Working principle of brushless DC blower

DC brushless blower, as the name suggests, is an electronic device that blows air without the use of brushes. It has an efficient working principle that makes it a sought-after device for various applications. In this article, we’ll be exploring the working principle of a DC brushless blower.

The DC brushless blower consists of a rotor and stator. The rotor is a permanent magnet that rotates inside the stator. The stator is made up of copper winding, and when electricity flows through the winding, it generates a magnetic field. The magnetic field created by the stator interacts with the rotor’s magnetic field, causing the rotor to rotate.

The speed at which the rotor rotates depends on the electric current that flows through the winding. The higher the current through the winding, the faster the rotor rotates. The stator’s winding is controlled by an electronic circuit known as the drive circuit, which regulates the current flow into the winding.

Since the DC brushless blower lacks brushes, it is more efficient and less prone to wear and tear. It is also more energy-efficient than traditional blowers, resulting in less energy consumption and lower operating costs. Additionally, the DC brushless blower is more silent than traditional blowers because it operates at a lower RPM.

The DC brushless blower has numerous applications across various industries. It can be used in ventilation systems, refrigeration units, and industrial equipment, among others. It is also ideal for use in medical equipment because of its low noise levels.

In conclusion, the DC brushless blower has a simple yet efficient operating principle that makes it one of the most sought-after devices in different industries. It is more efficient, energy-efficient, and less noisy than traditional blowers – an impressive feat that guarantees its applications in numerous industries.
