Micro motors find extensive applications across diverse sectors, including household appliances, automotive, medical, new energy, electronic information, aerospace, and military. They play crucial roles in control and drive functions, making them indispensable electromechanical products in production and daily life. Taking China as an example, the micro motor industry originated in the late 1950s, initially meeting the needs of national defense weapons and equipment. Over the past 40 years, it has evolved through stages of imitation, independent design, and research and development, establishing a complete industrial system encompassing product development, mass production, and supporting key components, materials, and specialized manufacturing equipment and testing instruments. Statistics reveal that China has over 1,000 micro motor manufacturers and supporting factories, employing more than 100,000 individuals, with an industrial output value reaching hundreds of billions. The micro motor industry has become an indispensable foundational product industry in both the national economy and defense modernization construction.
Micro Motor Industry Chain
The micro motor industry chain consists of upstream raw materials, midstream production manufacturing suppliers, and downstream application areas. Upstream raw materials primarily include steel, copper, and enameled wire. Downstream applications span various fields, such as automotive, household appliances, communication, computers, robotics, aerospace, industrial machinery, and military.
Data indicates a high proportion of microelectronics in consumer electronics and household appliances, accounting for 29% and 26%, respectively. Automotive electronics and image processing account for 13% and 7%, respectively.
Trends in Micro Motor Development
Energy Efficiency and Environmental Friendliness: As concepts like energy efficiency, health, and environmental protection gain prominence, micro motors, being major energy-consuming components, are continually improving in energy efficiency, noise and vibration reduction, and electromagnetic interference.
Mechatronics Integration: With continuous applications of electronic technology, especially microelectronics, computer technology, material technology, automatic control technology, and biotechnology in micro motors, modern micro motors have evolved into a new generation of mechatronics systems with electronic computing as the control core, equipped with sensors and a series of power electronic devices.
Digitization and Intelligence: Micro motors achieve digitization, logic control, self-feedback, and self-adjustment by incorporating programmable controllers into their control units for speed and position control.
Innovations in Testing Technology: Due to the minuscule size of critical components in micro motors and the extremely subtle movements and displacements they generate, traditional testing methods fall short. New micro-mechanical quantity sensing measurement technology is necessary to meet evolving testing requirements.
Market Analysis of Micro Motors
Micro motors, as foundational electronic components, are ubiquitous in various electromechanical devices. However, they do not constitute final consumer goods. The primary demand comes from manufacturers of various electromechanical devices. The consumption of these devices is closely tied to the level of economic development. Developed Western countries are the largest consumer regions for micro motors, with an average of 80-130 micro motors per household. In contrast, developing countries have lower average ownership. For example, in Chinese urban households, the average ownership is around 30-60 micro motors, indicating significant growth potential for the micro motor industry.
On the domestic front, China's national policy development plan explicitly outlines the High-end Equipment Innovation Development Project, including aerospace equipment, marine engineering equipment, advanced rail transportation equipment, high-end CNC machine tools, robotics, modern agricultural equipment, high-performance medical equipment, and complete sets of advanced chemical equipment. These equipment categories heavily rely on micro motors, and their development and breakthroughs necessitate the accelerated growth of the micro motor industry, especially in high-end precision micro motors. On the policy side, starting in June 2021, the implementation of GB18613-2020 Motor Energy Efficiency Limits and Energy Efficiency Grades officially phased out motors below IE3 efficiency. Since 2011, China's micro motor industry has maintained overall high-speed growth. The increasing production capacity and the rising rate of domestication in electromechanical, electronic, and industrial control products have propelled rapid growth in industry demand. In 2021, the market size of China's micro motor industry reached 2702.6 billion yuan, and in 2022, it reached 2766.7 billion yuan, with a year-on-year growth of 2.37%.
The future market size is expected to gradually expand, with projections indicating that by 2028, the market size of China's micro motor industry will grow to 3192.9 billion yuan.Examining the competitive landscape of the micro motor industry, on the international stage, countries such as Japan, Germany, the United States, the United Kingdom, Switzerland, and Sweden stand out as production powerhouses for micro motors. China has emerged as a major producer, occupying over 70% of the global production. Joint ventures between Chinese and foreign companies have a distinct advantage with advanced technical support and well-established overseas market channels, outperforming domestic manufacturers. However, the domestic micro motor production belongs to labor-intensive industries, mostly comprised of small and medium-sized enterprises. Relying on inexpensive labor and ample raw materials, they provide low-cost products but often lack independent research and development capabilities, primarily focusing on mid to low-end and low-cost micro motors.
The trajectory of China's micro motor industry reflects not only robust growth but also a shift towards international prominence. As the industry continues to evolve, there is potential for further advancements and increased competitiveness on the global stage.
