More and more higher, conventional D type motor increasingly cannot meet requirement and the society requirement to environmental conservation of people's low power consuming.
The D shaped iron core of existing conventional D type suction cleaner using motor, the space of its winding slot is less, and coiling causes copper factor
Too high, radiating effect is poor, and the efficiency of motor is between 33%～35%, and the utilization rate of electric energy is low, and loss is big；It determines impeller by 17
The uniform composition of sheet blade, the less draft capacity affecting unit interval inner blower in its air channel, cause unit interval inner blower to suck
Equilibrium point can not be reached with the air quantity discharged, cause electric efficiency low；Its movable vane wheel is formed by 8 blades are uniform, and exhaust air rate is relatively
Little, movable vane wheel is big with the local fit clearance of fan housing interface, and when motor runs, the air-flow sub-fraction that blower fan sucks in can enter
Gap between movable vane wheel and fan housing, can rebound formation eddy current when the air-flow entering gap encounters the air-flow of movable vane wheel discharge,
Thus cause airstream vibration, produce noise, and fraction flows into fan section by gap and causes idle work, affects vacuum
And efficiency.
To sum up, if needing to meet on market the requirement to high-efficiency motor, efficiency exceedes conventional D type motor of dust collector
If efficiency 35%, the cost spent will increase by 20%～30% on original Motor Foundation, and the market competitiveness is less.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is explained in detail.
A kind of efficient D type vacuum cleaner motor as shown in Figure 6, including rotor core 1, stator core 2, movable vane wheel 4,
Determining impeller 3 and fan housing 5, in described rotor core 1 and coiling on stator core 2, described rotor core 1 includes mandrel
11, on described mandrel 11 surface, protruding some external parts 12 in " T " font are used for spacing coiling as shown in Figure 1
Group, described external part 12 is uniformly distributed and is positioned at mandrel 11 in the radial direction, two adjacent described external parts 12 it
Between be winding slot 13, the size of winding slot 13 and the density of coiling directly determine the efficiency of motor heat dissipation and electric energy
Utilization rate, described external part 12 is 12, and the described angle between the contour line of winding slot 13 both sides is 30 °, described axle
The external diameter of core 11 is 18.5mm, and the external diameter of described rotor core 1 is 34.1mm, and the width of described external part 12 is 2.4mm.
The change of said structure, directly by the copper factor of coiling than front have dropped 30%, it is possible to increase the utilization rate of electric energy, reducing and damaging
Consumption.Winding slot 13 bottom land is curved, and its angle is 64 °, a diameter of 3.2mm of its arc, at the T of the external part 12 of " T " font
Prefix root is fillet, it is possible to preferably protection coiling will not scratch.
Stator core 2 is on the basis of original as shown in Figure 2, makes an adjustment the arc 21 on its four angles, Jiang Qijiao
Degree diminishes, and becomes 16 °, and the radius of its arc 21 is 35mm.The benefit so made essentially consists in, and angle formed by arc 21 becomes

The air of suction is discharged by wheel 4 by determining impeller 3, in order to ensure its efficiency, therefore needs the air capacity sucking with discharging equal, so
And existing technology, the discharge capacity of air is less than the suction volume of air, the most in use, can in blower fan residual air row
Do not go out, thus affect the suction volume of air, and then affect electric efficiency；This utility model is by the blade 31 determining impeller 3
And the change design of the blade 41 of movable vane wheel 4, the discharge capacity determining impeller 3 air is taken turns the suction volume of 4 air, thus is protected more than movable vane
Demonstrate,prove air to be detained in blower fan, therefore ensure that the balance sucking with discharging, thus reduced loss, improve the effect of motor
Rate.
Fan housing 5 air inlet forms an annular groove 51 as shown in Figure 5, adds silica gel in described annular groove 51,
The upper port of described movable vane wheel 4 embeds in silica gel, and the depth design of annular groove 51 is 4mm, and the silica gel degree of depth of filling is also
4mm, embeds silica gel for convenience, and the height of fan housing 5 is designed as 38mm, and its 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, improve the sealing between movable vane wheel 4 and fan housing 5,
Eddy current will not be formed, decrease loss, effectively improve vacuum, increase suction, improve the efficiency of motor of dust collector.And
Use silicone filler determined by its chemical composition and physical arrangement, its have nontoxic, the moisture absorption is antirust, cohesive force
By force, high temperature resistant (1500 DEG C～1600 DEG C), stable chemical performance, there is the features such as stronger mechanical strength.
In sum, by rotor core 1, the Curve guide impeller of stator core 2 structure, copper factor being have dropped 30%, with
Motor housing space becomes big, convenient heat radiation, improves the utilization rate of the energy；By the movable vane determined after impeller 3 and improvement after improvement
The combination of wheel 4, when motor runs, the air quantity that unit interval inner blower sucks and discharges reaches balance, does not haves air stagnant
Stay phenomenon；Fan housing 5 after improvement, almost without gap between fan housing 5 and movable vane wheel 4, improves between movable vane wheel 4 and fan housing 5
Sealing, decrease loss, effectively improve vacuum, increase suction；By above-mentioned to motor internal building block
Improvement, its efficiency brings up to 44%～45% from original 33%～35%.
It is emphasized that: be the most only preferred embodiment of the present utility model, not this utility model appointed
