Abstract:
     The invention discloses electromagnetic driver in magnetic suspension capable of controlling timing and lifting air gate. Electromagnets in multiple stages are placed in upper and lower inside outer shell of the driver. Changing directions of voltages input to individual electromagnetic generates repulsion force and attraction in order to drive sheath of valve stem on top most of the electromagnets. Being connected to valve stem, the sheath drives air gate to generate opening and closing operations.
