What factors determine the speed of the AC fan?

When the AC fan rotates abnormally, there may be many effects. If the AC fan stops turning, first check the connector for a problem. Another possible cause is that the fan speed does not reach the normal speed required by the heater. For example, voltage instability is one of these situations. The AC fan may slow down or even stop working due to insufficient power support, thus reducing the cooling effect. Try to adjust the voltage supplied to the fan so that the fan speed can meet the corresponding radiator power requirements. This not only solves the problem of incorrect fan rotation, but also eliminates the problem of replacing a new fan.

The types of AC fans can be roughly divided into silent type and strong type. For AC fans of the same size and voltage, the noise and air volume will vary depending on the fan speed. Fan speed refers to the number of revolutions of fan blades per minute, in revolutions per minute. The rotation speed of the cooling fan is determined by the number of rotations of coils in the motor, working voltage, number, inclination, height, fan blade diameter and fan bearing arrangement. When the structure of the fan is fixed, the speed of the fan will change with the change of the working voltage. Fan speed can be measured with a special infrared speedometer.
