Axial Flow Fan Energy Saving Transformation

When the axial flow fan is started, the motor current will be 5-6 times higher than the rated value, which will not only affect the service life of the motor but also consume more power. There will be a certain margin in the selection of the motor when the system is designed. , the speed of the motor is fixed, but in actual use, sometimes it needs to run at a lower or higher speed, so it is very necessary to carry out frequency conversion transformation. The frequency converter can realize the soft start of the motor, achieve the purpose of energy saving and speed regulation by changing the input voltage frequency of the equipment, and can provide the equipment with protection functions such as overcurrent, overvoltage, and overload.
