Analysis of unsymmetrical machines

By making use of suitably chosen components of current and voltage, the method of symmetrical components, which is so useful in the analysis of symmetrically wound polyphase a-c machines, can be extended readily to the analysis of unsymmetrical 2 phase induction machines, such as the capacitor or split phase motor in which the windings are not in space quadrature. Such extensions to this method, illustrated by a typical numerical example, are presented in this paper.
