subject: The Necessity And Urgency Of Electric Motor [print this page]
In China, about one billion units of AC motor have been put into use, accounting for per cent of 60 in the total load of power consumption , accounting for 70 per cent of the industrial electricity. Authority of the Chinese Energy Agency report noted that about 60% of our motor is lower than the design load rating of60 per cent of under-load condition to run the motor running in this state, up to 30 per cent of electricity is wasted out, China has formulated the Energy law of the People's Republic of China and related energy-saving technological transformation, such as loans and tax preferential policies to encourage enterprises to adopt new technologies to reduce energy consumption.
According to the Fourth National motor protection and electrical energy-saving technologies meeting information, the national motor in service, there are 400 million KWof high-energy motor (loss account for the rated output of 10 per cent to per cent of 23),of which one hundred cent of 50, belongs to the need to eliminate the energy-intensive products; the country each year burned the motor number of the more than 200,000, the cost of repairs up to 20 billion yuan caused by downtime losses of up to 100 billion yuan.
Motor energy-saving technical means of two aspects: one is the motor body structure design improvement and adoption of new materials, renovation of the old motor; the other hand, is to improve the external environment of the motor is running. Dr. Paul power-saving technology is adopted to improve the external motor operating environment for dynamic power management is one of the major energy-savingtechnologies of the two complementary AC motor and inverter.
