Thanks for the reply. I understand it better now. Basically I gather that to increase the torque of an induction motor you have to alter the v/hz ratio. Obviously there are limits but this is what vector control does also.
I have a question about the torque of an A.C. Induction motor. Would changing the v/hz ratio or running it in vector control actually give the motor more locked rotor torque than an across the line starter. I am trying to get a better understanding of the v/hz ratio effect on a motor. Thanks in...
