Motor supply electric cable for variable frequency drives LAPP CANADA
VFD is the acronym for Variable Frequency Drive, which has become a very popular method to adjust a motors speed. Frequency can be defined as an electrical term meaning power pulses of voltage and current. In the United States 60 Hertz, or 60-power pulse cycles per second, are conducted through most wires and cables throughout the country. As the power in the United States is alternating current (AC) each of these frequency cycles contain one positive and one negative power pulse of voltage and current. Increasing the number of power pulses per second will make the motor turn faster. Likewise, decreasing the number of power pulses per second will make the motor turn slower. Therefore by increasing and decreasing the frequency of the power pulses, the drive can adjust the speed of the motor.
