Halbach Assemblies | Magnetic Assemblies | Halbach Array |Halbach permanent magnet
Short Description:
The principle of Halbach array is to use a special arrangement of magnet units to enhance the field strength in the unit direction.
Specifically, in the Halbach array, the magnetization direction of the magnets is arranged according to a certain law, so that the magnetic field on one side is significantly enhanced, while the magnetic field on the other side is weakened or even close to zero. This arrangement can improve the utilization efficiency of the magnetic field, and is widely used in the fields of motor and magnetic levitation.
The magnetization vector of the ideal linear Halbach array is continuously changed according to the sinusoidal curve, so one side of its strong magnetic field is distributed according to the law of sine, and the other side is zero magnetic field. Linear Halbach arrays are mainly used in linear motors, such as maglev trains, one of the principles is the suspension force generated by the interaction of the moving magnet and the magnetic field generated by the induction current in the conductor, this magnet usually has light weight, strong magnetic field, high reliability requirements.
The cylindrical Halbach array can be viewed as a circular shape formed by connecting the straight Halbach array end to end. The same as the linear Halbach array is that the magnetization direction of the permanent magnet is difficult to change continuously along the circumference, so in actual operation, the cylinder is also divided into M sector magnets of the same size.
1.Directional magnetic field enhancement: OurHalbach arrays are capable of generating extremely strong magnetic fields in specific directions, significantly increasing the strength of the magnetic field compared to conventional magnetic arrays.
2.Efficient magnetic field utilization: Through a carefully designed magnet layout, the Halbach array is able to concentrate the magnetic field in a specific area, reducing the waste and dissipation of the magnetic field.
3.Precise magnetic field control：By adjusting the arrangement and Angle of the magnets, the Halbach array can achieve flexible adjustment of the magnetic field direction to achieve more accurate magnetic field control, and we can control the magnetic declinationwithin 3°.
4.Magnetic field direction Angle: Advanced manufacturing processes and equipment ensure the manufacturing precision and quality of Halbach arrays. The precise magnet processing and assembly process ensures the uniformity and stability of the magnetic field, and reduces the fluctuation and error of the magnetic field.
