It has advantages of small size, lightweight, high torque density, high efficiency and power factor, good moisture-proof performance, low noise, low vibration, easy for installation, maintenance-free, high-cost performance and etc.
For self-generating enterprises, variable frequency speed regulation can give full play to its advantages. According to the characteristics of the motor frequency converter (the variable frequency air compressor works in energy saving under the rated voltage), it has an obvious effect on the places with the low grid voltage.
