Analytical model of a dual‐stator spoke‐type permanent magnet synchronous machines accounting for tooth‐tips

This paper presents an analytical model of a dual‐stator spoke‐type permanent magnet (DSSTPM) synchronous machines accounting for tooth‐tips. Based on the two‐dimensional (2‐D) subdomain technique, the field domain of DSSTPM machine is divided into seven sub‐regions, that is, permanent magnet (PM), outer/inner air gaps, slots and slot openings. The magnetic field distribution and electromagnetic performance can be calculated via solving the governing functions based on boundary and interface conditions. The analytical predictions for DSSTPM machine under both open‐circuit and on‐load conditions are calculated and compared by the finite element (FE) method.
