Induction motor dominate industry & home applications, so these seem to be the major consumer of grid power.Is there any authentic figure about this?
Though it is depending on location and type of surrounding area, where load is to be supplied, yet minimum,70 to 75 % loading constituted, due to induction motors. 15 to 20 % industrial heating and furnace loading, and remaining 3 to 5 % domestic heating and lightening load.
90% Motor loads (99% of 90% is Induction Motor loads). Remaining 10% are lighting/other loads. Please access DOE(US), D-ARPA (US) reports with regard to your topic.
Three-phase squirrel-cage induction motors are widely used in industrial drives because they are rugged, reliable and economical. Single-phase inds.uction motors are used extensively for smaller loads, such as household appliances like fans induction motors are increasingly being used with variable-frequency drives (VFDs) in variable-speed service. VFDs offer especially important energy savings opportunities for existing and prospective induction motors in variable-torque centrifugal fan, pump and compressor load applications. Squirrel cage induction motors are very widely used in both fixed-speed and variable-frequency drive (VFD) applications. Variable voltage and variable frequency drives are also used in variable-speed service.
