Abstract

"DISPOSITIVO PARA GERAR ELETRICIDADE, PROCESSO DECONDICIONAR A SAìDA ELéTRICA DE UM GERADOR DEELETRICIDADE E MONTAGEM PARA CONTROLAR AVELOCIDADE DE ROTAçãO". um dispositivo tal como um motorelétrico, um gerador elétrico, ou um motor elétrico regenerativo queinclui uma disposição de rotor e uma disposição de estator. Adisposição de estator apresenta um compartimento de eletroímãsdielétrico e pelo menos um conjunto de eletroímãs energizávelincluindo um núcleo magnético de metal amorfo global. O núcleomagnético de metal amorfo global é constituído de uma pluralidadede peças de núcleo de metal amorfo formadas individualmente. Ocompartimento de eletroímãs dielétrico apresenta aberturas depeça de núcleo formadas no compartimento de eletroímãs parasustentação das peças de núcleo de metal amorfo formadasindividualmente em posições adjacentes entre si de modo aformarem o núcleo magnético de metal amorfo global. O dispositivoinclui ainda uma disposição de controle que é capaz de controlarde maneira variável a ativação e a desativação do eletroímãutilizando-se qualquer combinação de uma pluralidade deparâmetros de ativação e desativação de forma a se controlar avelocidade, eficiência, torque e potência do dispositivo.
