DC fan motor is a kind of motor that works by direct current, and its principle is to convert electric energy into magnetic energy through direct current and electromagnetic induction, and then the magnetic energy is converted into mechanical energy to make the fan blades rotate, so as to realize the conversion of direct current energy to mechanical energy. DC fan motors are mainly composed of four parts: rotor, stator, motor, and outer frame, of which the stator and rotor are its core components.

The advantages of DC fan motors include:

1. high efficiency and energy saving: DC fan motors have low loss, high efficiency and high power factor, so they can save energy and reduce energy consumption during use.

2. Low noise: DC fan motors run at low speeds and have low noise, which does not affect the surrounding environment too much.

3. Good speed regulation performance: DC fan motor has good speed regulation performance, which can be adjusted according to the need to meet different needs.

4. Long service life: DC fan motors have a long service life, generally up to several years or even longer.

5. Wide range of applications: DC fan motors are widely used in a variety of fan devices, such as floor fans, USB small fans, handheld small fans and bladeless fans.

Overall, DC fan motors have the advantages of high energy efficiency, low noise, good speed regulation, long service life and wide application, etc. It is a very practical type of motor.
