Magnetic synchronizationEnergy saving fanThe energy-saving effect is achieved through permanent magnet synchronization. The permanent magnet synchronous fan developed by our company can save at least 30% energy compared to ordinary fans, greatly improving the working efficiency of the fan and saving customers a lot of electricity costs. Its characteristics mainly include the following:

(1) PMSM itself has high power efficiency and high power factor;

(2) PMSM generates less heat, so the motor cooling system has a simple structure, small volume, and low noise;

(3) The system adopts a fully enclosed structure, with no transmission gear wear, no transmission gear noise, no lubricating oil, and no maintenance;

(4) PMSM allows for a large overload current, significantly improving reliability;

(5) The entire transmission system is lightweight, and the unsprung weight is also lighter than traditional wheel axle transmission, with a higher power per unit weight;

(6) Due to the absence of a gearbox, the steering system can be designed freely, such as flexible bogies and single axle bogies, greatly improving performance.
