A method of high frequency current processing was proposed for inductance parameters identification. The d-axis and q-axis inductance parameters were identified. The effect of inverters nonlinear factors on identification accuracy of inductance parameters was analyzed and deduced. The base current and other high frequency clutter current were excluding by applying two delay filters and two synchronous axis filters on response current. The positive and negative phase’s amplitude were obtained. The d-axis and q-axis inductance were identified. The proposed method could identify inductance in the stationary state and operating state of the motor. The results showed that under the different loads and speeds of motor, the accuracy of inductance identification was high. It could give a help for improving the real driving control system. 
