DC Fan line package (STATOR) and soft magnetic materials

"DC Fan" for the use of 177,277 / 266 of a fan coil generally use two-way ? coil winding and co-leads three taps (where a tap is connected by two sets of coils from end to end. Line package turns ﹑ characteristic impedance directly affect the number of fan thrust and ultimately affect the size of the speed, etc according to the actual requirements of the soft magnetic material is disposed fans, usually 3 to 8 silicon steel sheet, the stronger the magnetic permeability, the magnetic field strength of the poles of the stator 4 generated by the strong.
