Tiny Cooling Fan internal structure and composition analysis

"Tiny Cooling Fan" also need a starting capacitor, usually a capacity of between 1-2uf, pressure is usually 250v, which refers to the mains AC motor normal use, such a capacitor is polyester capacitors, no positive and negative points There are two connectors, one connected to the winding start ends, one end connected to the end of the winding operation, the formation of triangle, "Tiny Cooling Fan" power supply (no need to distinguish FireWire zero line) run one after winding end (ie, one end of the capacitor also together), and the other end connected to the common grounding line to pick up the motor housing; usually start winding single-phase AC motor can also be run as winding, if you run winding start winding swap with words (that is, one end connected to the common terminal of the power supply constant, then reconnected to start running side end, so that by the start winding as the running winding up), "Tiny Cooling Fan" will have reversed, and this is the only way to change the single-phase AC motor rotation to achieve!
