A stator for electrodynamic machines provides for more efficient design by reducing the total number of stator legs required for two-speed, two-phase motors and for generators producing electrical power at either of two frequencies while operating at a constant speed. This is accomplished by external switching, so that at one condition, all coils on all stator legs are energized in the normal symmetrical pattern, while at the other condition, all coils on all stator legs are energized in a non-symmetrical pattern.
