Abstract
"ROTOR PARA MOTOR ELéTRICO", incluindo: um núcleo (10) e uma capa (20) moldada em peça única em torno do núcleo (10) e incorporado elementos de magneto, e compreendendo: uma pluralidade de projeções radiais (30) providas em pelo menos uma das partes de capa (10) e núcleo (20), e estendida em direção à outra parte; uma pluralidade de recessos receptores radiais (40) providos na outra de ditas partes, radialmente encaixnado e retendo respectivas projeções radiais (30), de modo a impedir ocorrência de deslocamento radiais relativos entre a capa (20) e o núcleo (10) do rotor, cada projeção radial (30) e recesso receptor (40) ocupando pelo menos parte da extensão longitudinal da respectiva parte onde são providos e sendo circunferencialmente distribuídos em torno do núcleo (10), de modo a compensarem a ação da força centrífuga atuante sobre a capa (20) durante operação do rotor.
