Abstract

a presente invenção refere-se a um atuador eletromagnético giratório (2) que inclui uma montagem de inclinação (30) para aplicar um torque a seu rotor (4). tal atuador pode ser usado para operar uma válvula de gatilho de um motor de combustão interna. a montagem de inclinação é comutável entre (a) uma primeira configuração, em que a montagem de inclinação exerce um torque no rotor sobre pelo menos parte da faixa de rotação do rotor, em que o torque exercido varia com a posição de rotação do rotor de acordo com um perfil de torque, e (b) uma segunda configuração, em que a montagem de inclinação exerce substancialmente nenhum torque no rotor sobre a faixa de rotação do rotor.
