Symmetrical components as applied to the single-phase induction motor

THIS PAPER is intended to show in detail the application of the method of symmetrical components to the solution of single-phase-induction-motor performance characteristics. By the use of this method single-phase-motor theory follows very closely the simpler case of the balanced polyphase-motor theory. The author of this paper is of the opinion that a clearer concept of the physical theory can be obtained as contrasted to other methods — either from the revolving-field or the cross-field concepts.
