The advantages of frameless DC fans
What are the advantages of frameless DC fans?
The rotor of the frameless DC fan includes frameless DC fan blades (as the source of airflow) and fan shaft (used to support the balance of fan blade rotation), rotor magnetic ring, permanent magnets, and the key to improving the magnetic stage switching speed is outside the magnetic ring Frame and fixed magnetic ring. In addition, it also includes a support spring, through which the nodules are fixed to rotate the entire part, the motor part, the direction of rotation, and the size of the dynamic rotation speed key. Its speed regulation performance is good, and the control is simple.
Frameless DC fan material: plastic material, if choosing ball bearing, this fan can be used continuously for more than 50,000 hours, DC internal structure transformer and main control board (including frequency conversion circuit, rectifier filter, amplifier circuit, etc.) will not be affected by voltage fluctuations, so its service life long.
1. The length of the frameless DC fan is not limited, and the force of the impeller can be arbitrarily selected according to different user needs.
2. The airflow flows through the impeller and is affected by the two forces of the blades, so the airflow can reach a long distance.
3. No turbulence, uniform wind.
4. Cost-effectiveness — Frameless DC fans produce less friction, reduce noise levels and extend their overall lifespan. They also use less power, which saves battery power in portable applications.
5. Highly versatile-frameless DC fans can work at different operating temperatures. The standard model can work anywhere from -10°C to 70°C.
Design flexibility-Our frameless DC fans have many different design options. These include protection from dust, moisture, and salt spray, as well as dual ball bearings or proprietary bearings to improve reliability, performance, and service life. Other options include tachometer and pulse width modulation speed control.
