Summary:This paper presents a thermal study of a novel highspeed dual-stator 6/4 FSPM machine. The novel dual-stator 6/4 FSPM machine is developed to provide a viable solution for low pole FSPM machines at high speed conditions. However, the highspeed machine generates losses and the heat dissipation is crucial in keeping the performance of the electric machine. In this paper, the thermal aspects of the design are investigated. Critical thermal model issue such as anisotropic thermal conductivity, contact thermal resistance are discussed. The lumped-parameter thermal network (LPTN) model of this machine is first developed for preliminary studies. Then finite element analysis (FEA) is performed to obtain more accurate results. With different cooling methods applied, FEA results verified that this proposed machine maintains a safe temperature range under the rated condition. The analytical method discussed in this paper is applicable to other types of FSPM machine where the main heat source is located in the stator.
