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.
