Analysis of Current Status of Permanent Magnet Motor Industry Development in China in 2018

The permanent magnet motor uses permanent magnets to generate the magnetic field of the motor, eliminating the need for excitation coils and excitation current, and has a high efficiency and simple structure. It is a very good energy-saving motor. With the advent of high-performance permanent magnet materials and the rapid development of control technology, permanent magnet motors The application will become more extensive.

Global Market: Developed countries have mastered the high-end technology of permanent magnet motors, and Japan has led the development of high-precision permanent magnet motor technology.

The well-known brand companies in Japan, Germany, the United States, the United Kingdom, Switzerland, Sweden and other countries rely on their decades of permanent magnet motor manufacturing experience and key process technologies, which still affect the development of the world's permanent magnet motors, and most of the high-end, precision controls New permanent magnet motor technology and products. In particular, Japan, with its precision machining technology, has great advantages in small and medium-sized motors and represents the advanced level in the world, leading the development of high-end precision permanent magnet motors.

Japan's permanent magnet motor manufacturers occupy an important position in the international permanent magnet motor market because of their mastery of high-end technologies. They are at the top end of the market and have the industry's most advanced technologies and products. Japan’s leading position in electronic control and production processes is one of the leading countries for micro-motor equipment both in production and technology.

Japan has carried out a lot of research and development work on the high-efficiency, quietness of permanent-magnet motors, and the high performance of permanent-magnet motors used in industrial servos. Therefore, it has a great advantage in technology, and the micro-motor equipment produced has high control accuracy. With competitive advantages such as low power consumption, long life, and low cost and small size, it is also at the forefront of the world in terms of technology, and it occupies most of the world's high-end permanent magnet motors.

In addition to Japan, permanent magnet motors in the United States are also at the leading level in the world. The development of the permanent magnet motor industry in the United States is mainly focused on military micro-motors. The level of scientific research and product development of military micro-motors in the United States is in the leading position in the world. The vast majority of micro-motors used in military equipment and electronic devices in Western countries are made up of several US The supply of major manufacturers, micro-motor American standards have become an international standard. The main brands of permanent magnet motor market in the United States include parker motors, bodine motors from the United States, Pacific motors from the United States, and LEESON motors from the United States.

Global Economy With the rapid development of information technology, countries have entered the technological stage and popularization stage of industrial automation, office automation, home modernization, agricultural modernization, and modernization of military weapons and equipment. Permanent magnet motors are an important basic element in these technologies and systems. With the increasing application of permanent magnet motors, the demand for permanent magnet motors is increasing.

With the rapid development of new energy vehicles, smart homes and other fields, increasing the demand for permanent magnet motors, the global sales of permanent magnet motors continue to increase. With the development of modernization, the development prospects of the global permanent magnet motor industry are more optimistic.

Application Market: The demand for permanent magnet motors in the downstream market continues to grow, and permanent magnet motors have a large application prospect.

On January 18, 2018, in the TK887 and TK883 wells of the Northwest Oilfield, technicians from the Power Supply Management Center and the Third Oil Production Plant tested the permanent magnet synchronous motors that replaced the asynchronous motors. Tests have shown that, compared to asynchronous motors, the power factor of a permanent magnet motor is more than doubled and the operating current is reduced by nearly 50%. After calculating only one well TK887, one year can save about 10,000 degrees of electricity, saving nearly 105,000 yuan in electricity costs. At present, there are about 1300 pumping wells in the Northwest Oilfield, all of which are motor-renewable, with an annual cost reduction of more than 5 million yuan. This test provides a solid technical basis and reliable basic data for the replacement of asynchronous motors by permanent magnet synchronous motors in the Northwest Oilfield.

Judging from the current technological advantages, permanent magnet synchronous motors have become the mainstream. It is worth noting that although the asynchronous motor is not dominant in terms of weight and volume, it has a wide speed range, low cost, simple process, and reliable operation. As for the impact of the weight on the cruising range, if the battery life is greatly increased in the future and the volume optimization of the asynchronous motor is done well, it will inevitably have a strong impact on the permanent magnet synchronous motor.

On January 5, 2018, the China Association of Automobile Manufacturers and the China Rare Earth Industry Association held an inaugural meeting on the cooperation mechanism for the upstream and downstream cooperation of rare earth permanent magnet materials for drive motors for new energy vehicles. The director of the Department of Raw Materials Industry of the Ministry of Industry and Information Technology stated that the drive motor is the “heart” of new energy vehicles, and rare earth permanent magnetic materials are the material of choice for drive motors. The rare earth permanent magnet drive motor can greatly reduce the weight of the motor, reduce the size of the motor, and improve work efficiency. The establishment of an upstream and downstream cooperation mechanism will help bridge the gap between the development of new energy vehicles, drive motors, and rare earth permanent magnet materials, and achieve mutual benefit and win-win results across the entire industry chain. From the two aspects of policy and technology, permanent magnet motors will usher in a period of development opportunities.

Under the background of the continuous expansion of the industry's downstream application market and continuous advancement of technological innovation, the Forward-looking Industry Research Institute expects that the market size of the permanent magnet motor industry will exceed RMB 135 billion by 2023, and the application prospect of permanent magnet motors will be large.
