Abstract

SUPORTE DE ROTOR, ROTOR, MOTOR E TURBINA EÓLICA. As modalidades do presente pedido fornecem um suporte de rotor, um rotor, um motor e uma turbina eólica. O suporte de rotor compreende um jugo magnético (1) e uma porção de reforço (2) fornecida em uma primeira face lateral (11) do jugo magnético (1); uma segunda face lateral (12) do jugo magnético (1) é configurada para dispor de modo operável um ímã de um rotor; a porção de reforço (2) cobre cada área de circuito magnético, o que pode gerar um circuito magnético parcial, da primeira face lateral (11); a soma das espessuras radiais da porção de reforço e do jugo magnético (1) sobreposto é maior que uma espessura pré-definida, e a espessura radial do jugo magnético (1) é menor que a espessura pré-definida. Em comparação com a técnica anterior, o suporte de rotor fornecido pelas modalidades do presente pedido pode alcançar a finalidade de aumento da espessura para reduzir a magnetorresistência, satisfazer as exigências para a densidade de fluxo de caixa de ar de um motor, e também reduzir de modo eficaz o peso dos suportes de rotor.
