The impact of low carbon economy on China's Ferrite Magnet industry

- Feb 22, 2019-

The strong demand for permanent magnet motors in the low carbon economy stimulates the growth of the permanent magnet market

One of the main energy consumption of the modern economy is the motor. In the United States, the motor has lost 63%-70% of the domestic electricity consumption, accounting for 23% of the total US electricity consumption. Many motors are even less than 50% efficient, so improving the efficiency of the motor is clearly an effective energy-saving measure. Permanent magnet motors are high-efficiency typical energy-saving and low-carbon industrial products. As energy-saving devices, they are widely used in various industrial transmission and rotating devices. In addition to rapid development in the traditional field, the permanent magnet will develop rapidly in the following fields.

(1) Renewable new energy: permanent magnet wind turbine

The development of wind turbines has become an important fulcrum for the rare earth permanent magnet industry. Direct-drive permanent magnet wind turbine technology has entered a mature stage. At present, the penetration rate of European and American markets is above 25%, while China only has 10%, but industry experts believe that in the future of China's wind power motors, direct-drive permanent magnet wind turbines The penetration rate will exceed that of developed countries in Europe and America, becoming the mainstream wind turbine, which will directly drive the demand for China's high-performance NdFeB Ferrite Magnet to grow at a compound annual growth rate of more than 20%. By 2014, the demand for NdFeB Ferrite Magnet will be It reached 9600t.

(2) Energy saving and emission reduction: ultra-efficient permanent magnet motor, speed-regulated high-efficiency permanent magnet motor

Ultra-efficient permanent magnet motors and speed-regulated high-efficiency permanent magnet motors are widely used in the production of inverter household appliances and industrial products, and become another focus of demand for the rare earth permanent magnet industry. In the case of inverter air conditioners, DC frequency conversion is 15%-30% less than AC frequency conversion, while China's inverter air conditioner market share is only 10%, and the Japanese market share is as high as 90%. If China's inverter air conditioners maintain an average annual growth rate of 30%, by 2014, the NdFeB Ferrite Magnet for inverter air conditioner brushless DC motors will reach 5,825t.
