This study proposes a new dual‐mode flux‐switching doubly salient DC‐field (FS‐DSDC) machine for the wind power harvesting applications. The key distinction of the proposed machine is to artfully incorporate the design concepts of two machines, namely, the flux‐switching DC‐field (FSDC) and the DSDC machines together. By regulating the winding configurations, the proposed machine can behave similarly as the corresponding machines do and hence achieving the dual‐mode operations, namely, the FSDC mode and DSDC mode, to offer higher flexibility and stability for different wind situations. The proposed machine can utilise its external DC‐field winding to tune its flux density effectively, hence providing the constant‐voltage charging function at various wind speeds and loads. The corresponding performances of the proposed machine are analysed by using the finite element method and verified by experimental results.
