Halbach Magnets
Halbach linear array:
It combines the radial and parallel arrangement of magnets to form a one-sided magnetic field (one-sided field), which is a significant feature of Halbach. This characteristic indicates that Halbach magnets have very good application value in linear motors (linear motors).
Halbach circular array:
It is generally used in brushless AC motors and magnetic couplings to enhance the unidirectional magnetic force, can obtain a nearly perfect sinusoidal magnetic force release. Because it is a unidirectional magnetic force release, non-ferromagnetic materials can be used as the central axis (such as aluminum), which can greatly reduce the overall weight and improve efficiency.
How do we assemble the Halbach array?
It should be noted that the assembly of the Halbach array is extremely difficult, specifically the following points:
-Magnets need to be assembled in a magnetized state, so we must know how to grasp the mutually repelling forces between magnets.
-The magnets in the Halbach array are easier to demagnetize.
-How to design and produce assembly fixtures? It requires a good understanding of the magnetic circuit, and years of experience in assembly of magnetic components.
-Newland Magnetics has many years of industry experience in designing and assembling various magnetic component products by itself. If you have similar problems, please contact us to discuss them.
