    Tips: Variable frequency speed control of AC Induction Motor
    According to the speed formula of induction motor, it can be seen that when the slip s remains constant, the motor speed nis basically proportional to the power frequency f. Therefore, changing the frequency f can regulate the speed of induction motor smoothly. Changing the frequency of power supply is a economical speed regulation method, and it is also one of most popular ways of induction motor speed control.
    Variable frequency speed control is a way to change the power frequency of motor stator and then change its synchronous speed. The main equipment of variable frequency speed control system is frequency converter or variable frequency drive (VFD) that provides frequency conversion for the power supply. The variable frequency drives can be divided into two categories: AC-DC-AC VFDs and AC-AC VFDs.
