The principle and manufacturing process of magnetic steel

Based on the above information, it can be summarized as follows: According to the principle of electromagnetic induction, a strong current can generate a strong magnetic field. By using a strong magnetic field, ferromagnetic materials can be magnetized. Due to the different magnetization characteristics of different materials, some materials are easy to magnetize and are not easy to lose magnetism (lose magnetism), allowing them to maintain magnetism for a long time. Magnetizing this material produces a magnet. Use a magnetizer to magnetize hard magnets.According to the principle of electromagnetic induction, current can generate a magnetic field, and using a strong magnetic field to magnetize hard magnetic materials is generally referred to as the magnetic material of a magnet. In fact, there are several different things: the most common magnet, such as the magnet used in general speakers, is a ferrite magnet. They are produced by using iron scales (in the form of flakes of iron oxide

How to better maintain the service life of neodymium iron boron magnets

Nowadays, the application range of magnets in daily life is still quite common. There are many types of magnets in the market, such as strong neodymium iron boron magnets, permanent magnet ferrite, aluminum nickel cobalt magnets, and so on. Nowadays, the performance of neodymium iron boron magnets is still relatively good, and they are still a widely used magnet in practical applications.Before manufacturing magnets, there is no uniform and fixed shape of a sturdy magnet, and even when it becomes a magnet, it is not magnetic because the material of the magnet is not magnetic. The shape of a strong magnet can only be generated after artificial synthesis. For example, a square strong magnet in a strong magnet. A square magnet has a higher probability of shape, and different materials have different impacts on the daily maintenance of square magnets. In order to better protect the mechanical equipment of square strong magnets and the finished products of equal phase magnets, two points sh

Introduction to the characteristics and processing technology of magnets

Magnetic materials, as the latest result of the development of rare earth permanent magnet materials, are known as the "magnetic king" due to their excellent magnetic properties. Magnetic materials are alloys of neodymium, iron oxide, etc. Also known as magnetic steel. The advantages of high magnetic energy product and coercivity, as well as high energy density, have made permanent magnet materials widely used in modern industry and electronic technology, making it possible to miniaturize, lighten, and thin equipment such as instruments, electroacoustic motors, and magnetic separation magnetization. The advantages of it are high cost-effectiveness and good mechanical properties; The shortcomings lie in the low Curie temperature point, poor temperature characteristics, and easy pulverization and corrosion. It must be improved by adjusting its chemical composition and adopting surface treatment methods to meet the requirements of practical applications.The third-generation rare earth per

Composition of EPS system

The EPS electronic power steering system is based on the traditional mechanical steering system. According to the torque signal on the steering wheel and the driving speed signal of the car, the electronic control device is used to generate auxiliary power of corresponding size and direction from the electric motor to assist the driver in steering operations. It can easily provide different assistance effects to the electric motor at different speeds, ensuring that the car is lightweight and flexible when turning at low speeds, has sufficient road feel when turning at high speeds, and is stable and reliable.Although different cars have different structural components, the structure of the EPS system is generally the same. It is generally composed of a torque (steering) sensor, electronic control unit, electric motor, reducer, mechanical steering gear, and battery power supply.

Talking about the application of permanent magnet materials in automotive EPS

The full English name of EPS is Electronic Power Steering, which refers to the electronic power steering system. It uses the power generated by the electric motor to assist the driver in power steering. The steering system, as an important component of the entire vehicle, is one of the key systems that affect the handling stability, comfort, and driving safety of the vehicle.In the design of steering systems, in order to alleviate the contradiction between vehicle steering portability and steering sensitivity, most commercial vehicles and 50% of sedans use power steering systems. Since the 1950s, the power steering system has gone through three development stages: conventional hydraulic power steering system (HPS), electro-hydraulic power steering system (EHPS), and electric power assisted steering system (EPS), and there is a trend towards electronic and intelligent development.From a global perspective, the loading rate of automotive EPS has exceeded 50%.
