Аннотация: In order to account the magnetic permeability in a ferromagnetic medium for the secondary element of electromechanical power converter it is suggested to use an equivalent rotor model. It has the form of a symmetrical magnetic multi-port circuit with the number of poles equal to the number of rotor teeth. This model permits to estiПоказать полностьюmate approximately the influence of teeth on electromagnetic process in a rotor bar and electric parameters of a faulted cage which are related to a stator winding. An approximate analytical solution of the task for determining electric parameters of a deep-slot foulted rotor has been obtained. This solution takes account of surface effect in bars and magnetic permeability of rotor steel simultaneously.
