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 [...]
MP Materials begins construction of magnetics plant, cements supply agreement with GM MP Materials has begun construction on its previously announced rare earth metals, alloys and magnet manufacturing facility in Fort Worth, Texas, marking a significant return to magnet manufacturing in North America. The company said that it will invest US$700 million in the next [...]
SOFT MAGNETIC POWDER VS LAMINATE MATERIAL for Electric Motor Efficiency Which is easier to trust -- a 1,300-component assembly with shaky performance, or a 10-component one with reliable data? Many manufacturers have worked with the standard, stamped lamination steels for decades. Engineers know the obstacles associated with them, and they accept them as law. But [...]
Sintered NdFeB Magnets Composition and Microstructure Sintered NdFeB Magnets Composition Sintered NdFeB magnet contains three essential elements: rare earth neodymium, iron and boron. Nd atoms, coupling with ferromagnetic Fe atoms, help the magnet obtain high remanence Br and maximum energy product (BH)max, which makes it extraordinary compared with other permanent magnets. Although B element has [...]

The Bonded Magnet market has grown significantly as a result of factors such as the expansion of [...]
Properties of hot-pressed and hot-deformed NdFeB magnets Hot-pressed and hot-deformed NdFeB magnets were successfully researched and developed almost simultaneously with sintered NdFeB magnets. In 1985, the General Motors Corporation (GM) Research Center of the United States reported that using hot pressing technology to press the quenched NdFeB magnetic powder in an argon environment at 700 [...]
