A variable-frequency control system is a type of system that regulates the operating speed of motors or other equipment by adjusting the frequency of the power supply. At its core is the variable-frequency drive (VFD), which can convert a fixed-frequency power supply into an AC power supply with a variable frequency, thereby enabling precise control of the equipment. The heat generated during operation is primarily dissipated through air flow; this system employs forced-air cooling for heat dissipation. It features a compact structure, stable operation, and comprehensive functionality.
