Electric motors are estimated to consume about 65% of the electrical energy consumed by industry. Moreover, energy costs over the typical life cycle of a motor can be as high as twenty times the original capital cost of the motor. Energy efficient motors thus offer an opportunity to significantly reduce energy costs and their collateral environmental effects. Increasingly, there is a strong economic-and environmental-case for choosing high efficiency motors over conventional ones. Instead of repairing or rewinding a failed motor, organizations may profitably consider replacing them with energy efficient motors or motor driven systems that can bring about significant reduction in energy consumption.
