The parameters of the equivalent Г-circuit, which is proposed for this improvement method, may be derived by data from the no-load test and locked-rotor test at reduced frequency, but direct calculations, i.e. simpler than parameters of the conventional T - circuit. And as for the simpler Г-circuit, the operating characteristics (losses, output power, efficiency and power factor) are calculated with no loss of accuracy. The accuracy of the proposed procedure was verified on the basis of results of comparative calculations for motor given in the literature.
