Motors are widely used in today's world, and it can even be said that where there is movement, there may be motors. In the context of global reduction of energy consumption, high-efficiency and energy-saving motors have become the consensus of the development of the global motor industry. Motor is one of the indispensable components of mechanical equipment. At present, my country's motor industry has made great progress after more than 40 years of development, especially the rapid development since more than 20 years of reform and opening up. According to the data of the Ministry of Industry and Information Technology in 2011, my country's motor holdings are about 1.7 billion kilowatts, and the total power consumption is about 3 trillion kwh, accounting for 64% of the total power consumption of the whole society, of which the total power consumption of motors in the industrial sector is 2.6 trillion KWh, accounting for about 75% of industrial electricity. my country's new energy vehicle industry market is expected to be good. As of the end of 2013, my country's new energy vehicle production and sales volume totaled approximately 56,000. According to the "Energy-saving and New Energy Automobile Industry Development Plan", it is planned that by 2015, the cumulative production and sales of pure electric vehicles and plug-in hybrid vehicles will strive to reach 500,000; by 2020, the cumulative production and sales will exceed 5 million. From the perspective of the market scale of policy planning, my country's new energy automobile industry will usher in a rapid growth stage in the next few years. This phenomenon will drive the rapid growth of the drive motor market. In the context of global reduction of energy consumption, high-efficiency and energy-saving motors have become the consensus of the development of the global motor industry. In recent years, although my country has basically kept pace with the international level in the research and development of high-efficiency motors, it is not difficult to see that my country still has huge challenges in high-efficiency motors.
