It is said that speed of an induction motor depends on its frequency and torque depends on current. But I will explain what i cant understand here.
Let’s think an induction motor runs with constant load and speed. When I increase its current (by varying voltage) but keeping the source frequency constant (by vfd) what happens ?
For me, when i increase current it will cause torque to increase , when torque increase and motor will start to accelerate aftet it gets high speed it will find another point source and load torque trades off each other. In this way I don’t change frequency but motor gets higher speed by increasing current.
Is this assumption correct ? Or do i miss something ?
