With the advantages of high power density, small size, high efficiency, high reliability and low operating cost, high-speed Motors have broad application prospects.The doubly salient electro-magnetic motor (DSEM) is suitable for high-speed operation due to its simple rotor structure. This paper aimed at high-speed and high-power DSEM first determines the structural parameters and analyzes the electromagnetic properties using Ansys Maxwell 2D; Then it proofreads the strength of the rotor in order to make an appropriate choice of the rotor lamination material; Finally it designs the cycle cooling system and gets the static temperature of the whole motor by simulating.
