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 United States has developed the NEMAPremium ultra-high energy efficiency standard 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
In 2011, the growth rate of new energy vehicle ownership was 59.58%. Under the stimulus of “Energy Conservation and New Energy Vehicle Industry Development Plan (2012-2020)”, China’s new energy automobile industry market is expected to be good, driving the market of drive motor to be rapid. increase. 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.
