As we all know, the motor is the main power consumption in the national economy, and energy conservation is an eternal theme of the motor industry. Some experts said that China's energy shortage is mostly due to waste of energy and improper use. At present, China's industrial energy consumption accounts for about 70% of the total energy consumption, of which the motor energy consumption accounts for about 60%~70% of the industrial energy consumption. According to the survey, China's IE1 class motor market share of nearly 90% of the market share, and enterprises to achieve IE2 above the proportion of energy-efficient motor only 8%. This has caused great waste to the whole society. Therefore, the development of high efficiency motors is one of the important measures to improve energy efficiency. It is also necessary to meet the needs of China's development. The motor is very important to the Chinese market. China holds 21.5% of the global motor market. In the next five years, the Chinese market will grow faster than other countries, and it will grow faster than Europe and america." IMS researcher at this year's SIAF Exhibition Conference on transmission technology said. According to the IMS research, the demand for high power motors is increasing all over the world, including the United States, Europe, China and other regions. Although the price of high-power motors is expensive, the market sales have increased. In the next five years, higher growth is expected, and sales will double in 2011, or $2 billion 600 million in 2015.
