Frequently Asked Questions
How does a Variable Frequency Drive (VFD) vary motor speed?
It uses power electronics to vary the frequency of input power supplied to control the motor speed.
What is a primary benefit of using VFDs for large electrical systems?
VFDs provide better energy efficiency, lower starting currents, and high power factors.
Is the installation process for a VFD complex?
The documentation suggests that VFD installation is as simple as connecting the power supply to the VFD.
What do harmonics relate to when discussing VFD operation?
Harmonics relate to distortions, either electronic or mechanical, and are governed by industry standards like IEEE 519.
