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