Abstract: A new generation of integrated wheel hub motor was developed for the application of the wheel hub system of the electric vehicle. According to the design requirements, the overall design scheme of the outer rotor wheel hub motor was given, and the main ruler and the whole electromagnetic structure were analyzed and calculated. The influence factors of magnetization direction length, pole arc coefficient, air gap length and stator lamination were analyzed by using Ansoft software to improve the output performance of the motor. Finally, the prototype was calculated and tested. The design results are in agreement with the experimental results, which shows the correctness of the design analysis.
Key words: outer rotor hub motor; main dimensions; length of magnetization direction; pole arc coefficient; air gap length; stator stack height
