      220V Cooling Fan capacitor replacement

      Date: 2015-7-6   Click: 1572 Times

      "220V Cooling Fan" capacitor is used to start the motor, the pace is by the governor to control the magnitude of the current. I'm talking about the heat because you replace the small capacitance caused by the fan motor starter prolonged heat generated. It has long been an impact on the motor. We recommend that you do not change too small is the reason. Because "220V Cooling Fan" mostly single-phase and single-phase power can not be directly used to generate a magnetic field sufficient to start, can not maintain good running so that the motor windings are generally two, that is the main and auxiliary windings, directly into the primary winding circuit, the auxiliary winding after a capacitor in series with the circuit. Thus there is an angle difference between the auxiliary winding and the capacitor will act as phase shift, so that the phase of the emergence of a deviation, this is equivalent to obtaining a 2-phase, and the phase is different, you can start up the rotor, and then maintain the magnetic field allow the main winding He operated auxiliary winding to continue to promote that "220V Cooling Fan" not because of external force to stop.
