220V Cooling Fan capacitor configuration

Capacitance as "220V Cooling Fan" an important part, may reflect the merits from the side of the motor, the home fans in general capacitance value is smaller, the motor starting current smaller, more energy-efficient, more stable relative performance of the motor; Also rated voltage value is larger, the capacitor voltage shock resistance ability is stronger, the motor performance will be relatively more stable. "220V Cooling Fan" capacitor capacity size is usually chosen multimeter R × 10, R × 100, R × 1K block tested judgment. Red, black pen, respectively, then the negative capacitor (Before each test, the capacitor discharge), from the hands of the deflection to determine "220V Cooling Fan" capacitor quality. If hands quickly swing to the right, left and then slowly returned to its original position, the capacitor is generally good. If the hands are no longer swing swing, indicating that the capacitor has a breakdown. If the gauge needles swing gradually return to a position stop bit, then "220V Cooling Fan" capacitor has leakage. If you do not put hands up, indicating that the capacitor electrolyte has dried pushed lose capacity.
