Abstract

"ATUADOR ELETROMAGNéTICO" Um atuador eletromagnético para mover um contato para um estado de ligado ou desligado, compreendendo uma haste de atuação do contato deslocável ma direção longitudinal entre uma primeira posição correspondendo ao estado desligado, e uma segunda posição, correspondente ao estado ligado. Um núcleo feito de material magnetizável e que interage com uma bobina de ligação é adaptado à haste de atuação do contato. Uma peça de polo também estando presente, a qual é feita de material magnético e da qual a face voltada para o núcleo, na primeira posição da haste de atuação do contato, é arranjada a uma distância de intervalo de ar daquela superfície do núcleo que é direcionada perpendicularmente à direção do deslocamento e, na segunda posição, fica tão próximo quanto possível da mencionada superfície de núcleo. Além disso, o atuador compreende um garfo, feito de material magnetizável, para fechar o circuito de fluxo magnético da bobina de ligação através da peça de polo e o núcleo. Um dispositivo de imã permanente é usado para manter a haste de atuação do contato na primeira posição, enquanto uma mola pré-carrega a haste de atuação do contato, em sua segunda posição, para a primeira posição. O atuador é provido de uma bobina de desligamento que, para a finalidade de mover a haste de atuação do contato da segunda posição para a primeira posição, é excitada para eliminar o campo magnético do dispositivo de imã permanente ao menos temporariamente, o circuito de fluxo magnético do dispositivo de imã permanente sendo separado daquele da bobina de ligação.
