FAQ

1. Why use an axial fan for variable frequency motors?
   
   The ordinary motor is powered by constant frequency and constant voltage, the speed is constant, and the ventilation and heat dissipation are in a thermally stable state. The variable frequency motor is specially designed for the operating conditions of variable frequency and variable voltage. On the one hand, the current is non-sinusoidal, and the harmonic components generated by the inverter lead to an increase in the copper loss of the stator and rotor of the motor; The proportion of the loss of the motor increases, but the cooling air volume decreases in the proportion of the cube of the rotation speed, which makes the cooling condition of the motor worsen at low speed and the temperature rise sharply rises. Therefore, the cooling effect of the self-contained fan of the variable frequency motor is far from meeting the heat dissipation requirements of the motor, and forced independent ventilation must be used, that is, an independent fan.
   
   When the frequency conversion motor is used, the principle of starting the inverter and the motor is to start the axial flow fan before turning on the power of the motor to ensure the cooling requirements of the motor; When the axial flow fan does not turn on the motor and the motor runs independently, the motor burns due to heat, which is also a problem that often occurs in the use of some low-end users.
   
   Another problem is that if the axial fan and the motor share the same power supply, when the motor is used by frequency conversion, the motor of the axial fan is also used by frequency conversion, and the motor supporting the fan will suffer the same fate of damage, which will not cool the main motor. At the same time as the effect, the fan itself cannot avoid bad luck.
