| Abstract: | The basic structure and working principle of a new type of permanent magnetic actuator,namely the non-plane contact permanent magnetic actuator,is presented. Such a permanent magnetic structure can produce magnetic field with high axial gradient,so the dynamic response ability of coil magnetic field to moving iron-core can be remarkably improved to achieve the aim of increasing the initial velocity of the moving iron-core; meanwhile,the differences between basic working principle of double-acting vacuum int... |
