This paper enumerates various stator and rotor structures and materials of the HSPMM in literature. Then different losses in the HSPMM are summarized in aspects of (high speed stator iron loss, copper loss, rotor eddy current loss and air friction loss. Various motor temperature rise calculation methods and permanent magnet motorHSPMM) three kinds of high speed rotor bearings are compared, followed by an overview of the problems linked to the rotor strength and dynamics analysis. Finally, development trends of the HSPMM related technologies are summarized and prospected. KEY WORDS: high speed permanent magnet machine; high speed be
