Using AI to optimize magnet and improve performance of motor magnet Research and development aimed at improving the performance of motor magnets is currently gaining momentum. This is because motors used in electric vehicles (EVs), which are increasingly in demand, are also urgently required to improve performance under the trend of decarbonization on a global [...]
Rare earth permanent magnets are basically used in almost high-tech industries Rare earth permanent magnet (the core product is NdFeB) is the most common rare earth material, which consumes about 57% of the total amount of rare earth, and has high added value. More than 85% of the output value of rare earth materials is [...]
The application of NdFeB rare earth permanent magnet Neodymium iron boron magnets (NdFeB) are one of the strongest rare earth permanent magnet types available, and their (BH)max is much larger than that of samarium cobalt magnets. Neodymium iron boron magnets have excellent properties, so they are often the magnet of choice for many applications across [...]
The compressor permanent magnet of inverter air conditioner The compressor of the inverter air conditioner is a permanent magnet material The compressor of the inverter air conditioner is an important downstream of the permanent magnet material. At present, the magnets used in the air conditioner compressor are divided into two types: ferrite permanent magnet material [...]
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 [...]
