Basic Motion Control - A Glossary of Terms Used With Variable Frequency Drives and Electric Motors
Electronic VFDs are speed control devices which vary the voltage and frequency to an induction motor using a technique called Pulse Width Modulation (PWM). Since they are inexpensive and reliable, VFD's have become the preferred way to achieve variable speed operation. The following is a glossary of commonly used terms when describing or specifying Variable Frequency Drives for electric motors.
Alternating Current (AC): A periodic flow of electricity which changes direction each cycle, reaching a maximum in one direction, decreasing to null, then reversing to reach a maximum in the opposite direction.
