The most important thing is that the application of rare earth permanent magnet synchronous motor is very wide, and its appearance has attracted the attention of all walks of life. Next, this paper will introduce the application field of rare earth permanent magnet synchronous motor, hope to help you!

The application fields are as follows:

1. Energy saving type rare earth permanent magnet synchronous motor aims at consumption, such as textile, chemical fiber, petroleum, mining rare earth permanent magnet synchronous motor, coal mine transport machinery, etc. rare earth permanent magnet synchronous motor drives various pumps and fans.

2. All kinds of rare earth permanent magnet synchronous motors are used by various types of vehicles (cars, motorcycles, trains). Rare earth permanent magnet is the largest shopping mall. According to statistics, about 70% of rare earth permanent magnet synchronous motors are used in automobiles. There are more than 70 luxury cars for various purposes. Due to the different requirements of various automotive motors, the selection of permanent magnet materials is not the same. Motor magnets are used in air conditioners, fans and power windows. From the price point of view, ferrite will continue to be an advantage in the future. The combustion coil, driving device and sensor are still made of SM co sintered magnets. In addition, automotive parts are also electric vehicles that can not be ignored, as an environmental protection (EV) and hybrid electric vehicle (HEV).

3. Rare earth permanent magnet synchronous motor AC servo system is a set of electronic, high-function, mechatronics speed control system. The system is the main body of automatic control of permanent magnet synchronous motor. The system can be used in the development of CNC machine tools, flexible manufacturing technology, electric cars instead of traditional thermal power vehicles, and the free emission of automobile exhaust. Rare earth permanent magnet synchronous motor is a high-tech industry with broad development prospects.

4. The new field is mainly for the support of frequency conversion speed regulation system of small power rare earth permanent magnet synchronous motor of new air harmony refrigerator, and is used for wireless electric tools of various rare earth permanent magnet DC micro motors. Rare earth permanent magnet brushless DC motor is an instrument with different power. This kind of motor is also in great demand.

5. Rare earth permanent magnet materials have advantages in the field of aerospace and are very suitable for Aeroengines. Although there are some applications of rare earth permanent magnet in the air (such as generator voltage, short circuit protection, etc.), experts at home and abroad agree that rare earth permanent magnet is also an important development direction of the new generation of aero-engine.
