Problems solved by technology

The laminated structure is generally assembled by 4 to 6 sets of independent iron cores, the primary eddy current loss is reduced, but its structure is complex and difficult to assemble
The horizontal lamination type and the silicon steel sheet type are simple in structure, easy to manufacture, and are also widely used. The main disadvantage is that the eddy current loss of the iron core is large, which greatly reduces the efficiency of the motor.
The eddy current loss of the laminated window structure is small, but the processing cost is high
[0005] The traditional linear induction motor not only has the above-mentioned serious current loss problems, but also has a bloated device and limited structural form, so it cannot be used in miniature or complex equipment.
In view of the above technical problems, it is a technical problem to be solved urgently to provide a new type of conductive liquid micro-drive method that can overcome the defects of the above-mentioned devices that are bloated and have limited structural forms.
