CA 2655210

A rotor assembly for an electric motor is constructed by adding bars made out of a conducting material such as copper, to spaces between the teeth of a stack of discs, inserting bars referred to as "slugs", also made out of a conducting material such as copper, in the spaces between the bars on either side of the stack of discs, radially compressing the bars and discs, one or both of which are plated or otherwise coated with a braising material, and then heating the rotor to allow the bars to be braised to the slugs.

La présente invention concerne un ensemble rotor pour un moteur électrique construit par ajout de barres composées d'un matériau conducteur tel que le cuivre, à des espaces entre les dents d'une pile de disques, par insertion de barres désignées en tant que manchons, également composées d'un matériau conducteur tel que le cuivre, à des espaces entre les barres de chaque côté de la pile de disques, par compression radiale des barres et des disques, les barres et/ou les disques étant plaqués ou autrement revêtus d'un matériau de brasage, puis par chauffage du rotor pour permettre le brasage des barres aux manchons.
