Abstract

SE PRESENTA UN DISPOSITIVO ELECTROMOTRIZ (10) QUE UTILIZA PILAS DE MATERIAL MAGNETICO COMO BARRAS ESTATICAS (40). LOS CONDUCTORES ELECTRICOS (40) SE ENROLLAN ALREDEDOR DE LAS BARRAS ESTATICAS (40) PARA CREAR UN INDUCTOR ESTATICO (36). LAS BARRAS ESTATICAS (40) SE CONFIGURAN PARA PROTEGER EL BOBINADO DE LOS CONDUCTORES ELECTRICOS (38) DE FUERZAS ELECTROMAGNETICAS Y PARA PROPORCIONAR UNA PRIMERA RUTA DE RETORNO PARA EL FLUIDO MAGNETICO CREADO POR IMANES (34) FIJADOS A UN ROTOR (32) PARA MOVIMIENTO RESPECTO AL INDUCTOR ESTATICO (36).
