The single phase induction motor with conventional distributed winding has a lot of disadvantages,such as complicated stator winding process,low slot fill factor,and long end-connection length etc.To improve these shortcomings,the possibility of single phase toroidal winding induction motor was studied,moreover the new structure of the motor and main points for designing the motor were also discussed.According to the working principle and the special structure of the single phase toroidal winding induction motor,Maxwell 2D,the finite element method software was used for modeling and simulation.The motor's transient performance,the starting performance,the output power and the efficiency of the motor were evaluated through the simulation model.The distribution and saturation of the iron core magnetic flux during the rated speed were also analyzed,which provides a reference for motor design.
