The highest, conventional vacuum cleaner electric fan generally uses brush motor, its rotating speed generally
Between 20000-40000, although its rotating speed can meet the requirement of vacuum cleaner electric fan, but there is brush electricity
The commutator wear of machine is fast, and the life-span is short, and noise is big, and performance is low.
Along with the raising of the energy consumption standard of vacuum cleaner industry, and consumer is small-sized to portable dust collector
How the demand changed, make vacuum cleaner electric fan to meet volume little, can improve again efficiency time quiet
A big technical barrier for industry.Brshless DC motor is brush-commutated owing to eliminating relative to brush motor
Using electronic commutation, rotating speed can reach more than 60,000, and the life-span reaches more than 2000 hours.There is no carbon
The friction of brush, it is lower that noise can drop.
The rotating speed of brushless electric machine is high, requires that semiconductor power switch pipe break-make frequency is the highest accordingly,
Therefore, generate heat more serious.
At present, on market, motor of dust collector is using the two poles of the earth permanent magnetic brushless as structure first, and it can
To reduce the device for power switching switching frequency of electric machine controller, reduce the heating of power tube, significantly
Improve effective through-put power of power tube.But, this kind of existing motor is monophase machine, i.e. motor
Only one phase energising, the power density of motor is less, and motor torque fluctuation and noise are big.
The two poles of the earth single-phase radial flux brush-less permanent magnetic that existing vacuum cleaner brushless permanent high-speed motor is traditional
Motor, the axial length of motor to reach certain length could export certain power, usual motor
Axial length dimension be far longer than the radial dimension of motor.The length so causing blower fan is long,
Some axial dimensions are required comparatively short mounting structure, and radial dimension of power of motor is due to axial chi
Very little restriction, it is bigger that usual power can not do.
Accordingly, it would be desirable to work out a kind of novel dust collector motor, solve the two poles of the earth on existing market
Single-phase permanent brushless motor exist power density is less, motor torque fluctuation is big, noise and volume
The biggest problem.

According to Arnold constant formula, D^2*L* (n/P)=C understands, punching diameter D and rotating speed
N mono-timing, core length L is proportional with power P.When needs increase power P, accordingly
Core length L increase the most accordingly, therefore, the length easily causing blower fan is long.To some axles
To the mounting structure that dimensional requirement is comparatively short, radial dimension of power of motor due to the restriction of axial dimension,
What generally power can not do is bigger.Can obtain according to the deformation of Arnold constant formula again:
