RL circuit is taken into consideration, in which the transient current signal includes a period component varying in sinusoidal waveform and a non-period component varying in exponential waveform.
The motor drive system almost all use inverter supply power, which output non-sinusoidal voltage-current and produce non-sinusoidal electromagnetic field.
