【Abstract】 This paper presents analytical method for performance characteristics of a three phase induction motor when fed from a single phase supply.Starting as well as running of such motor are achieved by connecting a capacitor across two of stator phase in a way to act as a phase converter.Symmetrical components concept was employed in the analysis.Formulas are derived for calculating running and starting capacitance.The calculating results are validated by the actual testing values.更多还原
