What is a small 12V DC blower?

A DC blower is a device that converts electrical energy into mechanical energy. After continuous compression of air, it can generate a large amount of wind. The small DC blower has various characteristics such as easy to use, safe operation, high-efficiency furnace, and low efficiency, so it is sought after by consumers. The main models of small DC blowers are 5V DC Blower, 12V DC Blower, 24V DC Blower. Today, I will explore the excellent performance of the 12V small DC blower.

The DC blower converts direct current into mechanical energy to drive the wind wheel to rotate. The air inlet and outlet are in the vertical wind direction, and constantly compress the air to generate a large air volume for blowing. Collectively referred to as DC blower.

What is the working principle of a DC blower?

According to Ampere’s right-hand rule, a conductor passes current and a magnetic field is generated around it. If the conductor is placed in another fixed magnetic field, it will generate attraction or repulsion, causing the object to move. Inside the fan blade of the DC fan, a rubber magnet filled with magnetism is attached. Surrounding the silicon steel sheet, the shaft is wound with two sets of coils, and the Hall induction component is used as a synchronous detection device to control a set of circuits that make the two sets of coils wound on the shaft work in turn. The silicon steel sheet produces different magnetic poles, and the magnetic poles and the rubber magnet generate repulsive force. When the repulsion force is greater than the static friction force of the DC blower, the fan blade rotates naturally. Because the Hall sensor components provide synchronization signals, the fan blades of the DC blower can continue to operate. As for the direction of rotation, it can be determined according to Fleming's right-hand rule.

What are the performance characteristics of the 12V small DC blower?

1. The DC blower uses direct current to convert it into mechanical energy to drive the wind wheel to rotate. The air inlet and outlet are in a vertical wind direction, and the air is continuously compressed to generate a large amount of air for blowing.

2. The DC blower is a fan that firstly inputs DC power to rotate the DC motor to drive the fan impeller to rotate, thereby realizing the process of converting DC power to mechanical energy. The biggest feature of the DC blower is the optional DC motor.

3. The wind blades and wind cover of the DC blower are made of the hardest ADC12 material in the world, which is equivalent to the same material of Mercedes-Benz wheel rims.

4. The bearing of the DC blower adopts high-speed, high-temperature-resistant imported bearing NSK bearing, 2800 rpm at 50Hz, 3450 rpm at 60Hz, lubrication-free, 20,000 hours of maintenance-free, equivalent to continuous operation 2 years.

5. The DC blower has two functions of air supply and suction. The DC blower adopts Siemens technology, and the passing gas is oil-free and dry. DC fans are suitable for auxiliary equipment in multiple machinery industries.

The above is a big analysis of the performance characteristics of the 12V small DC blower. I hope that it can provide suggestions for consumers who are not yet determined whether to buy it.
