Low Eddy Current Losses Segment SmCo Laminated Magnet Item No. MPCO-LAMS series

The magnet made by segmentation technology can be called laminated magnet, layered magnet, split magnet and segmented magnet. For magnet segmentation technology, the whole magnet will be segmented into several pieces, then processed into specific shape and dimension after glued together by special isolation glue.

What is the Advantages of Laminated Magnet?

According to many simulation cases and actual products, the magnet segmentation technique has excellent performance to prevent the eddy current. With the increase of segment, the eddy current losses of permanent magnet significantly decreased. Magnet segmentation technique has been already applied in the NdFeB and SmCo magnet.

Samarium cobalt is a rare earth material made by a powder metallurgical process. Manufactured using binders such as epoxy, samarium cobalt magnets are inherently very brittle. Users are discouraged from grinding material because the dry remnants are a fire hazard. Some of the advantages of using samarium cobalt is that it provides excellent temperature stability and as well as excellent corrosion resistance. Because of this, typically coating or plating is not required. Samarium cobalt is excellent for operating in harsh environments where it will be exposed to the elements as well as high operating temperatures.

How to reduce eddy current losses of rare earth magnet?

How to reduce eddy current losses of rare earth magnet?

The eddy current loss of rare earth magnet can be reduced by many ways, among them, the material science researchers have proposed to prepare the high-resistivity magnet, such as:

a. Bonded magnet.

b. High-resistivity sintered magnet.

What is Eddy Current Losses of laminated magnet

The consumption of motor is the greatest among the rotating machinery. The eddy current losses are one of the worst enemies to high-speed rare earth permanent magnet motor. The eddy current will give rise to the temperature of the rare earth permanent magnet, then the magnet will be demagnetized, therefore influence the work efficiency of the motor. As the metallic material, the rare earth permanent magnet has lower electrical resistance, and it also become the direct source of eddy current losses.

What is Skin Effect

The internal of metal with good conductivity will generate the induced electromotive force under the external changing magnetic field, and formed the eddy current inside the metal. The Joule heating effect of the induced eddy current lead to the above-mentioned eddy current losses. Actually, the eddy current concentrates mainly on the surface layer of the conductor. This phenomenon is known as the skin effect, and the basic reason is that the changing electromagnetic field generates an opposite vortex electric field inside the metallic conductor. The skin depth δ can be described as below relation: ISO/IATF Certificated High Temperature SmCo Laminated Magnet Where μ is the permeability of conductor; ρ is the electrical resistance; ω is the angular frequency of alternating magnetic field, ω=2πf.The higher rotation speed, high permeability and low electrical resistance will cause lower skin depth and high losses.

We can also provide magnetic assembly,even the complete motor robot. Segmented Lamination Magnet

Bonded Injection Magnets Powder NdFeB, SmCo, Ferrite Shape Ring, Disc Magnetization Direction Thickness or Custom request Plating Epoxy Maximum Operating Temperature 120-180°C Density (g/cm3) 5.6-6.4

Key Benefits

High magnetic performance. Maximum Energy Product(BHmax) can reach 18MGOe; Extremely tight tolerances. Suitable for various shapes or over components in assembly; Stable working temperature. The most high working temperature can be up to 180°C; Good corrosion resistance in water and industrial solvents; Flexible multipole mumagnetized in any direction; High efficient magnets compared to other magnets.

Bonded magnets, also called compression bonded magnets, are an excellent choice over other magnet types. They are suitable for the application which request high magnetic field strength, general mechanical strength, and simple compression shape. Bonded magnets are manufactured by molding compression of the compound alloy powder (Neodymium or SmCo) with resin. The resin is further processed to form magnets and resistant to normal industrial solvent and automotive fluids. Since no magnetic field is applied during the compression, the finished product can be magnetized in any direction. The normal application temperatures range from below -40°C to above 165°C.

Injection magnets, also called injection molded magnets, are produced by an injection process of pre-mixed magnetic powder or mixed other composite material. Magnetic powders include Ferrite, Neodymium, and SmCo. Binder types include Nylon 6 and 12, PPS, and Polyamide, which produces an accurate and homogeneous magnetic part. Through this process magnets can be directly molded into various shapes (thin-wall ring, rods, slice, holes and pins, etc.) or over the components (shafts, cams, inserts and the like eliminating some steps) in assembly, with extremely tight tolerances and a broad range of magnetic properties and characteristics. Injection Molded magnets have good corrosion resistance in water and industrial solvents. The binders and magnetic alloys are capable of a wide range of application temperatures from below -40°C to above 180°C. Bonded Ring & Disc Magnets
