Abstract
PURPOSE: To change the magnetic orientation and heighten the surface magnetic flux density, by embedding magnetically anisotropic pieces in laminated magnet sheets of magnetic anisotropy.
CONSTITUTION: A mixture containing scale-shaped ferrite grains treated to magnetic anisotropy and rubber or synthetic resin is rolled, thereby producing the magnet sheet 4 having ferromagnetism in the direction of the thickness. The magnet sheet 4 is wound by a predetermined number of turns on a round shaft 5. The wedge-like magnetically anisotropic pieces 6 harder than the magnet sheet 4 are embedded in the wound magnet sheet correspondingly to the number of magnetic poles. Thereby, the magnetic orientation of the intermediate parts between the magnetic poles is sequentially changed by an angle near 90°. Thereafter, magnetizing yokes 7 are set on the magnetic pole parts (h) to magnetize the sheet. The laminated piece may be flat.
