Abstract

Patente de Invenção: <B>"SISTEMA DE VENTILAçãO PARA O ENROLAMENTO DE EXCITAçãO DE MáQUINAS POLARES DE PERNAS DE GRANDE PORTE"<D>. Para melhor refrigeração dos enrolamentos de excitação de uma máquina polar de pernas de grande porte, particularmente para energia hidráulica, estão inseridos nas camadas de enrolamento (4) dos enrolamentos de excitação (21) caminhos de corrente (2), que adicionalmente aos vãos polares (1), levam meio de refrigeração radialmente para fora.
