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 [...]
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 [...]
Sintered NdFeB Magnet Coating Type NdFeB permanent magnet has extremely high properties (high residual induction, coercive force and energy product) with really competitive price. It can be machined into all kinds of shapes easily and used in many fundamental fields directly, such as new energy, vehicles, electron & electroacoustic, energy saving household appliances, industrial motor, [...]
Parylene Coating Magnet Excellent Lots of companies want to buy neodymium magnet which with Parylene coating. Even that is expensive than Ni coating and Zn coating.People still want to buy. Why? Because Parylene is a new conformal coating material developed and applied by UnionCarbide Co. in the United States in the mid-1960s. It is a [...]
Parylene Coated Magnets What is Parylene coating? Parylene is the common name of Poly-para-xylylene, and it was prepared by the researcher in University of Manchester in 1947. The parylene first applied to U.S military and aerospace industry after Union Carbide prepared parylene thin film by the deposition process. Nowadays, parylene coating are widely used in [...]
