Our VFD Drives or Variable frequency drives are used to control the speed and torque of an AC motor by adjusting the motor’s input frequency and voltage. VFD Drives may be either electric, hydraulic, mechanical or even electronic. They control the speed at which a motor operates in a precise and constant manner. Otherwise, the machines that use these mechanisms and motors would work as per their own characteristics and power supply, which would be highly ineffective. PLC Technologies is a leading supplier of Variable Frequency Drives from 200W to 450KW.
