Product Description

Factory Direct Sell Customized Halbach Array Strong Magnetic Coupling

Brushless AC Motor Magnetic Assembly

Introduction：

1. Magnetic coupling is a coupling that transmits torque from a shaft, but uses a magnetic field instead of a physical mechanical connection.

2. Magnetic couplers are most commonly used in liquid pumps and propeller systems because a static physical barrier can be placed between the two shafts to separate the fluid from the motor running in air.

3. Magnetic coupling precludes the use of a shaft seal, which will eventually wear out and will not fail due to the two surfaces sliding against each other

4.When using physical shaft couplings, magnetic couplings are also used in systems that are easy to maintain and often require precise alignment because they allow for greater off-axis errors between the motor and driven shaft.

How does the magnetic coupling work?

What is the Halbach array?

Halbach Array is a new type of permanent magnet arrangement. The permanent magnets with different magnetization directions are arranged in a certain order, so that the magnetic field on one side of the array is significantly enhanced, while the other side is significantly weakened. It's main forms are linear array and circular array.

Name	Halbach Array, a new permanent magnet arrangement
Material	Magnet: sintered neodymium magnet Hardware: 20 # steel, martensitic stainless steel
Advantage	High power density Fixed rotor no longer, requires chute Rotor can use non-core, material High permanent magnet, utilization Can use, centralized winding
Application	Brushless AC motor, voice coil, Torsion pendulum magnet of particle accelerator, free electron laser,Permanent magnetic coupling and high magnetic field cylinder

Halbach linear array:

The Halbach linear array 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:

The Halbach circular array is generally used in brushless AC motors and magnetic couplings to enhance the unidirectional magnetic force, and 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.
