Sintered Radially N52 Neodymium Arc Magnets NiCuNi Coating
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.
