Abstract

"MOTOR ELéTRICO GIRATóRIO TENDO PELO MENOS DUAS FOLGAS DE AR AXIALMENTE SEPARANDO SEGMENTOS DE ESTATOR E ROTOR". A presente invenção refere-se a um motor que tem um rotor e um estator. O estator é composto de uma pluralidade de segmentos de núcleos eletromagnéticos separados dispostos co-axialmente em torno de um eixo de rotação. Os segmentos de núcleo são afixados sem contato ferromagnético uns com os outros, em uma estrutura de suporte não ferromagnética. O rotor é configurado em um anel que circunda pelo menos parcialmente o estator anular para definir duas folgas axiais paralelas entre o rotor e o estator, respectivamente em lados axiais opostos do estator. ímãs permanentes são distribuídos em cada lado do anel de rotor que faceia uma folga. De preferência, cada segmento de núcleo eletromagnético de estator tem um par de pólos alinhados em uma direção, geralmente paralela ao eixo de rotação com faces de pólos, geralmente perpendiculares ao eixo de rotação. Um enrolamento é formado em uma porção de núcleo que liga os pólos para produzir quando energizado, pólos magnéticos de polaridade opostas nas faces dos pólos.
