Phase AC Motor – Speed ​​Regulation of Asynchronous Motors
Speed ​​regulation of asynchronous motor: In theory, the asynchronous motor can control the frequency and voltage of the AC power, or the resistance of the rotor and the distribution of the magnetic poles of the motor. Because the range of voltage regulation and speed regulation is not large, it can only be used in occasions where the speed regulation requirements are not high, and the application is not widespread. Frequency conversion speed regulation: When it comes to frequency conversion, everyone may have heard of it. The full name of variable frequency speed regulation is variable voltage variable frequency speed regulation (VVVF), which means that the voltage is changed when the frequency is changed, so that the speed regulation range of the asynchronous motor is large enough.
