In order to develop viable methods for engineering calculations, the author applies field equations. The resulting, new methods consist of traditional calculation elements represented in a refined form (circuit-loops, parameters, equivalent circuits and voltage equations). These calculation methods should be effective both for researchers and engineering practitioners, especially, in relation to the modern electric machines, such as powerful turbine generators, large high-speed synchronous motors, etc. Provides conditions for the generalization of the field research results; Expands capabilities of engineering calculation methods; Improves upon the theory of engineering calculations, under the conditions of the Maxwell’s equations.Power electronicsElectric machineryElectronic circuitsPower ElectronicsElectrical MachinesElectronic Circuits and SystemsPower electronics.Electric machinery.Electronic circuits.Power Electronics.Electrical Machines.Electronic Circuits and Systems.621.3136621.3136Asanbayev Valentin720913MiAaPQMiAaPQMiAaPQ9910583507203321Asynchronous Machines2899607UNINA
