| Abstract: | The starting stator current signal is abstract ed high-speedy by the system of data collection card and PC and frequency of the f irst gear resonance wave is abstracted from it. And analysing the changing regul arity of the first gear resonance wave based on excellent time-frequency locati on of wavelet package transform,the starting torque and speed characteristic is abtained indirectly,and a new method of the measurement of induction motor st arting characteristic is put forward. |
