Abstract: Now the popular asynchronous motor velocity modulation method may divide into two kinds: The frequency conversion velocity modulation and the live pressure velocity modulation, in which asynchronous motor frequency conversion velocity modulation application are many, its velocity modulation method may divide into two kinds: The frequency conversion live pressure velocity modulation and the vector control method, the former control method is relatively simple, some more than 20 year development experience.Therefore application quite many, at present in the market sells the frequency changer most all uses this control method.
Key words: Asynchronous motor; live pressure velocity modulation;frequency conversion live pressure
