The Halbach array is named after its creator Klaus Halbach, a physicist in the engineering department at Berkley Labs. The array's original purpose was to aid in the beam focusing process in particle accelerators. A halbach array is an arrangement of magnets designed to enhance the magnetic flux in a certain domain.
With the exception of its two ends, a linear array of permanent magnets is intended to produce a flux field on one side and nearly cancel it on the other. The magnetization pattern is indicated by the arrows and the flux field.
A typical arrangement in Halbach array is that the magnets are oriented to enhance the field on the top of the disc and cancel it below the disc, so as to provide a net axial flux field.
Below is the cross-sectional view of a dipole constructed from a Halbach array. It also shows the directions of magnetization of the permanent magnets that make up the array. The design produces a net uniform field oriented vertically inside the array as well as a nearly full cancellation of the field outside the array. Electric motors with excellent performance and efficiency were quickly created using the Halbach arrays for a variety of applications. Gallo has created a typical axial field brushless DC motor with a permanent magnet disc. Thompson has established analytical formulas for the flux field solutions for an axial Halbach array of permanent magnets.
The electromagnetic performance of a brushless machine with a Halbach array of permanent magnets needs to be predicted and optimized using a straightforward and precise analytical model, together with a physical understanding of the relationship between parameters and performance. In order to reliably forecast the average output torque for a variety of input currents, an analytical model for the field distributions generated by a Halbach array of permanent magnets must be created. Following the interaction of electrical currents and magnetic fields, all motors produce a torque. The "Lorentz force" refers to the force acting on a charged particle in an electromagnetic field.
The introduction of a magnetic field to a current-carrying conductor of limited length produces a net force because current flow in a conductor is caused by the continuous motion of electrical charge. A net torque is produced by arranging two conductors so that their respective forces are directed in opposite directions yet are spaced apart. The armature rotates as a result of the torque. Lenz's law, according to which the motion of the armature is constantly opposed by the induced EMF, is another crucial law in regard to electric motors. As a result, the electromagnetic field and the rotation of the armature are the sources of back-EMF. As a result, the magnetic field's strength and variability are crucial factors in determining how well a motor will function.
