The invention discloses a coaxial double-paddle rotor salient pole motor propulsion power system structure which comprises a stator and a rotor, wherein the stator and the rotor are both of a salient pole structure, the rotor and the stator rotate relatively, and an annular air gap is formed between the stator and the rotor; the stator and the rotor adopt skewed slot structures, and skewed slots are consistent in direction; rotor teeth outside the rotor are an outer paddle, and rotor teeth inside the rotor are an inner paddle; and the two axial sides of the motor are provided with annular hollowed-out bearings used for fixing the motor, and stable operation of the motor is guaranteed. The total diameter of the paddles can be effectively increased, a complex transmission shaft system is omitted, the unit space utilization rate is increased, the propelling capacity of a power system is enhanced, and the characteristics of light weight and high efficiency are achieved. Meanwhile, a permanent magnet and the like on the original rotor are eliminated. The rotor strength is improved, and the rotor can better adapt to various rotating speed occasions.

    本发明公开了一种同轴双桨的转子凸极电机推进动力系统结构,包括均为凸极结构的定子和转子,转子和定子相对转动,定子与转子间形成环形气隙;所述定子和转子采用斜槽结构,斜槽方向一致;所述转子外的转子齿为外桨叶,转子内为内桨叶;所述电机轴向两边为环状镂空轴承用于固定电机,保障电机的稳定运行。本发明能有效增加了桨叶的总直径,取消了复杂的传动轴系统,提高了单位空间利用率,增强动力系统的推进能力,具有轻量化和高效率的特点。同时取消了原本转子上的永磁体等。提升了转子强度,可以更好适应各种转速场合。
