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.
