This white paper from Yaskawa addresses five common misconceptions about variable frequency drives (VFDs), and helps make sure you understand proper VFD usage. The five misconceptions discussed in detail include the following:
- The output of a VFD is sinusoidal
- All VFDs are the same
- VFDs cure your power factor issues
- You can run a motor at any speed with a VFD
- A VFD input current should be higher than its output current
