【Abstract】To addressthe issues of AC copper lossin flat wire windings and low torque of amorphous alloy cores，a structural parameter model is establishedusing finite element software.With theoptimizationobjectives ofincreasing average torque，educingACcopperloss，anddecreasingtorqueripple，keydimensionalparametersare extractedbasedonsensitivity analysis.Subsequently，multi-objectiveoptimizationdesignandsingle-parameterscaningareconducted incombination with the particle swarmoptimization algorithm inspired bywild gooseformation（WGA-PSO）.The motor performancebeforeand afteroptimizationiscomparedthroughfiniteelementsimulation.Theresultsshowthatafteroptimization，theaveragetorqueof the motor increases by 5% ，the torque ripple decreases by 12% ，and the AC copper loss reduces by 8% .Finally，aprototype is manufactured and tested，which verifis thecorrectness of the simulation results.
