Abstract

"ROTOR PARA MOTOR ELéTRICO". Rotor para motores elétricos, no qual as lâminas de dois tipos e dispostas alternadamente são fabricadas de uma maneira que um primeiro tipo é provido de uma pluralidade de protuberâncias formadas por respectivas ling³etas protuberantes, uma pluralidade de perfurações sendo perfuradas na lâmina próximo à borda da respectiva ling³eta com o mesmo padrão de orientação destas, de modo a se criar uma seq³ência alternada de ling³etas e respectivas perfurações, em que uma respectiva cavidade é provida na respectiva lâmina, em correspondência às lâminas do citado primeiro tipo, ao passo que o segundo tipo de lâminas é provido de uma pluralidade de diferentes ling³etas adaptadas para se engatarem em cavidades formadas pela associação dos citados rebaixos que correspondem às citadas primeiras ling³etas com as respectivas perfurações, em que as tiras do segundo tipo são produzidas sem a remoção de material.
