Application of Variable Frequency Speed Regulation Technology in Fan System

With regard to the problem in fan air volume control, the research on air volume method was carried out, and the air volume control method for frequency conversion speed regulation was adopted. In this regard, a motor variable frequency speed regulation system was designed, and a variable frequency control software was developed. In order to verify the control effect of the system on the fan air volume, a measurement experiment on the fan speed was carried out, and it was concluded that the variable frequency speed regulation method was highly precised, and had a sound linearity. While finally, this variable frequency speed regulation system was applied in the fan system, and the equal thickness collection experiment on the material was carried out in order to ensure the strict control over the air volume, which has obtained a relatively sound application effect.
