Halbach arrays are a precise arrangement of permanent magnets that directs the magnetic field in a specific area while cancelling the magnetic field to near zero on the other side. We can make halbach arrays and halbach assemblies per customer requirements, but have the below assemblies in stock. If you require a specific size that is not available on hsmagnets.com, please contact us for a custom magnet quote.
With respect to the conventional motor, Halbach motors are the following advantages
1 Compared with the traditional structure of the permanent magnet motor, the mutuals uper position radial magnetic field strength on the other side so greatly enhance this would effectively reduce the volume of the motor,to enhance the power of the motor density.
2 rotor is no longer needed chute
In conventional permanent magnet motor, due to the inevitable presence of the air gap magnetic field harmonics, in general, based on the rotor chute weaken its impact. In Halbach motor, because the air gap magnetic field distribution of the higher degree sinusoidal harmonic content is small, so the rotor without a chute.
3 rotor can be non-core material
Halbach magnet because unilateral field shielding effect resulting from the distribution of the magnetic material for the rotor is no longer necessary to provide access, not only to provide a larger selection of materials selected from the rotor, and the system may have a lower moment of
inertia and less good performance should be attached quickly.
4 high efficiency permanent magnet
Due to the results of Halbach magnetized magnets, which leads to higher operating point of the permanent magnet, generally more than 0.9, to improve the utilization of the permanent magnet. super strong ndfeb halbach magnets, cylindrical halbach array magnet
5 can use a centralized winding
Permanent magnet motors are often used in traditional distributed windings to weaken the influence of harmonic MMFs. In Halbach motor because of its high degree of sinusoidal magnetic field distribution of the harmonic magnetic field has little effect, it can be centralized winding.

Motor using Halbach magnet arrangement can reduce the torque ripple of the motor, thus greatly reducing the requirement for the motor bearings.
