements for the magnetic system and phase zones, it is taken into account that windings of the asynchronous motor can be both symmetric and asymmetric. The developed requirements can be used to develop a method for analytical determining the parameters of an asynchronous motor, which will allow the specified parameters to be determined as a function of the geometric dimensions of the windings of the engine.
