Now, with the rapid development of power electronics and frequencyconversion technology of adjusting speed of AC induction electromotor changes quickly and new control method appears ceaselessly. DC electromotor by the AC induction electromotor is replaced by the AC induction electromotor in wide range. The AC variable frequency speed regulation is generally acknowledged by the home and abroad that it has a great future with excellent speed regulation, high efficiency saving energy, extensive scope of application and other merit. Keywords: frequency converter。change speed
