Dual-motor coaxial different-direction dual-propeller structure of electric paramotor

A dual-motor coaxial different-direction dual-propeller structure of an electric paramotor, the structure comprising:

• a cylindrical mounting shaft with a central hole inside, wherein a first brushless motor is fixedly sleeved on the mounting shaft;
• a first blade assembly is rotationally sleeved on the mounting shaft;
• a second brushless motor is fixedly sleeved on the mounting shaft;
• a second blade assembly is rotationally sleeved on the mounting shaft;
• the first blade assembly is in transmission connection with the first brushless motor;
• the second blade assembly is in transmission connection with the second brushless motor;
• and during flight, the first brushless motor and the second brushless motor respectively drive the first blade assembly and the second blade assembly to rotate in opposite directions characterized in that a first stator assembly and a second stator assembly have the same structures and both comprise an annular stator winding fixed to the outer side wall of the mounting shaft and characterized in that a first rotor assembly and a second rotor assembly have the same structures and both comprise a rotor casing and two permanent magnet blocks, with different polarities, embedded in the rotor casing, and the rotor casing surrounds the stator winding inside and characterized in that the rotor casing comprises a first end casing, a middle casing and a second end casing, wherein the middle casing adopts an annular structure;
• the first end casing and the second end casing are detachably connected to openings in both ends of the middle casing;
• and through holes for the mounting shaft to penetrate are formed in the middles of the first end casing and the second end casing.
