There are gap h between end face, and there are gap ds between the surface of the lateral wall of pedestal 2,211 2213 in the horizontal direction, thus
Under the premise of the size of cylindrical portion 2112 will not be excessive, ensure that has gap between cylindrical portion 2112 and stator seat 221, that
This is not contacted.In practical applications, d can be with value 0.2mm or 0.2mm or more with value 0.1mm or 0.1mm or more, h.
In some embodiments, cylindrical portion 2112 has the first internal diameter in one end far from stator seat 221, close to stator
One end of seat 221 has the second internal diameter more than first internal diameter, and the second internal diameter is more than the maximum outer of the stator seat 221
Diameter, that is, the second internal diameter is more than the diameter of the lateral wall 2213 of the stator seat 221.Wherein, the second internal diameter of cylindrical portion 2112 with
The size of the difference of the diameter of the lateral wall 2213 is the size of above-mentioned gap d.Specifically, in some embodiments, tubular
The madial wall in portion 2112 includes first madial wall 2115 with first internal diameter, from the first madial wall 2115 to far from motor
Step wall 2116 that the direction bending of axis 212 extends and being bent from step wall 2116 extends and the with second internal diameter
Two madial walls 2117.The lateral wall 2213 of the stator seat 221 is at least partially housed in shown second madial wall 2117.Institute
State step wall 2116 and the lateral wall 2213 towards being equipped with above-mentioned gap h between the upper surface of step wall 2116.To,
Ensure that has gap between cylindrical portion 2112 and stator seat 221, do not contact each other.
In order to further strengthen the water resistance of motor 20, Figure 14 is please referred to, at least one can also be machined on shell 211
A water-carrying groove 2110 axially extending along motor shaft 212, so that the rainwater into motor 20 can be flowed out by water-carrying groove 2110.
Water hole (not shown) can also be set on motor shaft 212, such as be arranged in the center of motor shaft 212, with into one
Step provides the channel of rainwater outflow, increases water resistance.
In some embodiments of motor 20, in order to improve heat dissipation performance, radiating vane can also be set in motor 20.
The radiating vane can be contained in shell 211 in one of the embodiments, for example, being set to iron core 222, coil
In the space of 2221 tops.Radiating vane is fixed on shell 211, and when shell 211 rotates, radiating vane can be with shell
211 rotations think that motor 20 radiates.In some embodiments, radiating vane can be sheathed on motor shaft 212, work as motor shaft
When 212 rotation, radiating vane can be rotated with motor shaft 212.
In further embodiments, Figure 14 is please referred to, the extension pedestal extended downwardly can be set below pedestal 2211
2215, radiating vane can be located in the inner space of the extension pedestal 2215, be consolidated motor 20 by the extension pedestal 2215
