Electric wheel is a key technology of distributed power system for the next generation of electric vehicle. Based on the analysis of several typical structures and features of the electric wheel,we point out that integrated in-wheel direct driving is the development trend of electric wheel technology. In view of the weakness with the existing in-wheel driving scheme,we suggest a novel integrated electric wheel driven by single disc permanent magnet synchronous motor（ PMSM）. We then carry out the research of 3D electromagnetic field of the in-wheel disk PMSM with finite element analysis method,and analyze the mechanical features of the novel type of wheel. This type of novel wheel has such strengths as higher degree integration,high torque,and light in weight,which establishes the solid foundation for the further development of the proposed structure.
