The three-phase induction motor driven at speed can be changed, they need to change the frequency of the light switch by using inverter. In order to change the frequency of a light switch.
The three-phase induction motor drive that can change speeds, it is necessary to change the frequency of the AC by an inverter. In order to change the frequency switching.
Three phase induction motor drive can change speed is needed to change the frequency of the power switch by the inverter. In order to be able to change the frequency of the power switch.
