Abstract
The invention relates to a rotor for an inverted (in-out) electric machine of the type having a stationary shaft, which allows the manufacturing costs to be lowered and the rotor efficiency improved, comprising a toroidal element 15 and two covers 19. The toroidal element comprises core laminations and shorting rings 16 cast thereon, as well as surfaces 28 intended to adhere against the covers. The covers comprise each a hub 23 wherewith a bearing 24 is made rigid which rotates therewith, and surfaces 31 mating with the surfaces of the toroidal element. The invention further concerns a method of manufacturing said rotor, and an inverted electric rotary machine incorporating it.
