vfd cable length reflected wave It takes into account the voltage overshoots that occur on top of each pulse of the basic PWM waveform
As cable lengths grow so does the magnitude of reflected voltage Reflected wave and standing waves Possibility of motor bearing failures Limited motor cable length These complications are significantly reduced in severity when proper VFD cable is

Voltage wave reflection is a function of the voltage rise time dV dt and the length of the motor cables Impedance mismatches cause voltage pulses to be reflected back in the direction from which they arrive As these reflected Variable frequency drives VFDs and motors can reduce carbon emissions and increase efficiency reliability and safety across various systems
This post looks at motor cable lengths and how to get the longest length possible The results of the shielding effectiveness testing are documented in Figure 3 As demonstrated by the pale green blue trace in Figure 3 foil shields are simply not robust enough to capture the
