N2 - A 100kW level High-Speed Permanent Magnetic Generator (HSPMG) used for distributed generation systems is electro-thermal analyzed with coupling in this paper. Its electromagnetic performances is analyzed by using time step FEA, from which the electromagnetic performance and loss distributions in machine under rated operating are determined. Based on the determination of associated heat transfer conditions, the whole region two-dimensional thermal field is calculated. Then, thermal performance of HSPMG with stator oil separators made of nano AIN and ceramic material are studied, and also the cooling structure without oil separator is analyzed. Meanwhile, thermal affection of the insertion of ceramic gradient thermal barrier coatings between rotor magnets and sleeve is researched, and temperature distributions of machines with different thickness thermal barrier coatings are studied. Some conclusions about influences of material and structure on HSPMG thermal performance are obtained, which may provide useful reference for the design and research of HSPMG.
