The important role of permanent magnet motor in various application fields

1. Energy saving rare earth permanent magnet motors are mainly used for consumption, such as rare earth permanent magnet synchronous motors used in textile, chemical fiber industry, petroleum and mining, rare earth permanent magnet synchronous motors used in coal mine transportation machinery, and rare earth permanent magnet synchronous motors drive various pumps and fans.

2. Various rare earth permanent magnet motors are used by various types of vehicles (cars, motorcycles, trains). According to statistics, about 70% of rare earth permanent magnet motors are used in automobiles. For luxury cars, there are more than 70 sets of motors for various applications. Due to the different requirements of various automotive motors, the selection of permanent magnet materials is also different. Motor magnets are used for air conditioners, fans and power windows. In terms of price, the advantage of ferrite will continue in the future. SM co sintered magnets are still used in ignition coils, drives, and sensors. In addition, auto parts can not be ignored for electric vehicles, such as environmental protection (EV) and hybrid electric vehicle (HEV).

3. The AC servo system of rare earth permanent magnet motor is an electronic, high-performance, mechatronic mechanical speed regulation system. The system is an autonomous permanent magnet synchronous motor. The system is used to develop flexible manufacturing technology of CNC machine tools; It is also used in electric vehicles to replace traditional thermal vehicles without vehicle emissions. Rare earth permanent magnet motor is a promising high-tech industry.

4. The new fields are mainly the matching of the new low-power rare earth permanent magnet synchronous motor frequency conversion and speed regulation system for new air conditioners and refrigerators, various radio accessories for rare earth permanent magnet DC micro motors, and rare earth permanent magnet brushless DC motors are instruments with different powers. There is also a great demand for this kind of motor.

5. The application of rare earth permanent magnet materials in the aerospace field has unique advantages, which is very suitable for the application of aeroengines. Although rare earth permanent magnet motors have some applications in the air (such as generator voltage, short-circuit protection, etc.), it is agreed at home and abroad that rare earth permanent magnet motors are an important development direction of the new generation of aeroengines.
