Is the motor in the inverter air conditioner a direct current motor?
Inverter motor with "special AC variable frequency induction motor + inverter", the degree of automation and high production efficiency of equipment miniaturization, increase comfort, is currently replacing the traditional mechanical control and DC speed control scheme.
The motor in the inverter air conditioner is certainly an AC motor because it is powered by frequency conversion.The so-called frequency conversion refers to the purpose of regulating speed by regulating the frequency of power supply.Since the frequency is adjustable, it indicates that the direction of the current varies periodically.Some series of AC motors can also be used as DC motors, but they are not normally used in air conditioners.
Frequency conversion only for AC motors.The DC motor controls its voltage and changes its speed. Frequency independent. In one case, the frequency of direct current is 0. Therefore, the use of frequency conversion is simply can not control the DC motor.AC motors can vary the speed by changing their frequency, but they can not be controlled by changing the voltage. There is only one result of changing the voltage, and the motor must be destroyed.
