Abstract

"CIRCUITO MAGNéTICO, ESTATOR E ROTOR DE UM MOTOR ELéTRICO, APARELHO E MOTOR ELéTRICO". Lâminas metálicas para circuitos magnéticos. Algumas das modalidades ilustrativas podem ser representadas por um circuito magnético compreendendo um trajeto de fluxo magnético de baixa relutância compreendendo uma pluralidade de lâminas metálicas enfeixadas (cada lâmina tendo uma borda), e um entreferro em relação operacional com pelo menos uma parte das bordas das lâminas metálicas enfeixadas (em que o fluxo magnético flui pelo menos parcialmente através das lâminas metálicas enfeixadas e do entreferro). Bordas adjacentes das lâminas metálicas enfeixadas são intencionalmente deslocadas por uma extensão maior que a tolerância de fabricação da posição de borda para as lâminas metálicas enfeixadas para aperfeiçoar a perda de corrente parasita que ocorre como resultado do contato de lâmina com lâmina nas bordas.
