WebThey are used to power and control the motors of pumps, fans and other engineering equipment. Therefore, a single-phase supply VFD is investigated in this study. ... WebA DC motor’s speed is proportional to the supplied voltage. If the voltage drops too far, the motor won’t get enough power to turn, but within a certain range, usually 50% of the rated voltage, the motor will run at varying speeds. The most effective way to adjust the speed is by using pulsewidth modulation.
