Applications:
Variable-frequency drives (VFDs) control the speed and torque of AC motors by varying the frequency of the voltage to the motor, which is possible to limit the effect of high frequencies on the surrounding equipment and possibly prevent costly machine downtime.
Where there is a risk of mechanical damage, armored cables should be used.
