Abstract: A generator of the present invention is formed of ring permanent magnet trains 2 and 2′ attached and fixed onto two orbits 1 and 1′ about a rotational axis 3, magnetic induction primary cores 4 and 4′ attached and fixed above outer peripheral surfaces of the ring permanent magnet trains 2 and 2′ at a predetermined distance from the outer peripheral surfaces, magnetic induction secondary cores 5 and 5′ attached and fixed onto the magnetic induction primary cores 4 and 4′ and each having two coupling, holes 6 and 6′ formed therein, tertiary cores 8 and 8′ inserted for coupling respectively into two coupling holes 6 and 6′ of each of the associated magnetic induction secondary cores 5 and 5′ opposite to each other, and responsive coils 7 and 7′.
