Professional manufacturing and production of radiator cooling fans, condenser fans and fan motors, etc.

【 Ac fan manufacturer 】 Ac fan base

Ac dc and ac fan fan fan manufacturers difference: ac fan fan ac power supply for communication, power supply voltage will be positive and negative alternating, unlike dc fan power supply voltage is fixed, xu will depend on the circuit control, make two sets of coil turns work can produce different magnetic field. Due to the power frequency fixed exchange fan, silicon steel sheet produced by pole change speed, decided by the power frequency, the higher the frequency of magnetic switch, the faster speed will be faster in theory, like the more the more the number of dc fan speed fast principle. Frequency, however, cannot too fast, too fast will cause problems start.

Why is the 3007 silent fan difficult to achieve, is there any good way?
The 3007 fan is a 30*30*7mm fan.
Why is the radiator fan that is exhausted to dissipate more easily than the blower
Recently, we dealt with a case of changing the installation method of the cooling fan, which has a great impact on the cooling fan.
The indispensable role of medical equipment-cooling fan

During normal use of any electronic product, due to the effect of current, there will be varying degrees of temperature rise inside the device, and when the temperature rise of the device exceeds a certain range, its life will be attenuated to varying degrees (for a long time, The safety of equipment operation will also be reduced).

Will the 12V cooling fan be damaged if the voltage is lower than the rated voltage?
The commonly used cooling fan voltage is generally 12V, but some customers' products, such as temperature-controlled cooling fans, set a lower voltage for the cooling fan at low temperatures.
What is the operating voltage range of the 12V DC cooling fan?
When we choose a cooling fan, especially for certain voltages that are not very stable or have several different voltage gears for speed adjustment, we need to understand the voltage range of the cooling fan, such as a cooling fan that works with a 12V DC voltage.
