Abstract

PURPOSE:To reduce the number of assembling processes drastically and to improve the density of magnetic flux on the surface of magnet remarkably by using anisotropic compound magnets. CONSTITUTION:Fan-shaped anisotropic compound magnets 3 are held by the holder 2 fixed to the shaft 1 to make up the roll-shaped magnet. The holder 2 is obtained by molding an isotropic compound magnet or synthetic resin, the radial pieces 6 and tip end stoppers 7 are provided to it. The anisotropic compound magnet 3 is made up by extrusion-molding a mixture of anisotropic-treated ferrite particles 8 and medium 9 such as rubber or synthetic resin while applying a magnetic field, a material in which the particles are arranged in the direction effective to the flow of magnetic flux to make themselves anisotropic is used, the section is made fan- shaped, the steps 11 are formed, and the magnet 3 is pressed into the space between the stoppers 7. In this way, the roll-shaped magnet is not damaged in the manufacturing process, no grinding is required, the number of assembling processes can be reduced, the density of magnetic flux on the surface of magnet can remarkably improved.
