Abstract

"SISTEMA DE CORREçãO PARA O CASO DE PATINAçãO DA RODA". Um sistema de correção para o caso de patinação da roda para um veículo propelido por um motor elétrico de tração apresentando uma pluralidade de motores de tração elétricos DC, cada qual apresentando uma série de induzidos ligados e de enrolamentos de campo incorporando um dispositivo ligado em circuito com cada motor para reduzir a corrente no induzido do motor em resposta a um aumento na velocidade do motor causada pela patinação de uma roda. O dispositivo é disposto de modo a não dissipar energia durante as condições de não patinação da roda.
