In this paper, optimum design for efficiency of ultra-high-speed permanent magnet synchronous motor for hydrogen fuel cell electric vehicle air blower is performed. First, the design factors that greatly affect the copper loss, iron loss and eddy current loss were selected using analysis of variance. Then, the experimental points were selected using the Latin hypercube sampling method, which is a statistical method for generating a near-random samples of the design factor values from a multidimensional distribution and the test was carried out using an electromagnetic finite element method. Based on the test results, the Gaussian process is used to optimize the efficiency. Finally, the loss and efficiency of the optimum model were verified by using finite element analysis.
