Abstract

Dispositivo e método para refrigerar os núcleos do rotor e do estator de um motor. A presente invenção refere-se a um núcleo laminado (10) para um motor inclui uma pluralidade de lâminas (12), cada uma das quais estando disposta em uma relação não afastada, e cada uma das quais apresentando uma configuração em forma de disco, e sendo que cada uma dentre a pluralidade de lâminas (12) é dimensionada e configurada de modo a permitir que um fluxo de refrigerante de desloque em uma direção radial em relação ao eixo de rotação do motor. Também é apresentado um método de refrigeração de um motor.
