Bar Shape Industrial Neodymium Magnets Composite NdFeB Zinc Coating
Rare earth Neodymium magnet (NdFeB) is a high performance permanent
magnet, which is produced by Neodymium Iron, Boron and some other
rare earth elements, as the strongest permanent magnets discovered
up to now, is preferred by permanent magnetic devices, due to its
highly cost-effective performance based on rich rare-earth
resources, manufacture in large scale and technology development.
it has a wide variety of applications on the motors, generators and
couplings due to its high energy and reasonable price.

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.
