Industry characteristics

The micro-motor refers to a motor with a diameter of less than 160 mm or a rated power of less than 750 mW or a special purpose. The micro-motor integrates the high-tech industry of many-door disciplines such as motor, micro-electronics, power electronics, computer, automatic control, precision machinery and new materials, especially the application of electronic technology and new material technology to promote the technological progress of the micro-motor.

There are many kinds of micro motors (more than 5000 kinds), the specifications are complicated, the market application field is very wide, involving the national economy, national defense equipment, all aspects of human life, all the occasions where electric drive is needed, we can see the micro special motors.

the invention relates to a micro-motor manufacturing process, relating to the process technology of precision machinery, fine chemical engineering, fine processing, magnetic material treatment, winding manufacture, insulation treatment and the like, It's a strong investment industry.

In short, micro motor industry is labor-intensive and technology-intensive high-tech industry.

Industry review

China's micro motor industry was founded in the late 1950s. In order to meet the needs of national defense weapons and equipment, it has gone through the stage of imitation, self-design and research and development. Up to now, it has a development history of more than 40 years. It has formed a complete industrial system of product development, large-scale production and key parts, key materials, special manufacturing equipment, and test instruments. According to statistics, there are more than 1000 micro-special motor manufacturers in China, with more than 100000 employees and a total industrial output value of more than 10 billion yuan. Micro motor industry has become an indispensable basic product industry in the modernization of national economy and national defense.

Current situation of industry

The domestic demand of micro-motors has been growing since the 1980s. In China, more than 50 production lines have been introduced to realize the large-scale and large-scale production of 25 large-scale,60-series,400 varieties and 2000 micro-motors. The main products are the brush permanent magnet DC motor, the small power AC motor, the AC/ DC series motor, the cover pole motor, the stepping motor, the vibration motor (the mobile phone) and so on.

In 1999, China's micro-motor output is about 3 billion, of which the output of the private and state-owned enterprises is about 250 million, the output of the sole-owned enterprise is about 1.2 billion, the output of the Hong Kong region is about 1.4 billion Taiwan (1.2 billion Taiwan companies), and the output of the Taiwan region is about 180 million. The production capacity in 2000 is about 3.9 billion. Accounting for 60 per cent of global total production.

The micro-motor with high technology content, such as precision brushless motor, high-speed synchronous motor, high-precision stepping motor, chip-shaped winding brushless motor, high-performance servo motor and new principle, has not yet formed commercial or batch production capacity in China. So the domestic high-precision micro-electric machine also relies on the import. According to the customs statistics, the average annual exchange rate for 1995-2000 increased by 26.9 per cent, with an increase of 4.81 per cent in 2001, and an increase of $11.97 billion.

the situation of the market

With the continuous development of the world economy and the improvement of people's living standards, micro-motor, as an indispensable basic mechanical and electrical product, has not only low, medium and low investment labor-intensive products, but also high investment technology-intensive products which adopt advanced manufacturing technology, new electronic technology and new material technology applications, and has been integrated into the globalization of production and sales.

In 2000, the global micro-motor market is over 65 billion, mainly distributed in the fields of audio-visual, office automation, electric vehicles (including automobiles), home appliances and air-conditioners. Table 1 lists the state of the world's micro-motor market distribution in 2000 and the occupancy of Japan (it should be noted here that in the most part of Japan's market share, low-and low-grade micro-motors have been transferred to the mainland of China). With the improvement of people's living standard, the micro-motor market is developing rapidly. In general, the number of micro-motors per family can measure the level of a country's modernization level. From Table 2, it can be known that every home in the developed country has the history of increasing the number of micro-motors and the trend of future growth, and the market demand is developing rapidly, There is a huge market.

In Japan, the micro-motor for AV and OA is light, thin, small in size, small in size, small in size, high in efficiency of the micro-motor for air-conditioning, and is in the leading position in the world. And occupies a large part of the market of the world high-grade micro-motors.

The future of the industry

China has grown by 18.6% from 1995 to 2000, with a decrease of 6.02% over the year 2000. The U. S., Japan's economy has suffered a serious setback in the global economy, a major factor in the decline in exports in 2001, in the wake of the American "9.11" incident. Table 3 lists the situation of the export of the micro-motor for the period 1995-2001 of the customs statistics. In 2000, the world's micro-motor market is about 6.5 billion Taiwan, with China's exports of 27.26 billion Taiwan, accounting for about 42% of the international market, among which, the toy motor is 32151,000 sets, the micro-motors of less than 37.5W are 238236,000, and the two-purpose motor of 37.5W is 1970.6 million sets, The direct current motor of <750W, the generator 237.7 million sets.

After China's entry into WTO, China's micro motor industry has entered the global economic environment in which opportunities and challenges coexist. Only by working hard and fiercely can we win a greater share of the international market.
