[0032] The rotor body 3 is rotatably connected to the stator body 4;

[0033] The driving shaft 2 is fixedly connected to the rotor body 3 .

[0034] The stator outer diameter is 145-380mm.

[0035] The number of stator slots is 24-72.

[0037] The outer diameter of the rotor is 75-260mm.

[0038] Reference Figure 4-Figure 6 By effectively increasing the outer diameter of the rotor body 3, the length of the fuselage 1 is shortened while ensuring power.

[0039] The number of rotor slots is 28-60.

[0040] Reference Figure 4-Figure 6 By effectively reducing the number of slots in the rotor body 3 and increasing the slot area of ​​the rotor body 3, the loss of the rotor body 3 and the drift load loss are reduced.

[0041] The inner diameter of the rotor is 22-85mm.

[0042] A fan 1011 is rotatably connected to the body 1 , and the fan 1011 is fixedly connected to the driving shaft 2 .

[0043] A cover 101 is fixedly connected to the body 1 , and a fan 1011 is disposed in the cover 101 .

[0044] Reference Figure 2-Figure 3 The cover 101 is provided with cooling windows, and the temperature rise of the fuselage 1 can be effectively reduced by setting multiple groups of cooling windows.

[0045] Reference Figure 2-Figure 3 An inspection window is provided at the center of the cover 101, and the size of the inspection window is 10 mm. By reducing the size of the inspection window, the safety hazard of the motor fan cover inspection window being too large and posing a risk of contact to a person is solved.
