This invent is a new construction of disc-type motors. It features: single stator, double rotors, double coil-slot in both faces of stator core, Ring-like coil, and ferrite stator core. In order to explain working principle conveniently, take an synchronous motor as an example. In fig.2, stator core (8) is assembled to frame (10) with supports(9), there are slots in both two faces of stator core(8), in which each plane faces a permanent magnetic steel(11) in rotor(6) and(12). The moving interval space is about 1mm. Ring-like coils(19) stride over stator core(8) and round in two opposed slots. The opposed permanent magnetic steel(11) in rotor(6) and (12) are same magnetic property. (in fig 2, at this moment, the above magnets are N poles and below are S poles). The bellow magnetic lines of flux flow from stator(8) to above magnetic steels in both two rotors, through rotor yokes (6) and (12) , magnetic lines of flux go to above two magnetic steels, at last return back to stator core. This process forms a ring of magnetic lines of flux. The electric current in above Ring-like coil is in clock-wise, and below is in counter-clock-wise, obviously the whole coils are receiving the same direction moment, and the motor begins to run.
