    EC fan speed axial cooling fan performance is still very important. General customers in the purchase of EC fan will be referred to how much speed, then how much speed will give fans what is the impact?

    EC fan speed is the number of fan blades per minute rotation, the unit is rpm. The fan speed is determined by the number of turns in the motor coil, operating voltage, number of fan blades, pitch angle, height, diameter, and bearing system. Fan speed and fan fan page quality is not necessarily related. Fan speed can be measured by the internal speed signal, or measured externally.

    Sometimes customers need different speed of the EC fan to meet different needs. For example: the use of environmental temperature, pressure, humidity and so on. So we design according to customer needs adjustable fan speed EC cooling fan.

    EC fan comes with a temperature sensor that can automatically control the fan speed based on the current operating temperature, high temperature increases the speed, low temperature is reduced speed, in order to achieve a dynamic balance, so as to keep the wind noise and heat dissipation A best combination of points, but also to achieve energy saving, saving customers unnecessary waste of resources.

    In addition, when the structure of the EC fan is fixed, the rotating speed of the DC fan (that is, the fan using the DC power) changes synchronously with the change of the operating voltage. The speed of the fan can be measured by the internal speed signal, or externally. Fan speed and cooling capacity is not directly related to the air flow is the fundamental factor in determining the ability to heat, higher fan speed will bring higher noise, optional radiator products if the air volume is about the same, you can choose a low speed fan, Will be quiet when in use.

    Therefore, the fan speed and cooling fan quality is not necessarily linked. Fan speed will be determined by the number of turns in the motor coil, operating voltage, number of fan blades, pitch, height, diameter and bearing system.
