A theory that the induction motor would produce harmonic under the variable-frequency power is studied in this paper. Furthermore, the influence of the harmonic on the motor operating performance is also analysed. Then the simulation model of the variable frequency speed control is established. The simulation result shows that there is evident pulsation in the current and the torque of the induction motor under the drive of the converter.
