With the development of technology, brushless fans have gradually become the new favorite in the market. Compared with traditional brushed fans, brushless fans have many unique advantages. This article will introduce the difference between brushless fans and brushed fans, and focus on the 6 advantages of brushless fans.
The difference between DC brushless fan and brushed fan
Structural Difference
First of all, there are obvious differences in structure between DC brushless fans and brushed motor fans. The rotor in a brushed motor fan has brushes attached to it, and these brushes create contacts through friction that create the current path. In brushless motor fans, brushes are not required, and the permanent magnets on the rotor are driven by an electronic controller to achieve rotor movement.
Working Principle
Secondly, the working principles of brushless fans and brushed motor fans are also different. The rotor of the brush motor fan is controlled by the brush, and the magnetic field is generated by continuously changing the direction of the current on the rotor, thereby driving the rotor to run. The brushless motor fan monitors the rotor position through an electronic controller, and precisely adjusts the current and magnetic field to keep the rotor in the correct position at all times.
Life and Reliability
In addition, DC brushless fans have obvious advantages in terms of life and reliability over brushed fans. Since there are no brushes in DC brushless fans, there is less wear and tear on their components. At the same time, the rotor of the brushless motor fan will not be rubbed by the brushes, so there will be no sparks, reducing the risk of fire. This makes the brushless fan more reliable for long-term operation and harsh environments.
Advantages of DC Brushless Fans
In addition to the difference from brushed motor fans, brushless fans have the following outstanding advantages:
High Efficiency and Energy Saving
The high efficiency of brushless motor fans is one of their biggest advantages. Compared with brushed motor fans, brushless motor fans have higher energy efficiency. Because the brushless motor fan adopts advanced control technology, it can precisely adjust the rotor movement and current, and reduce energy loss. This enables the brushless motor fan to generate greater wind power and provide better heat dissipation under the same power.
Quiet, Stable
Another advantage is the quietness and stability of DC brushless fans. Since there are no brushes in the brushless fan, the noise caused by brush friction is eliminated. At the same time, the DC brushless fan precisely adjusts the current through the electronic controller, making it run more smoothly and reducing the generation of vibration and shock.
In contrast, the brushed motor fan will produce obvious brush friction noise when it is running, which will cause certain interference to people’s living and working environment. The low-noise feature of the brushless fan makes it more suitable for places that require a quiet environment, such as bedrooms, offices, etc.
Energy Saving and Environmental Protection
The brushless motor fan has less loss in the process of electric energy conversion, which can make more effective use of electric energy and improve energy utilization. In contrast, brushed motor fans are less efficient due to issues such as brush friction and energy loss. Therefore, the brushless motor fan has significant advantages in energy saving and emission reduction, which can reduce energy consumption and reduce the impact on the environment.
Long Life
Since brushless fans do not use brushes, there is no problem of brush wear, so they have a longer service life. Due to brush wear and other reasons, the traditional brush motor fan needs to replace the brush after a period of use, which affects the life of the fan. The brushless design of the brushless motor fan prolongs its service life and reduces maintenance costs.
Precise Control
The brushless motor fan can achieve precise speed regulation and wind regulation through electronic control technology, and has better controllability. Traditional brushed motor fans usually use mechanical switches or rheostats to adjust the speed, which is not flexible enough to operate. The brushless motor fan can realize stepless speed regulation through the electronic control system, and users can choose the appropriate wind power according to their needs.
Small and Lightweight
Brushless fans can achieve a more compact and lightweight design due to the use of advanced electronic control technology and material technology. In contrast, traditional brushed motor fans are usually bulky and not portable. The compact and lightweight features of the brushless fan make it more suitable for personal use, such as outdoor camping, travel and other scenarios.
UnitedStar’s 24 Inch Electric Ceiling Fans with Solar Panel and BLDC Copper Motor
This 24 inch solar ceiling fan has a BLDC 100% copper, ball bearing motor. With the use of BLDC motor in ceiling fan can save 60% electricity. The lifespan of BLDC fan is more than a normal ceiling fan because there is no heat generated in BLDC Motor. And there are fewer chances for the winding failure due to the use of high thickness copper wire in the winding.
To sum up, brushless motor fans have many advantages over traditional brushed motor fans. There are obvious differences in their structure, working principle, life and reliability. The brushless motor fan has become a new favorite in the market due to its outstanding advantages such as high efficiency, energy saving, quietness, stability, energy saving and environmental protection, long life, precise control, and small size and light weight. With the continuous development of technology, we believe that brushless motor fans will be more widely used in the future and bring more convenience and comfort to people’s life and work.
