Summary:The invention discloses a permanent-magnet synchronous motor optimizing method which comprises the steps: obtaining all the optimization assemblies according to a value range of preset structure parameters of a permanent-magnet synchronous motor and a corresponding point obtaining amount; calculating out no-load gap flux density distortion rates and cogging torques of all the optimization assemblies and constructing a sample space; establishing a first fitting model of the no-load gap flux density distortion rates and a second fitting model of the cogging torques according to the sample space;performing dual-objective optimization on the first fitting model and the second fitting model through an optimizing algorithm to obtain the optimal compromise solution of the preset structure parameters; optimizing the permanent-magnet synchronous motor according to the optical compromise solution. The optimal compromise solution in the permanent-magnet synchronous motor optimizing method disclosed by the invention comp
