Specific embodiment
In order to keep the method for the utility model clearer, clear, make below in conjunction with specific embodiment, attached drawing further
It is described in detail:
The utility model embodiment, as shown in figs. 1-7:
Electronic ducted-fan blower includes duct 02, rotor 03, stator 01, rear cover 04.
It is bearing chamber that duct 02, which includes among 22,22 inner cylinder of outer cylinder 23 and inner cylinder, is 6 equal between outer cylinder 23 and inner cylinder 22
The stator blade 21 of even distribution.
Rotor 03 includes axis 34, impeller 31, bearing 32, magnet ring 33.
Impeller 31 is fixed on the leading portion of axis 34, and magnet ring 33 is permanent magnet, after magnetizing on cylindrical surface formed the pole N,
One pole S, magnet ring 33 are fixed on the back segment of axis 34, and bearing 32 is fixed between impeller 31 and magnet ring 33, and the rearmost end of axis is fixed
There is bearing 32.
The rear end of duct 02 is fixed with rear cover 04, there is bearing chamber (not individually instruction in figure) among rear cover 04.
Two bearings 32 of rotor 03, frame is in the central bearing chamber (individually instruction in figure) with rear cover 04 of duct 02 respectively
It is interior, it can rotate.
Stator 01 includes iron core 13, coil 12.
Iron core 13 is tubular permeability magnetic material, has insulating layer (not shown), coil between 13 inside of iron core and coil 12
12 are made of enameled wire, and are divided into three-phase, are fixed on the inside of insulating layer (not shown).
Electric machine controller 09 is the three-phase brushless motor controller of no sensor, is connect by conducting wire 08 with coil 12.
When work, 09 control coil 12 of electric machine controller is powered, and drives magnet ring 33 to rotate by stator 01, final to drive
Impeller 31 rotates.The air-flow that impeller 31 generates, is guided by stator blade 21, is sprayed from the tail portion of duct 02.
Since 13 inner surface of iron core is one complete round, 33 outer surface of magnet ring is also one complete round, mutually
Between there is no a slot effect, when rotation, is very smooth.
In addition, iron core 13 is annular, without the line embedding groove of general motor since coil 12 is fixed on 13 inner surface of iron core.
When work, coil 12 is exposed under the air-flow in duct, and it is very good to radiate, and higher power may be implemented.
The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model,
Equivalent structure transformation made by using the description of the utility model and the drawings is applied directly or indirectly in other phases
The technical field of pass, is also included in the patent protection scope of the utility model.
