Ferrite Magnets NMF^™

This magnet has a high performance vs. cost and is mainly composed of iron oxide.
In addition to providing the highest class of high-performance magnets backed by our strong research and development capabilities, we also offer products unique to Proterial, such as ring shapes. They are used in a variety of applications such as automobiles and home appliances, and in recent years, studies are underway to apply them to applications where neodymium magnets have been used in the past.

We propose a method to use materials tailored to your company.

Anisotropic ring magnet

These unique magnets, realized through our advanced product design and production technologies, are mainly polar anisotropic products. Resin injection molding can be applied to attach the magnet to a rotor shaft.

Features

1The cylindrical shape easily ensures dimensional accuracy of the outer diameter facing the stator.
2Variations in magnetic flux density distribution between poles are easily reduced because the rotor can be composed of a single magnet.
3Ease of magnet assembly via resin molding to a shaft contributes to reduction of assembly labor.
4Since the amount of magnetic flux leakage from the inner diameter is sufficiently small, non-ferromagnetic materials, such as resin, can be applied to assemble to rotor components.

As this is a uniquely oriented magnet, please contact us for details on magnetic properties.

Main Applications

1On-board (DCT (dual clutch transmission), EGR (exhaust gas recirculation), PSD (power slide door), water pump, etc.)
2Appliances (water pumps, fan motors, etc.)
