Abstract

Patente de Invenção:<B> "MOTOR DE INDUçãO DE FASE úNICA COM COMUTAçãO BIDIRECIONAL E PROTEçãO DE SOBRECARGA''<D>. A presente invenção refere-se a um sistema de motor com controle bidirecional e proteção de sobrecarga. O sistema compreende um enrolamento principal, um enrolamento auxiliar, um capacitor, um comutador e um protetor de sobrecorrente. O enrolamento auxiliar é conectado em paralelo ao enrolamento principal. O capacitor é acoplado aos enrolamentos principal e auxiliar. O comutador é conectado em paralelo com o capacitor para controlar a direção de rotação do motor. O protetor é acoplado aos enrolamentos principal e auxiliar. O protetor inclui um aquecedor de enrolamento principal, conectado em série com o enrolamento principal, um aquecedor de enrolamento auxiliar, conectado em série com o enrolamento auxiliar, e um único contactor em série com os enrolamentos. O contador é controlado pelos aquecedores e interromperá o fluxo de corrente através dos enrolamentos, quando ocorrer uma condição de sobrecorrente.
