Permanent Magnet Materials in Coreless Motors
5 mm Disc Magnet With the continuous development of science and technology, motor technology is also constantly innovating. Especially nowadays, the industrial field has continuously put forward higher expectations and requirements for the servo characteristics of motors, and hollow cup motors have come into being. Hollow cup motors are DC permanent 5 mm disc magnet […]
Performance of NdFeB Magnets
Permanent NdFeB Magnet The permanent ndfeb magnet is made into a certain shape. For example, if the magnetization curve in the open circuit state is measured along the x, y, and z directions of the magnet, it can be found that along the x direction, only a lower magnetic field (H1) is needed to magnetize […]
Magnetic field intensity H and magnetic induction intensity B, magnetization intensity M and magnetic polarization intensity J
N35 Permanent Magnet The basic concepts of magnetism H, B, M, and J are related but easy to confuse. H is the magnetic field excited by the current, and B is the total magnetic field felt by the material. M is the magnetization intensity of the material, and J is the magnetic polarization intensity. The […]
Classification of Magnetism and Magnetic Materials
Neodymium Plate Magnet When it comes to magnetic materials, we have to talk about “magnetism” first. Experiments show that any substance can be magnetized to a greater or lesser extent in an external magnetic field, but the degree of magnetization is different. According to the characteristics of the substance in the external magnetic field, the […]
Principle and technology of relative detection of magnetic properties of NdFeB products
Cheap N52 Magnets The technical magnetic parameters of sintered NdFeB permanent magnet materials should be given, including remanence Br, magnetic coercivity Hcb, intrinsic coercivity Hcj, magnetic energy product (BH)m, demagnetization curve squareness and B-H demagnetization curve recovery magnetic material rate μrec, etc. Today we will focus on the principle and technology of relative detection (or […]
Pot Magnet
Instant Pot Magnet A Instant Pot Magnet, also known as a cup magnet or a channel magnet, is a type of magnet that is encased in a metal pot or cup. This design amplifies its magnetic force by directing the magnetic field through the front of the pot, making it much stronger in the direction […]
Remanence/coercivity/reversible temperature coefficient
Gig Ndfeb Magnet Big ndfeb magnet are generally used as magnetic field sources to provide a constant magnetic field within a certain space. For some precision instruments and magnetic devices, the stability of the big ndfeb magnet’s magnetic field is crucial, as it directly affects the accuracy and reliability of the instrument. 1. Stability of […]
Principle and technology of relative detection of magnetic properties of NdFeB products
Small Disc Neodymium Magnet Sintered NdFeB small disc neodymium magnet magnet products should provide the technical magnetic parameters of the product, including remanence Br, magnetic coercivity Hcb, intrinsic coercivity Hcj, magnetic energy product (BH)m, demagnetization curve squareness and B-H demagnetization curve recovery magnetic material rate μrec, etc. In 1992, the State Administration of Quality Supervision, […]
Samarium Cobalt Permanent Magnets and Their Properties
Smco Arc Magnet Samarium cobalt permanent magnets are mainly composed of metal samarium (Sm), metal cobalt (Co), copper (Cu), iron (Fe), zirconium (Zr) and other elements. They are divided into 1:5 type and 2:17 type in terms of structure, and belong to the first and second generation rare earth permanent smco arc magnet materials. smco […]
