Motor as the electric energy conversion or transfer of electromagnetic devices, alternator machine the main role is to produce drivers, power source of the reducer. The motor is directly related to energy consumption and service life of the reducer. China's "12th Five-ten key energy conservation projects will also be included in the motor system energy conservation projects, high efficiency motor to promote the meeting held in March this year. From the current point of view, China's motor design technology has reached maturity, motor exporting country. Fewer motor manufacturers of the United States and other developed countries, almost all rely on imports, China's motor industry has brought great market potential, export prospects for China's motor industry is very broad.

In late 2011, China's motor manufacturing industry enterprises of 2260, the sector's total assets amounted to 559.55 billion yuan, an increase of 25.00%. ball bearing offers newspaper network data: 2011, China's motor manufacturing enterprises above designated size industrial enterprises realized main business income of 607.66 billion yuan, an increase of 20.79%; total profit of 36.888 billion yuan, down 0.20 percent.

Motor manufacturer in China because the domestic market demand, the design of the motor from the appearance point of view size was relatively large. Compared with foreign large motors, consuming more raw materials, cost of production is naturally high up. Large motor development trends in the international arena is now portable, simple, our large motor size and price do not have a competitive advantage in China have yet to upgrade the ability of large motor design. Only enhance the international competitiveness of China's domestic motor manufacturing companies, China's motor manufacturing industry will become a global supplier of the motor.

 China's motor industry should step up co-ordinated .commutator motor machine management of the design and manufacturing capabilities, and strengthen the independent innovation research and development of standardization work. We should focus on energy efficient use of energy-saving environmental protection efforts focus on large motor development goals and technical requirements of the specification motor industry to be able to adapt to the needs of the market economy and the national industrial development.
