Product Description

Rare Earth Powerful Neodymium Bar Magnets N45 Grade Multifunction​



Permanent NdFeB Neodymium magnets widely application:

NdfeB Neodymium rare earth permanent magnets are widely use in many area,Such as Motors, Sensor, Speaker, Rotors, Alarm, Microphone, Wind turbines/Wind generators, Magnetic Hooks, Magnetic Holder, Filters automoblies and so on.



Advantages Of Rare Earth Magnets

Higher unit magnetic properties than other magnet

Lower temperature coefficient of magnetic properties than ceramic but higher than SmCo type rare earth magnet

High power density

Compared with the traditional permanent magnet motor architecture, the magnetic field intensity on the other side is greatly increased due to the superposition of the parallel magnetic field and radial magnetic field after the Halbach magnetic ring decomposition, which can effectively reduce the volume of the motor and improve the power density of the motor.

Chute is no longer required for fixed rotor

In traditional permanent magnet motors, due to the inevitable harmonics of air gap magnetic field, chute is usually used to weaken the influence of air gap magnetic field. In Halbach motor, due to the high degree of sinusoidal distribution of air gap magnetic field and low harmonic content, the rotor does not need chute.
