Abstract

Improvements in the manufacture of rotors for magneto-alternators characterized in that in each plate are cut simultaneously all the poles that form a single crown with sections of smaller width corresponding to the areas of unión between poles. These sections of smaller width can be in the periphery of the inner hole of the polar crown or in that of the outer hole, according to whether the magnets are disposed towards the outside or toward the inside. In the first case in which the magnets are disposed towards the outer surface, after the crown has been injected when the pole pieces and the magnets will continue to retain the mounting position, the turning is made through the face of the inner hole to a diameter such that the part of smaller width is made disappear, with what the polar pieces are independent having been taken advantage of for the assembly of the fact that initially they formed a single piece. In the case that the magnets present their faces directed towards the interior, the links of smaller width of the pole pieces are on the outside, with which the turning of the assembly once injected is effected externally until the disappearance of the bridge pieces. Of smaller width that initially link the polar pieces. This solution of cutting the poles simultaneously from a plate is applicable to any number of poles.
