If you’ve ever thought about what controls the speed of an AC, here’s your answer: Variable Frequency Drives, or VFDs. Keep reading to learn more about how VFDs work.
VFDs are a type of motor starter. Due to it being a motor starter, “VFDs convert constant frequency and voltage input power to an adjustable frequency and voltage source,” according to WEG Electric Corp. It’s with this conversion that VFDs control the speed of applications.
MCG has five different lines of VFDs available:
C100: used in applications up to 10 horsepower
M100: used in single-phase input applications
S100: used in applications demanding up to 200% starting torque at 0.5Hz
H100: used in applications from 0.5 horsepower up to 800 horsepower
SP100: built around the H100 line, it has a built-in bypass and takes up less space
