Abstract

Patente de Invenção: <B>"MOTOR ELéTRICO"<D> Em motores elétricos é conhecido dispor ao menos dois segmentos de ímã permanente dispostos em torno de um eixo longitudinal de motor; os quais, cada, têm duas faces terminais transcorrendo na direção do eixo longitudinal de motor e são envoltos por dois segmentos de anel de fecho traseiro autónomos, os quais apresentam entre si uma fenda paralela em relação a um plano de simetria transcorrendo através do eixo longitudinal de motor e do centro dos segmentos de ímã permanente, a fim de reduzir o campo transversal do induzido. No motor elétrico, deve ser atingida, além da redução do campo transversal do induzido, adicionalmente, uma redução de peso do motor elétrico. Para isto, o fecho traseiro (3), executado inteiriço, condutor de magnetismo, é provido, em uma primeira região (13) próxima às faces terminais (14) dos segmentos de ímã permanente (4), com uma maior seção transversal do que em uma segunda região (15) próxima ao plano de simetria (16) transcorrendo através do centro dos segmentos de ímã permanente (4). A configuração apropria-se especialmente para pequenos motores elétricos, em particular motores elétricos de corrente contínua, excitados por ímã permanente.
