The slot wedges of small and micro motors can be divided into drive motors and control motors according to their functions, involving precision machining, chemical processing, magnetic material processing, winding manufacturing, insulation treatment and other processes, and belong to technology and capital intensive industry. In production and daily life, small and micro motor slot wedges play an indispensable and important role.
Before the 1980s, a small number of companies or military enterprises from countries such as the United States, Britain, France, and the Soviet Union monopolized the world precision micro motor slot wedge market. Subsequently, countries such as Japan, Germany, and Italy developed rapidly, and their product levels were among the world's advanced. After years of development, domestic enterprises have made significant progress and have become a major producer of slot wedges for small and micro motors. However, compared to the development of foreign micro motors, there is a significant gap between domestic enterprise products and foreign ones in terms of power density, operating accuracy, and product life. Improving product quality and competing for high-end market share is also an important focus for the development of domestic enterprises.

The industry with the most application of slot wedges for small and micro motors is the information industry, accounting for about 31% of the market share, followed by the automotive industry, accounting for about 26%, and household appliances accounting for about 23%. The growth rate of production in the automotive industry has declined. Considering the increase in the number of small and micro motor applications brought about by the upgrading of automotive configurations, the growth rate of the number of small and micro motors used in the automotive industry will be better than the growth rate of the entire vehicle market; The demand for updates and generations in the information industry has made the demand for small and micro motors relatively stable; The growth of the household appliances and audio equipment industry has slowed down, and there is a high probability of maintaining positive growth in the next two years. Therefore, the demand for small and micro motor slot wedges in traditional advantageous industries is expected to maintain a stable and increasing trend in the coming years.
The arrival of the intelligent era has opened up a great space for the new demand for slot wedges in small and micro motors. With the continuous deepening of industrial modernization and equipment (including weapons) modernization, automation and information integration; The construction of digital chemical plants has made small and micro motors more widely used. Micro motors have evolved from simple starting control and providing power in the past to precise control of their speed, position, torque, etc. In addition, there are 430 million households in China that provide vast space for the development of smart homes. Studies have shown that the average household ownership of small and micro motors in China is about 20-40 units, far lower than the average household ownership of 80-130 units in developed countries.
Based on the requirements of the intelligent era for small and micro motor slot wedges, companies with the following inherent characteristics are expected to have the ability to design and develop micro motor slot wedges while also possessing fine machining capabilities; Capable of producing products with high power density and low energy consumption, with products developing towards permanent magnetization and brushless; Capable of producing mid to high-end stepper motors and servo motor slot wedges.
