Electrical Drives (VFDs/VCDs)

The 60% of the world’s generated energy are consumed in the rotating machines and more than 90% of these machines are induction machines. The induction machines consume more of the world’s generated electricity than any other piece of electrical equipment. In any type of small and large scale industry/manufacturer/plants, motors are vital in the line of production but in most cases it consumes more energy than required. The technology in Power Electronics has now quite matured itself so that to overcome the issues of conventional losses, protection and control. In this aspect the electrical gadgets i.e. Variable Frequency Drives (VFDs) or Variable Speed Drive (VSDs) and Vector Control Drives (VCDs) provides energy efficient control of electric motors in applications that include fans, pumps, industrial automation, building services and lifts/elevators. By using these electrical gadgets, it is possible to save a significant amount of electrical energy (depends on each case) without affecting the load performance.
