                  If it is determined "220V Cooling Fan" vibration caused by mass imbalance, so long as the measurement point of the horizontal or vertical direction in the vicinity of the bearing housing shell vibration, use of influence coefficient method, increase in the impeller, will be able to reduce fan vibration within the desired range. "220V Cooling Fan" impedance will have two functions, one is the impedance protection, thermal protection, respectively, one is described as follows:
                  1. Impedance protection to prevent motor burnout occurs when you shut down, the way to set the impedance of the motor winding (AC resistance), so that appreciation is maintained at a temperature below the burning temperature of the motor.
                  2. The thermal protection to prevent burning mode "220V Cooling Fan" occurs when the motor is closed before the motor temperature reaches appreciation burnout temperature, cut off by the heating element
