[Objective] In traditional electromagnetic field simulation software
numerical calculation methods such as finite difference and finite element method are mainly used to solve problems. Although these methods can obtain numerical solutions closer to the experimental results
their computational accuracy heavily depends on the number of meshes and the quality of the dividing. While improving the solution accuracy
it also leads to a significant in computation time and cost
especially when using software for large-scale optimization design. [Methods] Therefore
this paper proposed a development strategy for electromagnetic simulation software that integrated artificial intelligence technology. Artificial neural network (ANN) models were used in pre-processing
solving
and post-processing to accelerate the entire solving process. In the modeling process
multimodal parametric modeling techniques based on images
speech
and text were used. In the mesh dividing and matrix solving
ANN models were used for classification judgment or regression prediction. In the processing and visualization stages of calculation results
machine learning fitting and interpolation methods were used for smoothing the computational results and improving the resolution. [Results] Based on electromagnetic simulation software
a large amount of finite element data could be obtained for specific problems. In a data-driven environment
it was possible to achieve the prediction of electromagnetic field distribution
the prediction of AC copper consumption based on surrogate models
the full performance prediction of motors with multiple input/output and operating conditions
multi-objective accelerated optimization with the help of classifiers
as well as multi-objective optimization and motor modeling based entirely on surrogate models. [Conclusion] This study constructs digital twins of electromagnetic products through data-driven approaches
providing effective support for their status monitoring
predictive maintenance and performance optimization.
