    Sintered Neodymium Radial Oriented Multipole Magnetic Ring Feature:

    Sintered radial neodymium iron boron ring magnets are oriented by radial alignment of powders. It can be straight, skew or unipole magnetized. There are two production methods – sintered powder or hot press (MQ3) method. Compared to traditional arc magnets or IPM (internal permanent magnet) assemblies, radial rings can improve motor performance and increase yields over traditional motor assembly methods. These magnets are widely used in DC brushless and servo motors for robotic and automotive applications.

    Due to the constraint of material, sintered neodymium used in motors is assembled into ring by segment magnet. China Magnets Supplier MPCO INC. can offer radially orientated Sintered NdFeB rings with a wide variety of grades and different coating options after researching continually in Sintered NdFeB material and its structure, orientation compression, magnetizing method, sintering and heat treatment process. Radially orientated sintered NdFeB ring greatly improve motor output properties, significantly reduce the motor loss at the same time.

    The radially oriented ring magnet means that the magnetization direction of the ring magnet is in a radial pattern through radial direction. Even if many sales in the magnet industry unable to distinguish radially oriented ring magnet and diametrically magnetized ring magnet until now.

    High efficiency magnetic ring is the core part of permanent magnet synchronous motors, stepping motors and DC brush-less motors, these motors are widely used in automotive, computers, electrics, communications, office and school equipments, and household products.

    For sintered rare earth magnet, the traditional method to make multi-polar magnet is often by placing arc segments magnets on a ring shape. The intricate process and uneven distribution of magnetic field strength are always restrict the development of this method. Radially Oriented NdFeB Ring Magnets

    The biggest role of radially oriented technology is helping anisotropic magnet to achieve multi-polar magnetization, and extend its application in various areas.

    The advantages of radially oriented ring magnet

    The assembling process of motor assembly will be much easier than gluing arc segments magnets on a ring, also the assembling cost.
    The assembling accuracy of radially oriented ring magnet will be much higher than traditional multi-arc assemblies, then improve the dynamic balance of the motor.
    Improve the utilization rate of raw material.
    Modify the distribution of surface magnetic field, then motor powder will increase more than 15%.
