<p>The invention relates to a permanent magnet motor and to an electric generator derived therefrom. According to the invention, the motor comprises a stator () having a non-magnetic stator support () with platelet-type parallelepipedal stator magnets () which are arranged in a transverse way, normal to the rotation plane, with the width in an angle of 30...60° in relation with the radial direction, with the polarization P parallel with the length or width, dyssimetrically screened by means of some ferromagnetic screens (), and a rotor () which, on a shaft () fixed in two bearings (), has a non-magnetic rotor support () with polarized rotor magnets () which are arranged in relation with the radial direction in the same way as the stator magnets and dyssimetrically screened by means of some ferromagnetic screens (), the stator magnets () and the rotor magnets () being repulsively placed and the thickness of the ferromagnetic screens () being selected in a range at the limit of suppression of the repulsion between these magnets reaching the aligned position without introducing braking forces by attraction of screen-opposite magnet type, they being so arranged as to permit mutual approach in the magnets rotation sense. In another embodiment, the dyssimetrically screened stator magnets () and the rotor magnets () are radially arranged under an angle of 15...45° as against the rotation plane, with anti-parallel polarizations, while in the magneto-electric generator embodiment, the screens () of the stator magnets () are profiled with their ends adjacent to the ends of the stator magnets () and with their medial part slightly spaced apart therefrom, so as to form a ferrous core for some electric current-inducing solenoids ().</p> |
