Variable frequency motorThe main cooling fan is generally driven by an independent motor, which belongs to forced ventilation cooling380V,50HZPower frequency power supply is used independently. Today, Senli Motor Xiaobian will take you to understand about itVariable frequency motorThe cooling fan.
Generally, the star connection method is used, which is the same as the wiring method of the ordinary motor, and there is no difference, but it can not be connected with the motor in order. The cooling fan of the inverter motor should be connected to the power frequency power supply, and the control line of a frequency converter should be connected, so that the cooling fan will also rotate when the motor starts.
If the cooling fan and the motor are in parallel, then if it is not running at the rated frequency, the speed of the fan is proportional to the frequency, it can be said that the speed is basically the same; This will cause a low frequency situation, frequency conversion motor cooling fan for low speed operation, insufficient air volume, this is no way to ventilation and heat dissipation, which is commonThree-phase asynchronous motorMounting directly on the motor shaft makes no difference.
As a key component of the variable frequency motor, the reliability of the cooling fan is particularly important in quality, which has a greater impact on the operation of the equipment, and will directly affect the work and service life of the equipment.
