Cooling Fan - Brushless DC Motor
Jan 05 , 2022
Motors that power ventilation cooling fans are usually divided into brushless motors or induction motors. Brushless motors are sometimes called electronically commutated motors. Commutation refers to the act of switching the electrical connection from one motor winding to the next one. Motor windings in the DC cooling fan motor is generally located in the stator or stationary portion of the ...

Cooling Fan - AC Shaded Pole Induction Motor
Jan 05 , 2022
In addition to the DC brushless motor, there is another type of shaded pole induction motor in the exhaust cooling fan. As the name suggests, Induction motors is because electromagnets in the stator induce magnetism in the rotor. They induce magnetism in the rotor because, unlike the rotor in a brushless DC motor, the rotor in an induction motor contains no magnets. A separate small winding is use...

How to design dust-proof cooling fans?
Jan 11 , 2022
The characteristics of the cooling fan itself are different from other products. Brushless cooling fan actively stirs the air and accelerates the airflow, so it also sucks in dust. There are two main aspects of inhaling dust. One is sucked into the bearing and the other is sucked into the rotor and stator. Inhalation of dust more or less affects the cooling fan, causing the fan to slow down and ev...

If the positive and negative poles are reversed, will the cooling fan burn out?
Jan 18 , 2022
DC cooling fan has two positive and negative power lines. When installing the cooling fan, if the positive and negative lines are connected reversely by wrong operation, will the cooling fan burn out? Whether the axial cooling fan is burnt out or not is mainly related to the IC Design of the cooling fan. In general, the drive IC with double wire winding method has internal protection design. If th...

How to choose the cabinet cooling fan?
Jan 26 , 2022
1. When purchasing cabinet cooling fans, first confirm the size of the cabinet, select the appropriate fan model and appearance for installation, and then determine the parameters such as voltage, airflow, speed, current, noise and other parameters. 2. Cooling fan voltage, which can be divided into DC voltage 5v, 12v, 24v and 48V; AC voltage 110V, 220v, 380v. If the wrong voltage is connected, the...

What should be paid attention to when installing centrifugal fan?
Feb 16 , 2022
First of all, when connecting the centrifugal cooling fan, the foundation joint surface, and the inlet and outlet air ducts, they should be adjusted to fit naturally, not forcibly connected, and the weight of the air ducts should not be concentrated on the casing to avoid deformation of the casing and affect the normal operation. The inlet and outlet air ducts of the centrifugal fan should be conn...

Where is the cooling fan used?
Feb 23 , 2022
Cooling fans, as the name suggests, are used for ventilation and heat dissipation. It is widely used in various industries and fields, because in many electronic equipment and machinery, if there is no cooling device installed in the equipment, the working temperature may be too high, which may cause the performance of the equipment to decline, or even be damaged. For normal and efficient operatio...

Why the speed of DC cooling fan slows down?
Mar 26 , 2022
Why the speed of DC cooling fan slows down? The speed of the cooling fan is determined by voltage, fan blade angle, diameter, number of fan blades, bearings, etc. So what is the reason why the cooling fan slows down? The speed of the cooling fan is mainly determined by the structure and components of the fan itself, the bearing friction and the wind resistance of the inclination angle of the fan b...
