Abstract: Since the surrogate model method can significantly improve the efficiency of engineering design, it has been widely considered in various engineering optimization fields and gradually developed into a class of optimization algorithms. Among the existing surrogate model methods, the kriging surrogate model originating from geostatistics is a representative optimization method with potential applications. However, only a few researchers apply it to the field of motor design. In this paper, the equivalent circuit of the linear induction motor was firstly introduced, then the optimization framework of the kriging surrogate model was described, finally the kriging optimization method was adopted to optimize the linear induction motor.
