The Halbach array is an important approach to enhance the levitation performance of permanent magnetic guideway(PMG)in terms of its unilateral magnetic focusing property.For the complex magnetic field distribution behavior of Halbach-type PMG,a simple three-dimensional magnetic field analytical method is proposed.First,with the assumption of uniform magnetization,an analytical model of a single magnet is developed according to the Biot-Saval law.Subsequently,the three-dimensional magnetic field analytical model of the complete orbit is obtained based on the magnetic density accumulation.Finally,the reliability and accuracy of the proposed model are verified through comparison of measured values,analytical and finite element solutions.Our results will provide a significant reference for the design and optimization of PMG.
