Description

Technical Field

[0002] Variable Frequency Drive (VFD), also known as variable frequency speed regulator, is an electrical device used to adjust the speed and torque of AC motors. It adjusts the speed of the motor by changing the frequency and voltage of the power supply to the motor. VFDs are widely used in industrial, commercial and household fields. They can improve the operating efficiency of equipment, save energy and reduce consumption, and also reduce wear and tear on equipment and extend the service life of equipment. External VFDs will generate a lot of heat during operation. This is because the electronic components inside the VFD (such as transistors, rectifiers, inverters, etc.) will lose energy during the current conversion process, resulting in heat generation. Especially in the case of high power and long-term operation, heat will accumulate and affect the performance and stability of the equipment.
