Variable frequency drives, or commonly known as VFD’s, use pulse width modulation (PWD) techniques to control AC drives. If improper cabling is used in these drives, the high frequency pulses found in VFD can cause destructive motor bearing currents. The answer to these frequency pulses is many times the uses of variable frequency drive cables [...]
