| Abstract: | D ouble stator flux reversal machine(DS-FRM) is a kind of novel permanent magnet machines, based on magnetic modulation principle, and it is becoming a promising candidate for low-speed high-torque applications such as ship propulsion and wind power generation. Compared with traditional flux reversal machines(FRM), The topology of DS-FRM can solve the confliction between permanent magnets and windings of single stator FRM, but its boundary conditions become more complex. The accurate magnetic calculation of DS-FRM always plays an important role in design and optimization of its electrical performances, While to establish an accurate mathematical model is the key to solve the magnetic field problem . However, the boundary conditions of DS-FRM are complicated, conformal transformation method for solving the cogging effect of conventional single stator motor is no longer applicable. In this paper, the accurate subdomain model method is adopted to investigate the DS-FRM with complex boundary, the two-dimensional vector Laplace equation was established in different air gap subdomains, and the two-dimensional vector Poisson equation was established in the permanent magnet domain, and different equations in different subdomains are solved by the separation of variables method. Based on analytical solutions, the distribution of air gap magnetic density and cogging torque are solved, and the results are validated by finite element method. |
