Magnet has extensive and important applications in the field of new energy, and its application potential is huge. The following are some specific aspects:
Magnet in New energy vehicle field
- Drive motor: Permanent magnet synchronous motor is the mainstream type of drive motor for new energy vehicles, and magnet is the key material of permanent magnet synchronous motor. High-performance NdFeB magnet can provide a strong magnetic field, so that the motor has the advantages of high efficiency, high torque density, small size and light weight, thereby improving the power performance and cruising range of new energy vehicles.
- Electric power steering system (EPS): EPS system requires high-precision and high-reliability motors to provide auxiliary steering force, and magnet plays an important role in it. It can make EPS motors more compact and efficient, and improve the accuracy and comfort of steering.
- Electric brake system: The motor in the electronic brake system also needs magnetic steel to achieve fast and reliable braking. Magnet in new energy application helps to improve the response speed and braking force of the brake system and enhance the safety of the car.
Magnet in Wind power generation field
- Permanent magnet direct drive and semi-direct drive fans: Magnet is a key material for the production of permanent magnet direct drive and semi-direct drive fans. Compared with doubly-fed asynchronous wind turbines, permanent magnet direct-drive and semi-direct-drive wind turbines have the advantages of simple structure, low operation and maintenance costs, long service life, good grid-connected performance, high power generation efficiency, and better adaptability to low wind speed environments, so their market share is increasing.
- Converter: The converter in wind power generation requires the use of magnet to manufacture magnetic components, such as inductors and transformers. These magnetic components are crucial to the stable operation and power conversion efficiency of the converter.
Magnet in Photovoltaic power generation field
- Inverter: The inverter is a key device that converts the direct current generated by solar cells into alternating current. The magnetic components such as inductors and transformers require the use of magnetic steel. High-performance magnetic steel can improve the efficiency and power density of the inverter, reduce losses, and thus improve the overall performance of the photovoltaic power generation system.
- Energy storage system: In the energy storage system of photovoltaic power generation, magnet in new energy application is also very important. For example, in the battery management system (BMS), magnet can be used to manufacture current sensors and position sensors to achieve accurate monitoring and control of the battery status.
Magnet in other new energy fields
- Hydrogen fuel cell vehicles: The fuel cells in hydrogen fuel cell vehicles require the use of magnetic steel to manufacture key components such as gas diffusion layers and bipolar plates. Magnet in new energy application can improve the performance and efficiency of fuel cells and promote the development of hydrogen fuel cell vehicles.
- New energy ships: The propulsion system and power system of new energy ships also require the use of magnetic steel. For example, permanent magnet motors can be used for ship propulsion to improve the energy efficiency and operation efficiency of ships.
