"Mini Air Cooling Fan" has two connectors, one end connected to the end of the winding start, one end connected to the end of the run winding triangle formation, power (no need to distinguish FireWire zero line) connected winding end of a run (ie, one end of the capacitor also together), and the other end connected to the common ground wire is connected to the motor housing; the usual single-phase "Mini Air Cooling Fan" AC motor start winding can also run as winding. If you run with the start winding winding reversed words (that is, one end connected to the common terminal of the constant power supply, then reconnected to start running side end, is to use this as a running start winding winding up), the motor will have a reversal, and this is The only way to achieve a single-phase "Mini Air Cooling Fan" AC motor rotation changes.
