Description

Technical field [0001] The invention relates to a blowing and heating control module, in particular to a blowing and heating control module with high efficiency ratio, low energy consumption and low noise. technical background [0002] At present, most household appliances used in air heating and vacuuming on the market are driven by AC motors. The advantage of this is that the technology is mature, the product supply chain is mature, and the processing cost is low, but the disadvantages are poor efficiency, high energy consumption, and high noise. A project developed to use DC motors to drive the aforementioned household appliances can increase efficiency by 85%. [0003] Permanent magnet brushless DC motor is a new type of mechatronics product that has emerged with the development of semiconductor electronic technology. It is a combination of modern electronic technology (including power electronics, microelectronics technology), control theory and motor technology. Permanent ma...
