Permanent magnet synchronous motors are widely used in pure electric and hybrid passenger cars. The high-performance neodymium iron boron magnetic material used in permanent magnet synchronous motors is about 1.8 kilograms. Considering the 60% consumption from raw materials to finished products, this part reaches 3 kilograms. In addition, the usage of EPS and other components reaches about 0.4 kilograms. Therefore, the usage of pure electric bicycles is about 3.4 kilograms, and the usage of hybrid bicycles is about 2.2 kilograms. Given the high energy conversion efficiency and low energy consumption of permanent magnet synchronous motors, the volume of permanent magnet synchronous motors is smaller and the efficiency is higher at the same power. It is expected that more electric vehicle models will use permanent magnet synchronous motors in the future, coupled with more vehicle models equipped with dual motor structures. There is room for further improvement in the single vehicle usage of high-performance neodymium iron boron in electric vehicles.

Neodymium iron boron permanent magnet is an energy storage material that can generate a constant magnetic field in space. Due to its extremely high coercivity and magnetic energy product, especially its excellent performance compared to other permanent magnets in environments ranging from 20 ℃ to 150 ℃, neodymium iron boron permanent magnet motors are widely used in fields such as CNC machine tools, industrial electrical automation, automatic production lines, industrial robots, and various military and civilian equipment due to their physical principle of electrical mechanical energy conversion.

Neodymium iron boron permanent magnet motors are applied in the field of transportation. As a green transportation tool in the 21st century, electric vehicles are widely valued in various countries. The main driving motors for electric vehicles are high-power permanent magnet brushless DC motors, permanent magnet synchronous motors, switched reluctance motors, etc. The development trend of these types of motors is high efficiency, high output, and intelligence. Neodymium iron boron permanent magnet motors are applied in the household appliance industry, and household appliances driven by high-efficiency permanent magnet brushless DC motors represent the direction of development in the household appliance industry.
