Abstract

Method of manufacturing stators and rotors for use in electrical appliances comprising at least two permanent magnets arranged in a circle shape and diametrically opposite each other while the direction of magnetization is radial characterized by the fact that the magnets are segmental and They consist of a material known from patents Nos. 198.834205.897206.853 and 208.433 and that since they contract to different degrees during fusion have different internal and external radii of curvature from each other they are placed against a template comprising three circular cylindrical parts located diametrically opposite each other, the template between these parts comprises other parts between which the diametrical separation is different from that between the parts mentioned in the first term, after which the segments are joined to form a set by means of high-permeability ferro-magnetic material .
