ABSTRACT:
A motive power generating apparatus using magnetic flux from permanent magnets providing higher efficiency and torque is disclosed. An apparatus of one embodiment according to the present invention comprises a ring-shaped stator (10) formed of magnetic material, a rotor (20) including at least one permanent magnet (22a), and a current control circuit (40). The stator (10) further includes twelve stator poles (12) provided along the inner periphery thereof at intervals of fifteen degrees. Each of the stator poles (12) has a pole piece (12a) and a winding (14). The rotor (20) contains twelve sets of rotor poles (22) disposed around the outer periphery thereof corresponding to the above stator poles (12). Each of the rotor poles (22) has a permanent magnet (22a) and a pole piece (22b) arranged at the outer end portion of the same. An extending portion (22b1) is provided with each of the pole pieces (22b) at one tip end in rotational direction thereof. Each of the rotor poles (22) is attracted by an excited stator pole (12) in the opposite polarity to that of the corresponding rotor pole (22) positioned forward to cause a clockwise rotation to the rotor (20) since a magnetic flux is converged to the extending portion (22b1). Current direction in each of the windings (14) is alternated every fifteen degrees of rotation to change the polarity of each of the stator poles (12) so as to continue rotation of the rotor (20).
