The research and product level of US military micro-motors is in the world's leading position. Most of the micro-motors used in military equipment and electronic devices in Western countries are mostly from the United States. Main manufacturers supply, micro-motor US military standards have become an international standard. The main brands in the US permanent magnet motor market are parker motors, American bodine motors, American Pacific motors, and US LEESON motors.
Global economy With the rapid development of information technology, countries have entered the technical stage and popularization stage of industrial automation, office automation, family modernization, agricultural modernization and modernization of military weapons and equipment. As an important basic component of these technologies and systems, permanent magnet motors are becoming more and more widely used with the application of permanent magnet motors.
With the rapid development of new energy vehicles, smart homes and other fields, the demand for permanent magnet motors has increased, and the sales of permanent magnet motors worldwide have continued to grow. With the development of modernization level, the development prospect of the global permanent magnet motor industry is more optimistic.
Application market: The demand for permanent magnet motor downstream market is growing, and the application of permanent magnet motor is promising.
On January 18, 2018, in the TK887 and TK883 wells of the Northwest Oilfield, the power supply management center and the third oil production plant technicians tested the permanent magnet synchronous motor that replaced the asynchronous motor. Tests show that the power factor of the permanent magnet motor is more than 2 times higher than that of the asynchronous motor, and the operating current is reduced by nearly 50%. After calculation, only one well of TK887 can save about 10,000 degrees of electricity in one year and save nearly 10,000 yuan in electricity costs. At present, there are about 1,300 pumping wells in the Northwest Oilfield, all of which are updated with electric motors, and the annual reduction can reach more than 5 million yuan. This test provides a solid technical basis and reliable basic data for the replacement of asynchronous motors in the northwest oilfield permanent magnet synchronous motor.
The application of permanent magnet motors in oil exploration is a microcosm of the continuous expansion of its application market. The application of permanent magnet motors in the automotive field is advancing at an unprecedented speed.
In the field of new energy vehicles, permanent magnet synchronous motors are widely used. From the perspective of mature motor technology in the market, permanent magnet synchronous motors are widely used, such as Kia K5 Hybrid, Roewe E50, Tengshi, Beiqi EU260 and so on. The Tesla Model X and Model S all use asynchronous motors. From the table below, we can get a general idea of the three typical motor characteristics.
From the current technical 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 range of speeds, low cost, simple process, and reliable and durable operation. As for the impact of weight on cruising range, if the battery life mileage increases significantly in the future and the asynchronous motor volume is optimized, it will inevitably have a strong impact on the permanent magnet synchronous motor.
On January 5, 2018, China Association of Automobile Manufacturers and China Rare Earth Industry Association organized the inaugural meeting of the upstream and downstream cooperation mechanism for rare earth permanent magnet materials for new energy vehicles. The Director of the Department of Raw Materials Industry of the Ministry of Industry and Information Technology said that the drive motor is the "heart" of new energy vehicles, while the rare earth permanent magnet material is the material of choice for driving 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 a upstream and downstream cooperation mechanism is conducive to opening up the barriers between the development of new energy vehicles, drive motors and rare earth permanent magnet materials, and achieving mutual benefit and win-win in the entire industry chain. From the perspective of policy and technology, permanent magnet motors will usher in a period of development opportunities.
Under the background of continuous expansion of the downstream application market and continuous improvement of technological innovation, Forward-looking Industrial Research Institute expects that the market size of the permanent magnet motor industry will exceed 135 billion yuan in 2023, and the application prospect of permanent magnet motors is large.
