Abstract

COMUTADOR E MéTODO DE COMUTAçãO DE CORRENTE EM UMA MáQUINA ELéTRICA DE ROTAçãO Um comutador para rotação com ou pelo eixo de uma máquina elétrica tem primeiro e segundo segmentos de comutador eletricamente condutor fornecido em uma base para engajamento elétrico com escovas conectadas a enrolamentos. Isolada e distribuída entre os segmentos do comutador estão o primeiro e o segundo segmento de roda livre. Um primeiro diodo está conectado entre o primeiro segmento comutador e o primeiro segmento de roda livre. Um segundo diodo está conectado entre o segundo comutador e o segundo segmento de roda livre. Os diodos permitem que a corrente flua em apenas uma direção entre o comutador e os segmentos de roda livre para ajudar a suprimir o centelhamento da comutação.
