Abstract
The system and method of the invention pertains to an axial flux stator is implemented to replace the drive-end magnets and the drive motor. The axial flux stator comprises a control circuit to control the voltage and current provided to the stator, to measure the torque and speed of rotation, and to measure the magnetic flux and magnetic flux density produced by the axial flux stator and impeller magnets, individually or in combination. The axial flux stator comprises a plurality of current carrying elements to produce magnetic flux in an axial direction and drive the impeller.
Claims10
A magnetic mixing system, comprising:
- a mixing vessel;
- a magnetic impeller inside the mixing vessel;
- a magnetic drive head outside the mixer vessel, wherein movement of the magnetic drive head enables torque transfer and thus rotation of the magnetic impeller;
- and
- one or more magnet sensors positioned between the magnetic drive head and the impeller that is configured to detect the magnetic field or a magnetic flux.
