Abstract The mutual inductance between adjacent armature windings of the multi-tooth switched flux permanent magnet memory machine (multi-tooth SFPMMM) is large, which will produce a large error if the mutual inductance is ignored in the optimal design. To improve the accuracy of optimization, the equivalent magnetic circuit model (EMCM) considering the mutual inductance and the end leakage was proposed in the paper. And an equivalent model considering the mutual inductance between two adjacent phases of the multi-tooth SFPMMM was established. Finally, the results of finite element analysis and the experimental prototype were used for verification. Compared with the EMCM without considering the mutual inductance, the experimental results show that the calculation accuracy of the back electromotive force (back-EMF) in no-load condition is improved by 15.3% using the proposed model.
