PURPOSE:To change freely stirring speed depending upon position of a container, by constituting plural motors consisting of plural rotors which are set on the same shaft inside the container in the direction of the revolving shaft, and plural stators which are set outside the container and have pairs with the rotors. CONSTITUTION:The rotors 12a and 12b are set on the same shaft at vertical two steps in the non-magnetic and nonelectrically-conductive container 10, and the stators 14a and 14b are laid outside the container 10 in such a way that the peripheral wall of the container 10 is sandwiched between the stators and the rotors, and the stators are opposed to the rotors 12a and 12b. The agitating blade 18 is fixed to the rotary shaft 16 attached to the rotor 12a, and the agitating blade 20 is fixed to the rotors 12b. The rotational speed and rotational direction of the agitating blades 18 and 20 can be set independently. |
