<P>PROBLEM TO BE SOLVED: To provide a stirring method for reducing lateral load without lowering the number of revolution of a stirring member, and to provide a stirring member suitable for reducing of lateral load. <P>SOLUTION: The stirring method of a fluid in a fluid tank in which at least two rotary shafts 31 include parallel stirring members 10 comprises as follows. For example, as an electrical phase control method at starting, a rotation phase detector 32 which is prepared at the upper part of the rotary shaft 31, and detects the difference of phase with the stirring member which adjoins; a computing unit 33 into which information about the rotation phase from the detector is input as an electric signal; a starting controller 34 into which information about the optimal starting phase computed by the computing unit is input as an electric signal; and an electric motor 35 are included, wherein the starting controller 34 controls the starting timing of each of the stirring members using the optimal rotation phase obtained by the computing unit 33. <P>COPYRIGHT: (C)2012,JPO&INPIT |
