The electronic fan is developed based on the control technology platform of permanent magnet DC BLDCM and Holzer free motor. It adopt international advanced “PWM” frequency conversion control technology, closed-loop system design. ECU reads radiator inlet and outlet water, intercooler temperature signal. According to the heat dissipation characteristic curve of the engine and the characteristic curve of the supercharger, and according to the “fuzzy” control mechanism of the temperature variation trend, the start, stop and speed of the fan are directly controlled. to maintain the engine requirements of the best water, air temperature degree. The design of the product meet the requirements of ISO, IEC, QC and other relevant standards. its energy consumption can be reduced to 30%, and the application in the field of bus can achieve about 8% oil saving ,8 dB noise reduction (a), emission reduction, increase the effective power of the engine, prolong the engine life, and avoid maintenance.
