PURPOSE:To improve the output efficiency by using permanent magnets double as a stator, and using a rotor as squirrel cage to form magnetic fields at the inside and outside. CONSTITUTION:Permanent magnets 1a-4b are disposed at the same angle interval on the same radial lines 1-4 of two imaginary concentric circles P, Q of different diameters. The magnets 1a-4b on the same radial line are directed at N- and S-poles toward the same central point, and disposed so that the permanent magnets on the adjacent radial lines are reverse in the directions of the N- and S-poles. Further, a rotational shaft 20 is provided on the same axis as a central point O, a frame 10 having squirrel cages 11-14 rotating between inner and outer permanent magnets is provided, and electromagnets 11c-14c are mounted on the cages 11-14. Thus, when the electromagnets 11c-14c pass between a set of inner and outer permanent magnets, the polarity become reverse to act a repelling force between both and an attracting force to the adjacent permanent magnet to rotate. |
