Abstract
In this work, a novel Halbach permanent magnet array with rectangle section and trapezoid section is
proposed and optimized. The analytical model of the Halbach array is established based on the surface
current method, which is numerically efficient and can be utilized to evaluate the magnetic field of the
Halbach array caused by varying magnet segment’s configurations. The fundamental component of the
magnetic flux density and the sinusoidal distortion rate are chosen as the optimization object and the
optimization is executed by the genetic algorithm in global scale. The effectiveness of the optimization
is validated by the finite element analysis in Comsol. Compared to the traditional Halbach array with
rectangle section, the magnetic field created by the proposed Halbach array in this paper owns better
performance
