Problems solved by technology

The result of traditional magnetic circuit design is not accurate enough. Although the method of parametric finite element analysis can achieve better design accuracy, due to the large number of design target parameters and the complexity of the optimization process, the design cycle will be greatly increased and the optimization efficiency will be reduced.
In addition, it is difficult to quickly analyze and describe the influence relationship between each optimization parameter and the optimization goal with the method of enumerating parameterization
