Specific implementation mode
The present invention is explained in detail below in conjunction with the accompanying drawings.
A kind of efficient D types dust catcher motor as shown in Figure 6, including rotor core 1, stator core 2, movable vane wheel 4,
Determine impeller 3 and fan housing 5, the coiling on the rotor core 1 and stator core 2, the rotor core 1 includes mandrel
11, as shown in Figure 1 on 11 surface of mandrel it is protruding it is several in T-shaped external part 12 for limiting coiling
Group, the external part 12 be uniformly distributed and positioned at mandrel 11 in the radial direction, external part 12 described in adjacent two it
Between be winding slot 13, the size of winding slot 13 and the density of coiling directly determine the efficiency and electric energy of motor heat dissipation
Utilization rate, the external part 12 are 12, and the angle between the 13 both sides contour line of winding slot is 30 °, the core
The outer diameter of axis 11 is 18.5mm, and the outer diameter of the rotor core 1 is 34.1mm, and the width of the external part 12 is 2.4mm.
The copper factor of coiling is directly had dropped 30% by the change of above structure than before, can improve the utilization rate of electric energy, reduces damage
Consumption.13 slot bottom of winding slot is arc-shaped, and angle is 64 °, a diameter of 3.2mm of arc, in the T of T-shaped external part 12
Prefix root is fillet, can preferably protect coiling not scratch.
Stator core 2 as shown in Figure 2 on the basis of the original, makes an adjustment the arc 21 on its four angles, Jiang Qijiao
Degree becomes smaller, and becomes 16 °, the radius of arc 21 is 35mm.The benefit made in this way essentially consists in, and angle formed by arc 21 becomes
It is small, so that the gap between stator core 2 and the shell of motor becomes larger, facilitate air circulation, so that heat dissipation performance
More preferably.
The silicon steel that rotor core 1 and stator core 2 are all made of B35A300 is made, according to performance of silicon steel itself, energy
Enough improve the efficiency of motor.
The blade 31 for determining impeller 3 as shown in Figure 3 is reduced to 16 from original 17 and is uniformly distributed, and increases in specific distribution
Gap between big blade 31 so that air duct becomes larger, while blade 31 is in gradual change type arc, and the rounder and more smooth air duct of radian is more
Smoothness, what air can be more smooth passes through air duct；It is 9 that the blade 41 of movable vane wheel 4 as shown in Figure 4 increases from original 8
And be uniformly distributed, the quantity of blade 41 increases 1, increases 1 air duct, makes movable vane wheel 4 in unit interval sucking, discharge
Air quantity increases, while blade 41 is in gradual change type arc, and radian is rounder and more smooth, and what air can be more smooth passes through air duct.Movable vane
The air of sucking is discharged wheel 4 by determining impeller 3, in order to ensure its efficiency, therefore needs the air capacity for sucking with being discharged equal, so
And existing technology, the discharge capacity of air are less than the soakage of air, so in use, can be arranged residual air in wind turbine
It does not go out, to influence the soakage of air, and then influences electric efficiency；The present invention by determine impeller 3 blade 31 and
The change design of the blade 41 of movable vane wheel 4, the discharge capacity for determining 3 air of impeller is more than the soakage of 4 air of movable vane wheel, to ensure that
Air will not be detained in wind turbine, therefore ensure that the balance of sucking and discharge, to reduce loss, improve the efficiency of motor.
5 air inlet of fan housing as shown in Figure 5 forms an annular groove 51, and silica gel is added in the annular groove 51,
In the upper port insertion silica gel of the movable vane wheel 4, the depth design of annular groove 51 is 4mm, and the silica gel depth of filling is also
4mm, in order to facilitate embedded silica gel, the height of fan housing 5 is designed as 38mm, and tolerance is ± 0.1mm.By in annular groove 51
Fill up silica gel so that almost without gap between fan housing 5 and movable vane wheel 4, the leakproofness between movable vane wheel 4 and fan housing 5 is improved,
Vortex will not be formed, reduces loss, effectively improves vacuum degree, increase suction, improves the efficiency of motor of dust collector.And
It is determined by its chemical composition and physical arrangement using silicone filler, with nontoxic, moisture absorption antirust, cohesive force
By force, high temperature resistant（1500 DEG C~1600 DEG C）, stable chemical performance, have the characteristics that stronger mechanical strength.
In conclusion by the Curve guide impeller to rotor core 1,2 structure of stator core, copper factor is had dropped 30%, with
Motor housing gap becomes larger, and facilitates heat dissipation, improves the utilization rate of the energy；By determining impeller 3 and the movable vane after improvement after improvement
The combination of wheel 4, when motor operation, the air quantity of the sucking of unit interval inner blower and discharge reaches balance, is not in that air is stagnant
Stay phenomenon；Fan housing 5 after improvement improves almost without gap between fan housing 5 and movable vane wheel 4 between movable vane wheel 4 and fan housing 5
Leakproofness, reduce loss, effectively improve vacuum degree, increase suction；By above-mentioned to motor internal components
Improvement, efficiency is increased to 44%~45% from original 33%~35%.
It is emphasized that：It the above is only presently preferred embodiments of the present invention, not the present invention made in any form
Limitation, it is every according to the technical essence of the invention to any simple modification, equivalent change and modification made by above example,
