Abstract

a presente invenção refere-se a um grupo magnético (10), com um núcleo do eletroímã (11) e uma luva do eletroímã (25) que o aloja, e com uma armadura do eletroímã (35) atuando em conjunto com o núcleo do eletroímã (11), disposto de modo longitudinalmente deslocável ao longo de um eixo longitudinal (16) da luva do eletroímã (25), a qual, na sua posição final, sob a formação de uma abertura de ar residual (32), é disposta em uma superfície frontal (33) do núcleo do eletroímã (11) oposta à armadura do eletroímã (35). de acordo com a presente invenção é previsto que a luva do eletroímã (25) apresenta um segmento de fixação (28) que se projeta radialmente em direção ao eixo longitudinal (16) para a fixação axial do núcleo do eletroímã (11), com um segmento de distância (30) disposto em sobreposição radial com a armadura do eletroímã (35), para o ajuste da abertura de ar residual (32).
