Abstract: Introduced a multi-objective optimization design method for motors using Maxwell and OptiSLang. The initial design scheme of the motor is determined by using the main size formula. Within the given design boundaries, sampling experiments are conducted using the Latin Hypercube method to generate the best predictive models. Based on the predictive models,the evolutionary algorithm is used to optimize the initial design scheme. After optimization, the efficiency of the motor increases by 0. 6% and the cost decreases by 11. 9%. A prototype was manufactured and the test results were highly consistent with the simulation predictions, indicating the correctness of the optimization design method. This method has solved the problems of low power density and high cost of the existing permanent magnet synchronous motors for logistics belt conveyor pulleys.
