A motive power generating apparatus utilizing magnetic flux from permanent magnets providing higher efficiency and torque is disclosed. An apparatus according to one embodiment of the present invention comprises a pair of disc-shaped rotors 10 and 20, a pair of ring-shaped stators 30 and 40, a rotational shaft 50, a permanent magnet 60, and a current controller 80. Each rotor 10, 20 is a disc-shaped member formed of magnetic material. Each stator 30, 40 further includes twelve electromagnets 32, 42 provided along the outer periphery of each disc-shaped rotor 10, 20 at intervals of thirty degrees. Each electromagnet 32, 42 has an armature 32a, 42a and a winding 32b, 42b. Each rotor 10, 20 contains six sets of protruding poles 10a, 20a disposed around the outer periphery thereof at intervals of sixty degrees. Each rotor 10, 20 is magnetized in opposite polarities by the permanent magnet 60 disposed therebetween. Since every other electromagnet 32, 42 corresponds to each of the protruding poles 10a, 20a of the rotor 10, 20, the adjacent electromagnets 32, 42 are energized in opposite polarities while the polarities are reversed by every thirty degree rotation of the rotors 10, 20 to continuously attract the adjacent incoming protruding poles 10a, 20a magnetically.
