The intelligentization of the motor industry is a necessary trend
With the development of China's industrial economy, motor has been widely used. According to statistics, the motor system power consumption accounts for about 60% of the national electricity consumption, of which fan electricity accounts for 10.4% of the national electricity consumption, pump motor accounted for 20.9%, 9.4% of the compressor, but more than 80% The efficiency of the motor products is 2% -5% lower than that of the foreign advanced level, and the efficiency of the motor system is 10% -20% lower than that of the foreign advanced level.Therefore, there is a huge demand in improving the efficiency of the motor system and strengthening the system energy saving management.
At present, China's total installed capacity of electric motors has reached more than 400 million kW, the annual power consumption of 1.2 trillion kWh, accounting for 60% of the total electricity consumption, accounting for 80% of industrial electricity consumption, including fans, pumps, The total capacity of more than 200 million kW, the annual power consumption of 800 billion kWh, accounting for about 40% of the total electricity consumption, so the energy requirements on the motor greatly, but also the best energy-saving effect of the place. With the new motor design, new technology and new materials, by reducing the electromagnetic energy, thermal energy, mechanical energy loss to improve the output efficiency, energy efficient motor than the traditional motor efficiency of about 3% -5%, currently reached 2 energy efficiency indicators of the motor accounted for Less than 10%, so its development space is vast.
"In the notice of the organization and implementation of the motor energy efficiency improvement plan (2013-2015)", by 2015, to achieve the upgrading of motor products, 50% of the low-voltage three-phase cage asynchronous motor products, 40% of high-voltage motor products to achieve high efficiency Motor energy efficiency standards; the cumulative promotion of efficient motor 170 million kilowatts, eliminated in the use of low-efficiency motor 160 million kilowatts, the implementation of the electrical system energy-saving technological transformation 100 million kilowatts, the implementation of the elimination of motor re-manufacturing 20 million kilowatts. Is expected to achieve savings of 80 billion in 2015, equivalent to 26 million tons of energy-saving standard coal, emissions of 68 million tons of carbon dioxide.
With the power electronics technology, computer technology, microelectronics technology and control theory of the development and application of small and medium-sized motor applications are increasingly widespread. In order to achieve high quality, high efficiency and low cost operation, small and medium-sized motor in a variety of different conditions with the computer, motor controller, power converter, sensor and many other aspects of the connection, but also often with the post-implementation agencies and load (Such as various mechanical, hydraulic, pneumatic devices) together.
In this way, the motor is not a component-level actuator, but a complete mechanical and electrical integration system that achieves a predetermined function. International ABB, Siemens, Mitsubishi and so on have been developed from the motor manufacturing enterprises for the internationally renowned motor and control system manufacturing enterprises, its product range from the motor as the core, extended to the inverter, soft starter and other motor control areas, reflecting the A larger technical advantages and competitive advantage, occupy a larger market share. China's motor manufacturing enterprises have begun to pay attention to motor control technology, but to achieve the motor system parameters to optimize the matching and control integration, and the introduction of mature products, need to make hard work.
Motor and system efficiency has become one of the largest energy-saving industries. International governments and organizations have studied energy efficiency programs for various motor systems in different application areas and in different industrial sectors, developed energy efficiency guidelines, standards and regulations, and developed relevant green energy-saving products such as: IEC unified global motor energy efficiency And test methods standards: the European Union EuroDEEM, the United States MMASTER motor system energy efficiency platform; the EU's ecological design plan.
China is actively promoting and supporting the efficient motor and electrical system energy-saving projects carried out and implemented. Efficient, ultra-efficient small and medium-sized motor, speed motor, motor system energy-saving control products such as development and electrical and green energy-saving technology research has become a development trend.
