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 Arnold constant fortran again:
L=(PC)/(D^2*n), it is known that, by increasing motor stator external diameter or increasing speed, can be effective
Reduce motor axial length L.Use the brushless electric machine of axial flux structure, because brushless motor speed is high,
Motor stator D outside dimension is big, can efficiently reduce motor in guaranteed output P mono-timing
Core length L.
The beneficial effects of the utility model are:
By using axial magnetic flux brushless electric machine, increase motor stator outside dimension, increase speed,
Guaranteed output P mono-timing, can efficiently reduce the core length L of motor, make the axle of motor part
To length reduction to original 1/2, the axial length of blower of cleaner system reduces 1/2.
