Variable frequency drives

Principle of variable frequency drives

Electric motors are indispensable on the factory floor, as they drive most of the machines that we use. Unfortunately, they’re not able to control their own speed. That’s where variable frequency drives, or VFDs come into play. By increasing or decreasing the voltage frequency applied to the motor, frequency drives can control the speed, while also maintaining safe levels of current passing through the motor.

Variable frequency drives can help in a wide range of applications such as:

  • Centrifugal pumps
  • Compressors
  • Fans
