The flabellum of heat dissipation；During the flabellum rotation, the wind pressure of the same direction is generated.
Preferably, the end cap is cylinder, and bore periphery is equipped with bearing mounting hole, the end cap on the inside of the end cap
Periphery is equipped with upper and lower perforative screw through-hole.
Preferably, the flabellum is five.
Preferably, the regulating tank for regulation motor weight balancing is equipped on the outside of the end cap.
Preferably, the regulating tank is circular ring shape regulating tank.
Preferably, it is waveform that the circular ring shape, which adjusts groove sidewall,.
Compared with prior art, the utility model at least has the advantages that：The utility model housing；It is arranged on institute
State the end cap that housing both ends are connected with the housing；And be inserted into from shell one end end cap, it is passed through from housing other end end cap,
Through the screw of the housing.Using above design, screw is from a side end cap through another side end cap, and screw middle section is leaned on
Permanent magnet adsorbs, while magnetite can substantially increase the connection between housing and end cap against screw rod, good reliability when rotated
Intensity.

Structure diagram.
Fig. 4 is a kind of sectional view of external rotor electric machine shell of the utility model preferred embodiment.
Specific embodiment
The utility model is described further with reference to the accompanying drawings and examples.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, present embodiment discloses a kind of companies of the connection structure of external rotor electric machine shell
Binding structure, which is characterized in that the connection structure of the external rotor electric machine shell includes：
Housing 1；
It is arranged on the end cap 2 that 1 both ends of housing are connected with the housing；And
It is inserted into from 1 one end end cap 2 of housing, is passed through from housing other end end cap, through the screw 8 of the housing.
Specifically, using above design, screw is from a side end cap through another side end cap, and permanent magnetism is leaned in screw middle section
Body adsorbs, while magnetite can be against screw rod, good reliability when rotated, and the connection substantially increased between housing and end cap is strong
Degree.
Preferably, several blocky permanent magnets 9 are equipped in the housing, the permanent magnet is arranged on 8 both sides of screw, to screw
8 play suction-operated, while magnetite can be against screw rod, good reliability when rotated.
Preferably, the end cap 2 is equipped with the through-hole 3 passed through for fixing axle；
3 periphery of through-hole is equipped with the flabellum 4 for radiating in housing 1；
When the flabellum 4 rotates, the wind pressure of the same direction is generated；
When housing 1 rotates, end cap 2 is driven to rotate together, so as to which flabellum 4 be driven to rotate, accelerate air pair in housing 1
Stream.
Specifically, flabellum 4 is fixed on end cap 2, rotated together with housing 1, during rotation one end into
Gas, one end outlet accelerate air flowing in housing 1, meanwhile, reduce parts, it is easy for installation.
Preferably, the end cap 2 is cylinder, and 3 periphery of side through hole is equipped with bearing mounting hole 5 in the end cap 2, described
2 periphery of end cap is equipped with upper and lower perforative screw through-hole 6.
Specifically, end cap 2 and housing 1 are fixed by screw.
Preferably, the flabellum 4 is five.
Preferably, 2 outside of end cap is equipped with the regulating tank 7 for regulation motor weight balancing.
Specifically, after installation is complete in motor, may motor be caused due to the installation site deviation of motor internal parts
