Description

Technical Field

[0001] The utility model relates to the field of magnetic stirring, in particular to a magnetic stirring system. Background Art

[0002] Magnetic stirring is the use of magnetic force to perform rotational stirring. The common magnetic stirring system generates magnetic lines of force by the operation of the drive motor, and uses the magnetic force between the magnetic lines of force and the rotor made of magnetic material to drive the rotor to rotate, thereby forming a stirring force at the bottom of the solution to achieve the purpose of stirring the solution.
