As early as 2010, as a world-renowned developer of alternative energy technologies, UQM announced that it has jointly developed a powertrain system for pure electric vehicles and hybrid passenger vehicles with BorgWarner, and powered the UQM PowerPhase. The propulsion system was integrated into BorgWarner's 3103eGearDrive electronically driven shifting bridge to provide CODA's pure electric front-wheel drive sedan. UQM's PowerPhase electric propulsion system has a peak power of 100 kW and a continuous output of 45 kW; its peak torque is 300 Nm and the continuous output torque is 160 Nm; this system weighs 46 kg, the largest The diameter is only 280 mm. This motor can be widely used in passenger cars, including mini-cars. The system also features optimized four-quadrant performance, dynamic torque, speed and voltage control, and its effective transmission rate in the power curve range is over 90%.
In contrast, at present, there are no enterprises that actually produce electric vehicle engines in China. Only a few companies are involved in the electric motor vehicle business, such as Wanxiang Group.
Domestic efficient motor contains hundreds of billions of markets
In recent years, although China has basically kept pace with the international level in the research and development of high-efficiency motors, the technological progress is very optimistic; but unfortunately, the domestic application of IE3 motors produced in China is too small, and most of them are used for export. It is not difficult to see that China still has huge challenges in high-efficiency motors.
As we all know, the electricity consumption of electric motors in the industrial sector accounts for about 75% of the total electricity consumption of the industry. Therefore, the energy saving of electric motors has become the key to industrial energy conservation. With the dual pressures of energy saving, emission reduction and environmental protection, energy-saving equipment represented by high-efficiency motors has attracted much attention in the market.
A high-efficiency motor is a motor with a high efficiency of a general-purpose standard motor. High-efficiency motors use new motor designs, new processes and new materials to improve output efficiency by reducing losses in electromagnetic, thermal and mechanical energy. Compared with standard motors, the energy-saving effect of using high-efficiency motors is very obvious, and the efficiency can be increased by 4% on average.
As early as 2008, China has listed the energy saving of motor system as one of the top ten energy-saving projects in the country. In 2009, it also applied high-efficiency and ultra-efficient motor applications to Huimin Engineering. At the beginning of last year, the National Motor Energy Efficiency Improvement Plan was introduced. The plan mentioned that in 2015, China will upgrade its motor products, and 50% of low-voltage three-phase cage asynchronous motor products and 40% of high-voltage motor products will be highly efficient. The standard of motor energy efficiency standards; the cumulative promotion of high-efficiency motors of 170 million kilowatts, the elimination of 160 million kilowatts of low-efficiency motors, the implementation of motor system energy-saving technology reform of 100 million kilowatts, the implementation of the elimination of motors and efficient remanufacturing of 20 million kilowatts.
In other words, it is estimated that in the year of 2015, 80 billion kWh of electricity will be saved, equivalent to saving 26 million tons of standard coal and reducing carbon dioxide emissions by 68 million tons. The Department of Energy Conservation and Comprehensive Utilization of the Ministry of Industry and Information Technology announced that it will officially implement the motor energy efficiency improvement plan nationwide. It plans to use three years to improve the energy efficiency of the national motor and promote the transformation and upgrading of the motor industry, including 30,000 of the annual electricity consumption of 10 million kWh or more. A number of industrial enterprises will be the focus of implementation of the plan. Based on this estimation, the implementation of this plan will drive the demand for high-efficiency motors and related equipment to nearly 100 billion yuan. In the future, with the advancement of the energy efficiency improvement plan, the demand for high-efficiency motors will gradually be released, showing an increasing year by year.
China's motor exports will gradually increase
At present, there are fewer and fewer enterprises engaged in traditional motor production in developed countries such as Europe and the United States. Under this background, Chinese motor companies may become their importers. The proportion of high-efficiency motors in domestic existing stock motors is less than 5%, and the high-efficiency motors produced are mainly sold abroad. According to industry sources, the proportion of high-efficiency motors in China is currently only 23% 25%.
Although China has gradually become a major motor manufacturing country and has mastered the production technology of high-efficiency and ultra-efficient energy-saving motors, overall, the competitiveness of the motor manufacturing industry is still weak, with large motor consumption and low energy efficiency. Gao Dongsheng, deputy director of the Department of Energy Conservation and Comprehensive Utilization of the Ministry of Industry and Information Technology, said that at present, there is still a big gap between China's overall energy efficiency level and foreign countries, especially the energy-efficient use of electrical equipment such as motors and transformers. The annual consumption of electricity by the motor accounts for 64% of the total electricity consumption of the whole society. The energy consumption of the motor in the industrial sector accounts for more than 70% of the total electricity consumption in the industrial sector. The energy efficiency of the motor system is much different from that of the foreign country, about 15%. About 20%.
According to the GB186132012 standard, China's current production and in-use motors are mostly Class 3 energy-efficient motors that are lower than the standard. The average efficiency is 87%, and the efficiency of high-efficiency motors already developed in developed countries has reached 91%. In addition, statistics from the Ministry of Industry and Information Technology show that at present, the proportion of high-efficiency motors in domestic motors is only about 5%. Some experts said that in the future, China should carry out in-depth research on energy-saving technologies for electric motors and their systems, such as research and development of high-efficiency and energy-saving motors, high-efficiency transmission systems, reasonable matching of motor systems, and system integration solutions for energy-saving of motor systems. On the other hand, it is necessary to formulate energy-saving related standards for motor systems, such as system energy-saving renovation guidelines, energy-saving testing and evaluation standards for motor systems in special fields. In addition, we must establish a motor system energy certification agency, such as market access certification, energy-saving product certification, energy-saving certification of various high-efficiency motor systems.
