I see that lower voltage means not so good performance.
My confusion is, if that is the case, why constant v-f is so popular. I will make my confusion clearer.
For V-f, inverter is used to generate three phases. Inverter is fed by DC bus voltage which itself is rectified from supply voltage...
I have got an 1HP induction motor rated at 230V(line), 60Hz. If I run it at 185V(line) at 65Hz, what factors are affected in its performance?
I am hoping for your expert advices..
