China Electric Motor , The Development Trend Of China'S Motor Industry
Recently, "China Electric Motor Industry Development Strategy Research (2013)" was released in Beijing. Based on the research on the development status of the world's motor industry, China's motor industry related policies and market operations, the report made an in-depth analysis of the development of the motor industry chain. The development trend of China's motor industry in the next few years will provide decision-making reference for local government and enterprise layout motor and upstream and downstream industries.
China Electric Motor Description: High-efficiency motors take measures from design, materials and processes, such as reasonable positioning, rotor slot number, fan parameters and sinusoidal windings to reduce losses, and efficiency can be increased by 2% - 8%, with an average increase of 4 %. In 2002, China's total motor capacity was about 400 GW, of which nearly 80% was small and medium-sized, with an annual electricity consumption of 660 TW·h. The average efficiency of small and medium-sized motors is 87%, and the international advanced level is 92%. The power saving potential of China's small and medium-sized motors is about 12TW·h.
A wide range of motor products, a wide range of applications
There are many types of motor products, and various motors can be divided according to different parameters such as model, specification, power, shaft extension, insulation, encoder, speed switch, thermal element, and heating belt. In order to simply divide the motor products, on the one hand, according to industry practice, the motor is divided into large motors, small and medium-sized motors and micro-motors; on the other hand, the motors are divided into ordinary standard motors and special-purpose motors according to the specificity of the motors.
Basic type of motor
The application range of the motor is very wide, covering all aspects of production and life, and different motors should appear with different functional requirements. Machines, rolling mills, blowers, printing presses, pumps, pumping units, cranes, conveyor belts, production lines and other equipment use a large number of electric motors; elevators and escalators for high-rise buildings are driven by electric motors, and automatic doors and revolving doors of hotels are driven by electric motors; Cars are driven by electric motors; heart motors, X-ray machines, CTs, dental surgery tools, dialysis machines, ventilators, electric wheelchairs, etc. in medical equipment are also inseparable from electric motors.
High-efficiency and energy-saving motor has become the consensus of the global motor industry development
In the context of reducing energy consumption globally, high-efficiency 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 energy efficiency labeling systems for electric motors, and clarified the timetable, implementation methods and implementation scope of motor energy conservation and efficiency improvement. For example, the NEMA Premium ultra-high energy efficiency standard developed by the United States on the EPACT standard, the EU's EU-CEMEP standard, the Australian AS/NS1359.5-2000 and the Chinese GB18613-2012 standard.
In terms of energy saving in motor systems, China has successively introduced some guiding policies, especially after 2008, speeding up the elimination of low-efficiency motors and dragging equipment, and strengthening the promotion of high-efficiency and energy-saving motors; in May 2009, the Ministry of Finance and the State The National Development and Reform Commission has included high-efficiency and ultra-efficient motor applications in Huimin Engineering; in 2009 and 2012, the Ministry of Industry and Information Technology has also released two batches of “high-energy-consuming backward mechanical and electrical equipment (products) elimination catalogues; May 2010, fiscal The Ministry of National Development and Reform Commission has also incorporated high-efficiency motors into the implementation scope of energy-saving products for the benefit of the people; the "12th Five-Year Plan for Industrial Energy Conservation" and the "12th Five-Year Plan for Energy Conservation and Environmental Protection Industry Development" have included energy saving in the motor system into key energy-saving projects. The large-scale project proposes to promote high-efficiency and energy-saving motor technology and equipment such as rare earth permanent magnet ironless core motor and cast copper rotor technology for electric motor.
The development of new energy vehicles drives the rapid growth of drive motors. The growth rate of new energy vehicles in 2011 is 59.58%. Under the stimulus of “Energy Conservation and New Energy Vehicle Industry Development Plan (2012-2020)”, China's new energy automobile industry market Expectations are good, driving the market for drive motors to grow rapidly. At present, the domestic bus drive motor system is represented by CSR Times and Tianyuan Motor, and there are about a dozen. Among them, the hybrid bus is currently the main electric bus product, and the drive motor system used on the pure electric bus has higher power requirements and fewer production companies.
