Flux-switching motors (FSM) are competitive candidates for in-wheel traction systems. However, the analysis of FSMs presents\r\ndifficulty due to their complex structure and heavy magnetic saturation. This paper presents a methodology to rapidly construct,\r\nadapt, and solve a variable magnetic equivalent circuit of 12-stator-slot 10-rotor-tooth (12/10) FSMs. Following this methodology,\r\na global MEC model is constructed and used to investigate correlations between the radial dimensions and the open-circuit phase\r\nflux linkage of the 12/10 FSM. The constructed MEC model is validated with finite element analysis and thus proved to be able to\r\nassist designers with the preliminary design of flux-switching motors for different in-wheel traction systems.
