as we know that N=120f/P
speed of an im can be controled only through changing no if
poles, can we control by changing the frequncy????
Answer Posted / naveen
Yes we can able to change the frequency of the supply by using of the cyclo converter and PWM inverter these power electronics circuits used to change the frequency and we achieve the variable freq and vary the speed of the IM
