The motors are widely used in industrial, commercial, utilities and household appliances, and other fields, as fans, pumps, compressors, machine tools and other equipment, power. In general, the industrialized countries and developing countries, the power consumption of the motor in the total electricity consumption accounts for a sizeable proportion. Since the 1970s, the first energy crisis, the United States on an extensive survey of the motor electricity consumption. According to the U.S. Department of Energy statistics, the motor power consumption accounted for industrial electricity use 2/3 of its total electricity use 1/2; motor energy transferred 20% of its total primary energy consumption. EU statistics show that in 1992, the year the EU's total electricity consumption of 1.7 trillion kWh, which motor electricity consumption was 719 billion kWh, 42% of the total electricity consumption.

    At present, most of the country's electricity production is still the main thermal power, a substantial portion of the Earth's greenhouse gas emission of CO2 and other gases in its production process, have a great impact on the climate and environment. The expert estimates, the total electricity consumption of the motor of the United Kingdom in 1995 to 130 billion kWh, carbon emissions into the air to produce these energy of 24 million tons, equivalent to 17% of the total carbon emissions of all energy in the UK. According to the 1997 Kyoto Protocol, countries have to reduce greenhouse gas emissions: 8% reduction in the emission levels of the European Union from 2008 to 2012 than in 1990, which the United Kingdom decreased by 12.5%. As the largest developing country, China is also actively take measures to control and reduce CO2 emissions. The motor energy efficiency energy savings brought about by raising the level of greenhouse gas emissions can be greatly reduced, the motor energy conservation for climate and environment protection and conservation of natural resources will play an important role.
