Application fields of earth permanent magnet motors

We learned about the operating principle of the earth permanent magnet motor last time, and we can see that its principle is somewhat complicated. Importantly, earth permanent magnet motors have a wide range of applications, and their emergence has attracted attention from all walks of life. Next, this article will introduce the application fields of earth permanent magnet motors. I hope it will be helpful to everyone!

Application areas are as follows:

1. The main goal of energy-saving earth permanent magnet motors is consumption, such as earth permanent magnet synchronous motors in the textile and chemical fiber industries, petroleum, mining, and earth permanent magnet synchronous motors used to transport machinery in coal mines. Rare earth permanent magnet synchronous motors drive various pumps and fans. .

2. Various earth permanent magnet motors are used in various types of vehicles (cars, motorcycles, trains), and earth permanent magnets are the largest market. According to statistics, about 70% of earth permanent magnet motors are used in vehicles. Luxury cars have more than 70 sets of motors for various uses. Because the requirements of various car motors are different, the selection of permanent magnet materials is different. Motor magnets are used in air conditioners, fans, and electric windows. From a price point of view, ferrite will continue to have the advantage in the future. Ignition coils, driving devices, and sensors still use Sm-Co sintered magnets. In addition, car parts cannot be ignored for electric cars, as an environmentally friendly (EV) and hybrid electric car (HEV).

3. Rare earth permanent magnet motor AC servo system is a set of electromechanical integration machinery with electronic, high-performance, speed control system. The system is a self-controlled permanent magnet synchronous motor body. The system is used in the development of CNC machine tools, flexible manufacturing technology; and is also used in electric cars, instead of traditional thermodynamic cars, to make vehicle emissions free. Rare earth permanent magnet motor is a promising high-tech industry.

4. The new field is mainly to support the low-power earth permanent magnet synchronous motor frequency conversion speed regulation system of the new air-conditioning refrigerator, wireless electric gadgets for various earth permanent magnet DC micromotors, earth permanent magnet brushless DC Electric motors are instruments with different powers. There is also a huge demand for such motors.

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