The output voltage and current of frequency inverter includes a lot of higher harmonic when the frequency converter provides power for three-phase asynchronous motor. This will lead to the increase of asynchronous motor loss, temperature rise and causes series bad influence of vibration and noises. So discusses the influence of frequency inverter on three-phase asynchronous motor, especially significant for studying the efficiency of asynchronous motor and energy saving. At the same time it has important reference value for studying new frequency motor.
