Permanent Magnet in Automotive EPS The full English name of EPS is Electronic Power Steering, that is, electronic power steering system, which uses the power generated by the electric motor to assist the driver in power steering. As an important part of the whole vehicle, the steering system is one of the key systems that [...]
Inverter Air Conditioner: a new point of growth for permanent magnet materials Air conditioners that meet the first-class energy efficiency standard can obtain a market access pass. It is expected that inverter air conditioners will experience explosive growth and market penetration will further increase. From July 1, 2020, my country officially began to implement the [...]
Φ Magnetic Flux In the application of magnets, magnetic flux (Magnetic Flux) is an important index to measure the performance of magnets, especially in the fields of motors, audio speakers, etc. The concept of magnetic flux Assuming that in a uniform magnetic field with magnetic induction intensity B, there is a plane with area S [...]
Permanent Magnet Materials in Coreless Motors With the continuous development of science and technology, motor technology is also constantly innovating. Especially in today's industrial field, higher expectations and requirements are constantly put forward for the servo characteristics of motors, and coreless motors have emerged as the times require. Coreless motors are DC permanent magnet servo [...]
Surface Magnetism and Magnetic Flux Remanence, coercive force, intrinsic coercive force and maximum magnetic energy product are the four most common parameters to measure the performance of magnetic materials. In addition, we will often see two other parameters in finished magnets - surface magnetism and magnetic flux (also called magnetic flux). Surface magnetism The simple [...]
NdFeB chemical composition analysis (ICP atomic emission spectroscopic analysis) The chemical composition analysis of NdFeB materials generally includes: 1-Chemical composition analysis of raw materials, including the chemical composition of rare earth metal raw materials, as well as industrial pure Fe, B-Fe alloys and other metals, such as Ga, Al, Nb, Zr, etc.; 2- The chemical [...]
How to clearly describe a magnet purchase requirement How to communicate needs with magnetic material sales staff? What details must be clarified in order to obtain accurate quotations and delivery dates? If you have such doubts in the procurement of magnetic materials, then today's article must be of great help to you. It is clear [...]
NdFeB Surface Treatment - Passivation Coating The role of NdFeB permanent magnet surface protection has three aspects: 1- Improve the corrosion resistance of NdFeB, and use various surface protections to resist corrosion such as humid environments, acids, alkalis, salts and harmful gases; 2- Thoroughly clean the surface of the magnet, such as removing loose magnetic [...]
Soft Ferrites Applications Ferrites are polycrystalline oxides manufactured by ceramic technology and belong to a class of materials that exhibit the technically useful property of ferromagnetism. In a ferromagnetic material, magnetism occurs under the influence of an externally applied field. On removals of this field, material returns to its non-magnetic state. This behaviour is termed [...]
About LLC Converter Topology Power conversion is the process of converting electrical energy from one form to the other. The devices responsible for this conversion can work to convert alternating current (AC) into direct current (DC) & vice versa. They range from simple setups like a transformer to more complex conversion systems like resonant converters. [...]
Why are Ferrite Cores Used for Antenna Coils? Antennas have been used for many years to catch waves that are invisible to the naked eye. These electromagnetic waves travel around us, carrying information that’s grabbed by the antennas & used by the application it's attached to. Since all current-carrying wires around us develop their own [...]
Know About Ferrite Cable Cores As long as electronic items surround us, electromagnetic waves will be around us too. These waves are naked to the human eye and won’t affect your day-to-day activities. Born from the flow of electric current, these, however, can affect parts of devices like the power supply cable. The cable acts [...]
