The development of China's inverter market in the next five years

The "12th Five-Year Plan for Comprehensive Energy-saving and Emission-reducing Work Program" proposes to insist on reducing the intensity of energy consumption, reasonably controlling the total energy consumption, promoting the combination of technological advances, and greatly improving energy efficiency. With the launch of energy-saving and emission-reduction work, a group of related industrial energy-saving companies such as inverters and energy-saving motors will be the beneficiaries under the stimulation of relevant national policies. The annual electricity consumption of our country's motors exceeds 2 trillion kilowatt-hours, which accounts for about 60% of the country's electricity consumption. However, the market share of high-efficiency energy-saving motors is less than 3%, and the overall operating efficiency of motor systems is about 20% lower than in developed countries. If the newly-increased motor and drive system each adopts high-efficiency energy-saving products, the optimized design of the motor system can save hundreds of billions of kilowatt-hours of electricity annually and reduce hundreds of tons of carbon dioxide, which can effectively promote the development of energy-saving and environmental protection industries.

Motor energy-saving mainly depends on frequency conversion, so as to achieve the effect of improving motor efficiency and energy saving. The power saving rate of the motor system using the inverter is generally about 30%, and that of some high occasions can reach 40%-60%. Compared with the medium- and low-voltage inverter market, high-voltage inverter market concentration is higher, and the market share of domestic manufacturers is high, coupled with the "Twelfth Five-Year Plan" comprehensive energy-saving emission reduction work plan issued by the State Council, explicitly requested to accelerate the promotion The promotion and application of high voltage frequency control technology. Therefore, the high voltage inverter market has a good future.

China's small and medium-sized motor industry policy is to promote energy-efficient motors at the national level. Compared with ordinary motors, energy-saving and high-efficiency motors have an average loss reduction of 20% and an efficiency increase of 2% to 7%. Ultra-efficient motors have an average increase of 2% over energy-efficient motors. The energy conservation of the motor system has great influence on the implementation of the energy conservation and consumption reduction strategy. According to the provisions of the 1997 Kyoto Protocol, all countries in the world are facing high pressures for energy conservation and emission reduction. Therefore, laws and regulations for energy-efficient motors have been formulated separately.

Taking China as an example, the national electricity consumption in 2011 was about 4692.8 billion kWh. If medium and small-sized energy-saving and high-efficiency motors were used to increase 4%, the country could save 105.1 billion kWh, reduce 35.49 million tons of standard coal and reduce carbon dioxide by 9347. Million tons of emissions, 310,000 tons of sulfur dioxide emissions. First, it shows that China attaches great importance to improving motor efficiency. Second, small and medium-sized energy-saving and high-efficiency motors are currently used less in China. In addition, good small and medium-sized energy-saving and high-efficiency motors mainly rely on imports and are expensive. In addition, most of the domestic companies are "forgettable" because of the high cost of materials for the production of small and medium-sized energy efficient motors. This requires the state to increase its support for domestic motor manufacturing companies, so that domestic products as soon as possible to form a market competitiveness.

High-efficiency and energy-saving motors refer to high-efficiency motors of general-purpose standard motors. Energy efficient motors use new motor designs, new processes and new materials to improve output efficiency by reducing the loss of 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 generally be increased by 4% on average. Regrettably, although high-efficiency motors have been on the market for many years, user demand has not been very strong. At present, the market share of high-efficiency motors in China is very low, less than 10%. Therefore, under the promotion of relevant national energy conservation policies, the future of the high voltage inverter market is promising.

According to relevant data, in 2011, the market size of high-voltage inverters in China was about 5 billion yuan, accounting for only 6% of the potential market capacity. In the configuration of domestic medium- and high-voltage motors for fans and pumps, the deployment rate of high-voltage inverters was less than 20%. As environmental protection issues become increasingly important and industrial production requirements continue to increase, the demand for high-voltage inverter products will continue to increase, and the high-voltage inverter market will maintain 30% industry growth in the next three years.
