Abstract: With the rapid advancement in machine design and power electronics, naval ship electric drive propulsion system becomes an attractive and fastgrowing research area. The main power source of naval ship electric drive propulsion is the drive motor, whose characteristics are determined by the requirements of ship's operation. As the speed and propulsion power of the ship changes greatly, the power range and speed range of the drive motor should be wide enough to satisfy multiple operation. This paper introduced four drive motors with high power densities and efficiencies which were very suitable for naval ship electric drive propulsion system: the advanced induction motors, the permanent magnet synchronous motors, the high temperature superconducting synchronous motor and the superconducting homopolar DC motor. The comparison of different drive motors and the trends in naval ship propulsion drive motor technology were also presented in this paper.
