This work presents a method of general two-phase harmonic symmetrical components, for the analysis and calculation of single-phase induction motor characteristics with shaded poles and two short circuited auxiliary phases. The method is based on rotating field theory applying the harmonic symmetrical current components of direct and inverse order. Thus, it is possible to make a motor characteristic analysis by taking into consideration the action of all significant space harmonics of the magnetomotive forces (MMF) to the rotor cage winding. The advantage of the presented method in regard to other methods is that the shaded pole motor calculation (by enlarging with the higher space harmonics MMF) is united in such a way that it is possible to apply the same calculation program to all structural types with either one or both of the auxiliary phases short-circuited
