Abstract :
Halbach array is new permanent structure. It was proposed by physicist Dr. K. Halbach of the U.S. Lawrence Berkeley National Laboratory. This paper proposes an improved magnet structure of Halbach array. By simulation of finite element software-Ansoft´s Maxwell, the results show that improved magnet structure can effectively improve the uniformity of the magnetic field within the array comparing with one-on-pole Halbach magnet array Composed by fan-based units.
