What is a Variable Frequency Drive vfdsInduction Motor Basics Single Phase and Three Phase

All AC Variable Frequency Drives are designed to control 3 phase motors but not all of them will accept single phase power input The output of the drive is not exactly a true 3 phase AC power it is a DC generated square wave simulated 3 phase powerThree Phase Induction Motor These motors are self starting and use no capacitor start winding centrifugal switch or other starting device Three phase AC induction motors are widely used in industrial and commercial applications These are of two types squirrel cage and slip ring motors
