An iron core is also a magnetic core. The iron core (magnetic core) plays an important role in the whole motor, which is used to increase the magnetic flux of the inductor, and has achieved the maximum conversion of electromagnetic power. The motor iron core is usually composed of a stator and a rotor. The stator iron core is the main component of the magnetic circuit of the motor. The stator iron core is made of silicon steel sheet. The iron core is also the part where the winding is placed. When the generator is running, the iron core will be subjected to the combined action of mechanical force, thermal stress and electromagnetic force.

In 2020, China's automotive motor iron core market size reached 175.83 million US dollars, and is expected to reach 678.83 million US dollars in 2027, with a compound annual growth rate (CAGR) of 17.32%. Overall, China's automotive motor iron core industry is a rising industry, because its downstream electric vehicles are expected to grow faster, we are expected to usher in greater growth in the future automotive motor iron core industry.

From the perspective of product types and technologies, welded iron cores are growing fastest, with a market size of $62.78 million in 2020 and is expected to reach $678.83 million in 2027. Bonded iron core accounted for the highest proportion, the market size of 78.85 million US dollars in 2020, accounting for 44.84% of the total automotive motor iron core market, and then gradually declined, which is due to the development trend of technology, bonded iron core will gradually be replaced by welded iron core.

From the perspective of product market application, pure electric vehicles account for a relatively high proportion, and the market size in 2020 accounts for 84.07% of the total automotive motor core market. The research team believes that hybrid electric vehicles are transitional products, which will be gradually replaced by pure electric vehicles in the future, and it is expected that the proportion of pure electric vehicles will continue to rise slowly in the next few years.

Automobile motor iron core is a key component of new energy automobile motor. From the current policy environment analysis of the industry, energy saving, environmental protection, electronic information technology is the future focus of the development direction of the auto parts manufacturing industry. In recent years, due to the aggravation of environmental pollution, the state has formulated a policy to promote the development of new energy vehicles. The development of new energy vehicles, the research and development of parts and production is the key. Therefore, in the development policy of new energy vehicles formulated by the State, it focuses on the development of auto parts and components, and also standardizes the development of China's auto parts industry to a certain extent. This is conducive to promoting the continuous standardized development of the automotive motor core industry.

From the national industrial planning, to energy saving and emission reduction requirements, and then to the manufacturing power strategy, the iron core as the core parts of automotive motors is a key area of support in China. The state will inevitably encourage the development of high-tech automotive motor core, thereby driving the development of China's energy-saving and environmental protection high-end equipment industry, put forward higher requirements for the automotive motor iron core manufacturing industry, play a leading role in the development of the industry, and bring important strategic opportunities for the business development of enterprises.
