Electromagnetic actuator and switch apparatus equipped with such an electromagnetic actuator |
摘要 |
An actuator comprising: a fixed part comprising a ferromagnetic yoke and a magnetized assembly mounted on a face of the yoke and extending substantially over the whole dimension of said face parallel to the axis of movement of a moving part, the moving part comprising a ferromagnetic element comprising a first air-gap surface to form a magnetic air-gap of variable thickness and a second air-gap surface parallel to the axis of movement to form a residual magnetic air-gap of constant thickness with a corresponding air-gap surface of the magnetized assembly. an excitation coil. An electric switch apparatus equipped with the actuator.
