This paper presents a new analytical method for leakage inductance calculation of transverse flux permanent magnet machines. In this method, leakage flux paths are predicted base on the finite element results, and then all paths would be modeled by flux tubes. Finally, the inductance of the machine would be obtained by calculation of the permeance of flux tubes. The validity of the proposed model is verified by comparing the Finite Element results with the results obtained from the proposed approach. Comparing the results shows that the proposed model is able to accurately estimate the leakage inductance of the machine with an average error less than 9%.
