无轴承交替极永磁电机空载气隙磁场全局解析模型
Exact Analytical Model for the No-Load Air-Gap Magnetic Field Calculation in Consequent-Pole Permanent Magnet Bearingless Motor
摘要
Abstract
Abstract The exact analytical model of the consequent-pole permanent magnet rotor is established for the no-load air-gap magnetic field calculation in consequent-pole permanent magnet bearingless motor. The solution region is divided into air-gap domain, permanent magnet domains and slot domains. Laplace equations or Poisson equations are solved based on the boundary condition between two adjacent sub-domains, where the air-gap flux density expressions are obtained by the use of magnetic vector potential. Comparing the analytical results of the air-gap flux density and the back-electromotive force with the finite element analytical results, the correctness and effectiveness of the exact analytical model is verified.关键词
