Tiny Cooling Fan internal coils

"Tiny Cooling Fan" (single-phase) The internal structure is composed of two coil windings, one start winding, a running winding, two windings are connected in series, thus forming the three points, the series points common Start winding end run to start end of winding end run end "Tiny Cooling Fan" to distinguish DC motor with AC motor is that the motor has three windings tributaries were wound on the rotor, the spindle is equipped with a permanent magnet blocks around live rotor, and not start capacitors, but requires brush, change the way "Tiny Cooling Fan" steering is as simple as a change in the power of positive and negative input can be achieved!
