Abstract: A sort of electromagnetic motor having: the first rotor and the second rotor with independent and coaxial rotation around a rotation axis, including respectively the first and the second permanent magnet, having the first and the second permanent magnet respectively the first and the second plurality of magnetic twin-poles, being the first and the second plurality of magnetic twin-poles positioned regularly in a circular form around the rotor, in parallel with said rotor in the first direction and counter to the second direction, having both an axial geometric axis, having the geometric axis of the 2 adjacent poles of the first magnet forming as the first angle of a1=360/N1 as the first angle, where N1 is the number of the twin-pole of the first magnet and the second angle of a2=360/N2 formed in the center of the geometric axis in the twin-pole of the second magnet, where N2 equals the number of the twin-pole of the second magnet; the first stator, including the first and second stator pole divided by the first stator opening and the first and the second plurality of teeth being the first and the second plurality of teeth extended from the stator opening edge toward the rotor in a radial manner and facing the first magnet, with an radial axis and two teeh bellies adjacent to the axis of the two teeth of the first plurality of teeth and the axis of the second plurality of teeth adjacent to it, forming the third angle of B1=2q1 in the center, being the one of the first and the second plurality of teeth corresponding to the other^s teeth of the first and the second plurality of teeth in the counter triangular geometrical shiaft equalling +2a1/3 shift angle; the second stator including the third and fourth stator pole divided by the second stator opening and the third and the fourth plurality of teeth being the third and the fourth plurality of teeth extended from the second stator opening edge toward the rotor in a radial manner and facing the second magnet, with an radial axis and two teeh bellies adjacent to the axis of the two teeth of the fourth plurality of teeth and the axis of the second plurality of teeth adjacent to it, forming the fourth angle of B1=2a1 in the center, being the one of the third and fourth plurality of teeth corresponding to the other^s teeth of the first and the fourth plurality of teeth in the counter triangular geometrical shiaft equalling +2a2/3 shift angle; the third stator, including the fifth stator pole between the magnets having the magnet further between the fifth stator pole and the first and the second stator poles and otherwise between the fifth stator pole and the third and the fourth stator poles; the first coil, including a core with the first and the second lead being the core coupled magnetically to the first and the fifth stator pole; the second coil, including a core with the first and the second lead being the core coupled magnetically to the third and the fifth stator pole; the third coil, including a core with the magnet having the first lead being coupled to first and the second stator pole and the second lead coupled to the fifth stator pole.
