英文摘要：

The structure and characteristics of a new type of toroidal motor with hybrid excitation were introduced. Considering the special features of its space structure, the relationship between reduction ratio and the structural parameters was analyzed. The conditions need to meet for the structural parameters were given. The spiral trajectory equations of inner and outer stators were derived and an integrated scheme of the worm innerstator was proposed in this paper. The virtual assembly of experimental prototype was realized and the analysis model was established by FEM software, the air gap flux density was analyzed. The research results provide reference for further study on the performance of this motor.
