Abstract: Designed Permanent magnet synchronous in-wheel motor Adopt finite element method in.Optimized the air-gap flux-density harmonics and the cogging torque parameter,which affected the performance of in-wheel-motor.Reduced the harmonic losses and torque ripple,so high speed,good control performance and high power density characteristics had been realized,and the performance of in-wheel-motors had also been improved.Expanded its speed and torque range using fluxweakening control in the in-wheel-motor.At last a inner in-wheel-motor prototype had been made,then testing its performance,the results illustrate the performance of the prototype can meet the design requirements.
