A brushless DC Axial fan uses brushless DC motors (BLDC motor) that have a cross pattern arrangement of four permanent magnets mounted on the sides of the rotor. Unlike brushed DC motors, BLDC motors do not require any commutator or brushes to operate.
The brushless DC Axial fan is a combination of a powerful BLDC motor, shaft, and fan blades. These fans are durable, reliable, and highly energy efficient. They do not produce sparks in the circuit and operate noiselessly.
The initial torque produced in DC motors is quite high, and hence, brushless DC Axial fans reach their full potential in no time. Their speed can be controlled merely by increasing or decreasing the voltage input.
To understand the cooling behavior of a brushless DC fan, you first need to understand the working of its components. However, you can understand the general behavior of the fan by closely following the voltage drops and rises in the power supply. DC Brushless Axial fans have three voltage variants: 12V, 24V .
Let us try to understand this through a simple example. If a brushless DC brushless Axial fan operates on 12 volts of voltage, then the fan would have an RPM (revolutions per minute) of around 2500. Suppose the voltage now drops to 9 volts, then the RPM of the fan would be reduced to about 1300. Such factors are taken into serious consideration during the testing and R&D of the product to minimize this possibility, that is decreased RPM with less voltage. An efficient DC brushless Axial fan is quite stable and works well even during power fluctuations.
In an environment where air flow is not easily generated naturally, air movement by external force is needed for cooling propose. Nowadays, the air movement is commonly generated by cooling fans which can be differ widely by shapes, sizes, functions etc.. Therefore, Cooling fans have typically classified into 4 categories which include Axial Fans, Centrifugal Fans, Centrifugal blowers, Cross Flow Fans.
Sunlight Brushless Axial fans are the result of more than 10 years engineering experience. Sunlight uses advanced modeling software and computer-assisted simulation systems to develop electric motors and blades that optimize a fan’s ability to pull air cleanly through the radiator core.
While many cooling fans are pieced together from many different vendors, Sunlight controls all aspects of its engineering and manufacturing processes from the design and tooling of injection molds to the winding of each electric motor at its ISO 9001 and TS16949-certified facilities.
