This paper proposes a new method to find winding function for damper bars. The damper bars in a salient pole synchronous machine (SPSM) are shorted together and dissimilar currents can obviously flow in each of the shorted bars and the winding function technique seems to be unable in solving this problem. However, in this paper it will be shown that the winding function Theory can still be used. Using this winding function for the damper bars, machine inductances are computed. To demonstrate the correctness of the proposed method, the Finite Element Method (FEM) simulation has been employed.
