Adaptive Electricity Energy Saving Strategy for Industrial Motors

This book discusses investigation on induction motor energy saving strategy particularly applied in the small and medium scale industry. A walk-through motor energy audit is carried out in a typical type of industry in Indonesia to collect some important data. Three induction motor energy saving strategies, by which energy efficient motor, variable speed drive, and capacitor bank are considered with respect to five criteria thought to influence the decision making in selecting suitable energy saving strategy for motor. Besides, motor energy saving is assessed using technical approach considering annual energy saving obtained from energy efficient motor, variable speed drive, and capacitor bank. In addition, assessments are carried out to find energy efficiency indicator such as specific energy consumption and energy intensity, as well as assessment on carbon dioxide emission and mitigation.
