止できる効果を有する。(7) Effect of the Invention As described above, according to the first invention, the cup-shaped rotor having the stirring blade and the through hole on the upper surface is rotated in the casing made of a nonmagnetic material surrounding the stator. Since a plurality of pump blades are provided on at least one of the opposing upper surfaces of the rotor or the housing, the liquid supplied from the through holes on the upper surface of the rotor is supplied by the pump blades according to the rotation of the rotor. Entrained and pumped toward the periphery between the opposing upper surfaces of the rotor and the housing, increasing the hydraulic pressure to generate lift in the rotor, balancing the agitation reaction of the agitating blades on the outer periphery of the rotor with the lift. The rotor is smoothly rotated to efficiently stir the liquid in the container, and the treatment of the liquid after the stirring becomes extremely easy. According to the second invention, the labyrinth is provided on the opposed peripheral surface of the rotor or the housing. According to the rotation of the rotor, The liquid flowing in and supplied from the through hole on the upper surface of the rotor is restricted from flowing out between the opposed peripheral surfaces by the labyrinth,
Thus, the fluid pressure between the upper surface of the rotor and the opposing upper surface of the housing is increased, causing lift to occur in the rotor, smoothly rotating and effectively agitating the rotor in the same manner as described above, and further sealing and unsealing. It can be used irrespective of the container, has a simple structure, is easy to handle, and can be miniaturized, and can be agitated in high pressure and vacuum, and can suppress the consumption of rotating parts and the occurrence of vibration. Has an effect.
