Head maximum capacity is less than 1M3/min；Oil spout or the single-head maximum capacity about 3M of water spray scroll air compressor3/ min, this is
Whole world compressor industry thinks that screw compressor is difficult to substitute other high energy consumptions, more this place of high noisy compressor, exceedes
The scroll air compressor of above discharge capacity is combined by several.
The structures shape of the scroll compressor type does not allow that compressor part is metal heated to be caused in compression process
Thermal expansion it is excessive, be typically only capable within 0.05mm, not so in compression motion process, being vortexed between dynamic price fixing seriously to do
Abrasion is related to, until killing breaking-up.This scroll molded line for also resulting in scroll air compressor can not be high, makes the capacity of screw compressor
It is extremely limited, especially oil-free vortex compressor cannot more overcome the restriction of capacity, cause oil-free vortex pressure
The advantages of low noise, high reliability, low energy consumption of contracting machine, cannot well play a role in compressor application field.This is not only
Compressor in the industry sorry, is also the disappointment of vast compressor user.But either energy consumption, noise, reliability, volume are isobaric
What the quality of the indices of contracting machine, especially oil-free vortex compressor was represented is the compressor type of latest generation, is broken through
The restriction of discharge capacity becomes the expectation in row.
The content of the invention
The purpose of this utility model is to provide a kind of oil-free vortex air compressor machine external rotor electric machine, is opened up on rotor disk
Circulated air aperture, the high pressure cooling air that fan assembly is formed can flow through again little from circulated air from rotor with the gap of stator
Centrifugal fan intake region is returned at hole, the process can take away the heat turned from producing with stator, can also pass through circulated air
The quantity and pore size of aperture is adjusting the cooling air delivery by stator and rotor.
To realize above-mentioned technical purpose, above-mentioned technique effect is reached, the utility model discloses a kind of oil-free vortex is empty
Press external rotor electric machine, external rotor electric machine is assemblied on oil-free vortex air compressor host main shaft, is driven by controller,
Rotor part and stator component are included, rotor part is arranged on main shaft, is placed within volute, and stator component is arranged on volute
End face, rotor part and the ratcheting formation air compression chamber of stator component.
Wherein, rotor part includes fan assembly, rotor disk, magnetic guiding loop, permanent magnet and bushing, and bushing is nested in sky
On press main frame main shaft, bushing has been orderly arranged outside each permanent magnet and magnetic guiding loop, and rotor disk is coated on magnetic guiding loop outside, rotor
Some circulated air apertures are offered on wheel disc, fan assembly is arranged at the dorsal surface of rotor disk.
Wherein, stator component includes stator casing and stator core, stator casing and rotor disk mutually ratcheting formation
Air compression chamber, stator casing is coated on stator core outside.
Wherein, fan assembly is axial flow blower or centrifugal blower, and fan assembly Leaf exit installation angle is 30-55 °.
The utility model has the advantages that：
1. the utility model has opened up circulated air aperture by Optimal Structure Designing on rotor disk, and fan assembly is formed
High pressure cooling air can flow through from the gap of rotor and stator and return to from circulated air aperture again fan assembly air-breathing area
Domain, the process can take away the heat turned from producing with stator, can also be adjusted by the quantity of circulated air aperture and pore size
Section is by stator and the cooling air delivery of rotor.
2., through the external rotor electric machine of appropriate design, fan assembly Leaf exit installation angle is 30-55 °, makes gas dirt
The incidence angle of grain avoids 20-30 ° of angle of blade wear most serious as far as possible, improves the life-span of blade.

Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to the utility model.
As Figure 1-3, the utility model discloses a kind of oil-free vortex air compressor machine external rotor electric machine, external rotor electric machine
It is assemblied on oil-free vortex air compressor host main shaft 1, is driven by controller, includes rotor part and stator department
Part, rotor part is arranged on main shaft 1, is placed within volute 2, and stator component is arranged on the end face of volute 2, rotor part and stator
Part is ratcheting to form air compression chamber.
Rotor part includes rotor disk 3, magnetic guiding loop 4, permanent magnet 5, bushing 6 and fan assembly 8, and bushing 6 is nested in
