Abstract

ESTRUTURA DE ROTOR - ESTATOR PARA MáQUINAS ELETRODINáMICAS. A presente invenção refere-se a uma estrutura de rotor - estator (250, 200) para um maquinário eletrodinâmico para, entre outras coisas, minimizar os comprimentos de percurso de fluxo magnético e eliminar o contra-ferro para aumentar o torque e/ou a eficiência por tamanho unitário (ou peso unitário) e para reduzir os custos de fabricação. Em uma modalidade, uma estrutura de rotor - estator (250, 200) exemplar pode compreender um eixo (225, 222) que define um eixo geométrico de rotação, e um rotor sobre o qual pelo menos dois ímãs (226a, 226b; 220a, 220b), estão montados sobre o eixo (225, 222). Os dois ímãs podem ser ímãs cilíndricos (226a, 226b) ou cónicos (220a, 220b) que têm superfícies magnéticas que confrontam os entreferros. Em algumas modalidades, membros de pólo de campo substancialmente retos podem estar dispostos coaxialmente e ter superfícies de interação de fluxo formadas em ambas as extremidades destes pólos de campo. Estas superfícies estão localizadas adjacentes às superfícies magnéticas confrontantes para definir os entreferros de funcionamento, os 'quais são geralmente curvos na forma.
