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."ELECTRIC MOTOR ROTOR", including: a core (10) and a cover (20) molded in one piece around the core (10) and incorporating magnet elements, and comprising: a plurality of radial projections (30) provided in at least one of the cover (10) and core (20) parts, and extended towards the other part; a plurality of radial receiver recesses (40) provided on the other of said parts, radially encased and retaining respective radial projections (30), in order to prevent the occurrence of relative radial displacements between the cover (20) and the rotor core (10) , each radial projection (30) and receiving recess (40) occupying at least part of the longitudinal extension of the respective part where they are provided and being circumferentially distributed around the core (10), in order to compensate the action of the centrifugal force acting on the cover (20) during operation of the rotor.
