Troubleshooting VFDs with Low Pass Filter

Application Notes

Today, three-phase induction motors are the most important workhorses in industry and commercial facilities. An AC induction motor is commonly used as a constant-speed drive when fed from a voltage source of fixed frequency. Unfortunately, running a motor at maximum speed, regardless of the varying demands of production, means a great deal of electric power is wasted. In many motor applications, energy use can be reduced considerably if the speed of the motor varies in response to the changing process conditions. With the advent of solid state electronics, variable speed drives can regulate the speed of a three-phase AC electric motor by converting three-phase AC line voltage to a quasi-sinusoidal pulse width modulated (PWM) waveform in which the frequency and voltage level can be varied.
