VVVF Speed Control of Induction Motor
VVVF stands for Variable Voltage Variable Frequency. VVVF Speed Control method is widely used method for Induction Motor. Origin of VVVF Speed Control As we know that synchronous speed of machine is given as N (rpm) = 120f/P …………………………………(1) where f is frequency and P is number of pole. Thus if we can change the … Read more
