Abstract

"MOTOR ELéTRICO DE íMã PERMANENTE GIRATóRIO COM FOLGA DE AR VARIáVEL ENTRE ELEMENTOS DE ESTATOR E ROTOR INTERFACEANTES". A presente invenção refere-se a um motor de imã permanente que está configurado com uma variação seletiva da distância radial entre um par de ímã permanente de rotor e pólo de estator interfaceantes ao longo do comprimento circunferencial do par. Os efeitos do torque de engrenamento na característica de torque total podem ser controlados pela determinação de um perfil de variação de folga de ar apropriado. As superfícies do pólo de estator e do ímã de rotor podem ser inclinadas uma em relação à outra, o ângulo entre as mesmas sendo selecionado para obter uma compensação de torque de engrenamento desejada. Outros perfis de variação de folga de ar podem incluir a provisão de superfícies cóncavas, o grau de concavidade sendo selecionável.
