The connection of motor 20 and unmanned vehicle 1000 is realized on the horn 300 of device 1000.In some embodiment of the invention, stator seat
Do not have to be used for the engraved structures such as heat emission hole, the radiating groove of heat dissipation in the prior art on 221, further enhances the anti-of motor 20
Water, anti-dust performance.In further embodiments, the hollow hole for heat dissipation can also be arranged in stator seat 221, in order to enhance waterproof
Performance, can be in stator seat 221 and 300 joint of horn setting fluid sealant or sealing ring.
The shell 211 of rotor assembly 21 covers at stator seat 221 by its cylindrical portion 2112 and covers iron core 222 and coil
2221, and projection of the stator seat 221 in the plane perpendicular to motor shaft 212 is located at shell 211 perpendicular to motor shaft 212
Plane on projection in.For example, in some embodiments, in the horizontal direction, the maximum outside diameter of stator seat 221 is less than shell
211 maximum outside diameter, stator seat 221 are fully located in the region that shell 211 is provide with, and are reached without any one part outer
Outside shell 211.In some embodiment of the invention, the pedestal 2211 of stator seat 221 includes bottom wall 22112 and from bottom wall 22112
The lateral wall 22111 that outer extends, lateral wall 22111 have the maximum outside diameter of stator seat 221.As shown in fig. 7, stator seat
221 only a portions are located in cylindrical portion 2112, are blocked by cylindrical portion 2112.In some other embodiment, stator seat
221 can be entirely located in cylindrical portion 2112, that is, the lateral wall 22111 of stator seat 221 can all be hidden by cylindrical portion 2112
Gear.When rainwater is fallen from top to down, can be fallen along the lateral wall 2211 of shell 211, without being flow to along shell 211
Stator seat 221, and then the inside of motor 20 is flowed into, it is such to design the waterproof effect for enhancing motor 20.
Meanwhile in order to enable 21 relative stator component 22 of rotor assembly to rotate, without the blocking by stator module 22,
The internal diameter of the cylindrical portion 2112 of rotor assembly 21 is configured to the lateral wall 22111 of the stator seat 221 more than stator module 22
Outer diameter does not contact each other so as to have gap between rotor assembly 21 and stator module 22.In further embodiments, in order to
Avoid the oversized of cylindrical portion 2112, can also only by cylindrical portion 2112 close to the part of lateral wall 22111 be arranged to outside
Side wall 22111 has gap, does not contact each other.In some embodiment of the invention, as shown in fig. 7, cylindrical portion 2112 is close to outer
The part of side wall 22111, that is, the lower end of cylindrical portion 2112 is configured to the lateral wall with pedestal 2211 in the vertical direction
There are gap h between 22111 upper surface, in the horizontal direction between the surface of the lateral wall of pedestal 2,211 22111 there are
Gap d, under the premise of the size of cylindrical portion 2112 will not be excessive, ensure that between cylindrical portion 2112 and stator seat 221
With gap, do not contact each other.In practical applications, d can with value 0.1mm or 0.1mm or more, h can with value 0.2mm or
0.2mm or more.
