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, b
