This is the image i saw, referring to the explanation of the 3Phase Synchronous motors. The doc says it is an empty stator containing just 3 coils, each 120 Degrees apart around the surface of the machine. But I see 6, like abc,a'b'c'. What are these a'b'c' coils? When it is referred to 3 coils does it always mean always 6 terminals. It can be different in different docs? Please advise.
