VARIABLE SPEED DRIVE

DESCRIPTION

1. It is estimated that electrical drives and other rotating equipment consume about 50% of the total electrical energy generated in the world today. Other estimates are that pumps, fans, blowers and compressors consume as much as 65% of this total. A large proportion of these applications are powered by fixed or constant speed drivers whose load demands often fluctuate. This poor match of speed and demand results in considerable wasted energy and significantly increased wear of system components. Variable speed drive technology is a cost effective method to match driver speed to load demands and is an excellent opportunity to reduce operating costs and improve overall efficiencies in your application.
