The biggest reason why ordinary motors cannot be used as variable frequency motors is that when the motor runs at a low frequency, the speed is relatively slow, the ordinary motor tail fan and the motor rotor use a concentric shaft, the motor speed is slow, and the fan blade speed is also slow, the wind is small, and is not conducive to the heat dissipation of the motor.

       Variable frequency motor is a motor specially designed for frequency converter,Variable frequency motorThe tail has a special cooler, connected to a separate power supply. When the inverter starts, the chiller at the tail of the inverter is energized, no matter how much the output frequency of the inverter is, it will not affect the speed of the chiller, and the normal operation of the chiller is conducive to the heat dissipation of the motor.

       In reality, for the torque is not very large load, such as the assembly line, conveyor belt, etc., the motor power is not very large, the frequency conversion is still used under the sonic motor, although the frequency conversion motor is not used, but the failure rate is still very small, the probability of burning the motor is even less, indicating that the insulation strength of the sonic motor can absolutely withstand the carrier frequency of the inverter.

       The cost of ordinary motors is lower than that of variable frequency motors, and low-power motors can be replaced by ordinary motors. High power is recommended to use inverter motor heat dissipation.
