Analysis and suggestion on the future development direction of China electric motor

China motor industry development strategy research report on the world motor industry development present situation, the Chinese motor industry policy and market operation, on the basis of the development of motor industry chain has carried on the thorough analysis, put forward in the next few years China's motor industry development trend, for the local government and enterprises provide decision-making reference layout motor and the upstream and downstream industries.

Motor product variety, a wide range of applications

There are a wide variety of motor products, which can be divided into various types according to the parameters such as model, specification, power, shaft extension, insulation, encoder, speed switch, thermal sensor, heating belt and so on. For the sake of simple division of motor products, on the one hand, motor is divided into large motor, medium and small motor and micro motor according to industry practice. On the other hand, the motor is divided into ordinary standard motor and special motor.

Main application field of motor

Motor application range is very wide, covering all aspects of production and life, different motor should be different functional requirements and appear. A large number of motors are used in machine tools, rolling mill, blower, printing press, water pump, pumping unit, crane, conveyor belt, production line and other equipment. The elevator and rolling ladder of high-rise building are driven by electric motor, and the automatic door and revolving door of hotel are also driven by electric motor. Electric cars are driven by electric motors. In medical equipment, cardiac motor, X-ray machine, CT, dental surgery tools, dialysis machine, ventilator, electric wheelchair, etc., are also inseparable from motor as power.

High efficiency and energy - saving electrical machinery has become the global motor industry consensus

Under the background of global reduction of energy consumption, efficient and energy-saving motors have become the consensus of the development of the global motor industry. Countries such as the United States, Canada, Mexico, Brazil, Australia and New Zealand have successively formulated energy efficiency standards and labeling systems for electric motors, and defined the time schedule, implementation method and implementation scope for motor energy saving and efficiency improvement. For example, the NEMAPremium ultra-high efficiency standard established by the United States above the EPACT standard, the eu-cemep standard of the European Union, the Australian AS/NS1359.5 -- 2000 and the Chinese GB18613 -- 2012 standard.

In the aspect of energy saving of electric motor system, China has issued some guiding policies successively, especially after 2008, the speed of elimination of inefficient electric motor and driving equipment was accelerated, and the promotion of efficient energy-saving electric motor was strengthened. In May 2009, the ministry of finance and the national development and reform commission included the application of efficient and ultra-efficient electric motors in the project of benefiting the people. In 2009 and 2012, the ministry of industry and information technology released two batches of "catalogue of obsolete electromechanical equipment (products) with high energy consumption". In May 2010, the ministry of finance and the national development and reform commission included high-efficiency motors into the implementation scope of energy-saving products benefiting the people project. In the 12th five-year plan for industrial energy conservation and the 12th five-year plan for the development of energy-saving and environmental protection industries, the energy conservation of the motor system is included in the nine major projects of energy conservation, and the high-efficiency energy-saving motor technologies and equipment such as rare earth permanent magnet coreless motor and cast-copper rotor technology for motors are demonstrated and popularized.

The development of new energy vehicles drives the rapid growth of drive motors

In 2011, the growth rate of new energy vehicle ownership was 59.58%. Under the stimulus of policies such as the development plan of energy saving and new energy vehicle industry (2012-2020), the market of China's new energy vehicle industry was expected to be good, which led to the rapid growth of the size of the driving motor market. At present, there are about a dozen domestic bus driving motor systems, represented by sem and tianyuan motor. Among them, hybrid electric passenger car is the main electric passenger car product at present, and the drive motor system used in pure electric passenger car has higher requirement on power, and the production enterprises are less.

Investment opportunities and development Suggestions for China's electrical industry

(1) high-efficiency energy-saving motors are the inevitable direction of the development of the motor industry

Energy conservation and emission reduction are the key contents of the work of the Chinese government in recent years. Among them, industrial energy conservation is the top priority of energy conservation and emission reduction. In addition, the energy conservation of electrical system is the most important content of industrial energy conservation.

In the 12th five-year plan for industrial energy conservation and the 12th five-year plan for the development of energy-saving and environmental protection industries, the energy conservation of the motor system was included in the nine major projects for energy conservation, and it was clearly proposed to demonstrate and popularize such high-efficiency energy-saving motor technologies and equipment as the permanent magnet coreless motor and the casting copper rotor technology for motor. The detailed rules for the promotion and implementation of high-efficiency electric motors for energy-saving products benefiting the people, issued in 2010, have improved the promotion strength of energy-saving electric motors and specified the scope of financial subsidies. The "energy efficiency limit value and energy efficiency rating of small and medium-sized three-phase asynchronous motors (gb18613-2012)" standard issued in September 2012 improved the energy efficiency indicators of all levels of motors, eliminating the efficiency requirements of the motors at 75% rated output power. The vigorous promotion at the policy level and the huge market growth space bring a lot of investment opportunities for energy-saving and environment-friendly materials and energy-saving motors.

(2) high-efficiency energy-saving motors will drive the rapid development of the industrial chain

The upstream of the industrial chain of high-efficiency and energy-saving motors are raw material suppliers such as copper, aluminum, silicon steel and permanent magnet materials, while the downstream are channel sellers and efficient motor application manufacturers. The huge market demand space will make the upstream and downstream of the industrial chain adjust to the "high efficiency and energy saving of motors", the upstream supply structure will be adjusted, and the enterprises with advantages in the production of high-efficiency motor specialized raw materials and parts will gain more market shares and higher yields. With the large-scale production of high-efficiency motors, their supply will be enlarged, cost and price will be relatively reduced, and downstream manufacturers will widely use high-efficiency motors to upgrade the original products.

(3) local governments should step up the formulation of industrial plans and strengthen the construction of industrial supporting facilities

Local governments should plan the development of the motor industry from a forward-looking and strategic perspective, analyze the current situation, advantages and disadvantages of the industry in depth according to the local basic situation, formulate the development plan for the motor industry and implement the industrial development safeguard measures. From the perspective of energy saving, consumption reduction and industrial chain optimization, the industrial development plan promotes the development of the motor industry towards high efficiency and energy saving. At the same time, local governments should also establish the awareness of serving enterprises and promoting long-term sustainable development of enterprises, strengthen the construction of industrial supporting capacity, and provide land, financing and fiscal and tax policy support for motor enterprises to reduce operating costs and optimize operating environment.
