[0032] As shown in Figure 1 and Figure 2 The embodiment of the present application provides an electric machine component, which mainly comprises a machine body 1, an impeller 2 and an air guide wheel assembly.

[0033] The impeller 2 comprises a cover 21 and a plurality of blades 22 arranged around the cover 21, the cover 21 at least wraps one end of the motor shaft 11 of the machine body 1 and is connected with the motor shaft 11 of the machine body 1, the machine body 1 can drive the impeller 2 to rotate, and the cover 21 is provided with a wind guide hole 23.

[0034] It should be noted that the cover 21 at least wrapping one end of the motor shaft 11 of the machine body 1 can be understood as that the cover 21 forms a containing cavity structure, and at least one end of the motor shaft 11 of the machine body 1 extends into the containing cavity, when the external wind enters the cover 21, the wind can blow to the machine body 1 to cool it. Of course, in some embodiments, the cover 21 can also wrap the entire machine body 1.

[0035] The wind guide wheel assembly is arranged in the cover 21, and the wind guide wheel assembly comprises a wind wheel 3 and a driving member for driving the wind wheel 3 to rotate, under the condition that the driving member drives the wind wheel 3 to rotate, the external wind can enter the cover 21 through the wind guide hole 23 to exchange heat with the machine body 1.

[0036] In the motor component of the embodiment, the wind guide wheel assembly is arranged in the cover 21, when the wind guide wheel assembly rotates, the external wind can be introduced into the cover 21 through the wind guide hole 23 on the cover 21, so that the wind directly flows through the machine body 1, the machine body 1 is cooled, the effective use power of the machine body 1 is improved, and the foreign matters around the machine body 1 are removed, the service life of the oil seal of the motor shaft 11 of the fan is improved.

[0037] As shown in Figure 3 in some embodiments, the wind wheel 3 is sleeved on the motor shaft 11 of the machine body 1 and can rotate with the motor shaft 11, and the motor shaft 11 forms the driving member, so that the structure can be simplified, thereby avoiding the separate arrangement of the driving member to occupy additional space.

[0038] As shown in Figure 3 in some embodiments, the wind wheel 3 comprises a wheel shaft and a plurality of wheel blades arranged radially around the wheel shaft, and each wheel blade is coplanar with the motor shaft 11.
