Abstract

“lâminas e rotores laminados de camadas múltiplas” resumo um rotor laminado de camadas múltiplas pode ser montado sobre um eixo para rotação em relação a um estator de uma disposição de máquina eléctrica rotativa. o rotor tem uma pluralidade de lâminas, unidas entre si, e espaços vazios para receber magnetos. uma seção de rotor anular, que circunda uma abertura do eixo dentro da qual pode ser recebido o eixo, estende-se entre a abertura do eixo do rotor e uma superfície circunferencial do rotor radialmente externa. a seção anular mencionada inclui uma série ondulante de espaços vazios em grupos de vazios que se estendem a partir da superfície circunferencial do rotor radialmente externa para dentro na direção da abertura do eixo e, em seguida, de volta para a superfície circunferencial do rotor radialmente externa, bem como uma parte maciça radialmente interior, sem qualquer um dos espaços vazios. vazios distais nos grupos de vazios incluem curva, arqueada, ou estresse recurvado aliviar características de alívio de esforço que se estendem para dentro partir de localizações de canto radialmente mais internas do referido par de vazios distais. 1/1
