Abstract
A quasi-3-dimensional analytical no-load magnetic model for axial flux permanent magnet synchronous machines (AFPMSM) is proposed which can be generalized to different types of regular AFPMSMs. Magnetic flux density is obtained all over the nonferrous parts of the machine using the subdomain technique for a surface-mounted slotted AFPMSM. The cogging torque is also analytically calculated based on the Maxwell stress tensor. The results of the proposed method are compared with those of the finite element method, and an eligible compromise is observed.
