Marine electric propulsion has the advantages of wide range of speed regulation, easy installation and flexible operation’ so it is a high performance propulsion and superior in many respects compared with mechanical propulsion. Permanent magnet synchronous motor (PMSM) has a series of advantages such as fast response speed, strong overload capacity, high power density and high efficiency, so it is very suitable for marine propulsion system. In this paper, a kind of marine permanent magnet synchronous motor was optimized by using Maxwell software. At the same time, the direct torque control technology was simulated by using mathematical modelling. Direct torque control (DTC) is a high performance AC speed regulation technology. As long as the appropriate voltage vector is selected, the system can be controlled to quickly follow the given speed and adapt to the change of torque. The simulation results show the good performance for the marine permanent magnet synchronous motor in this paper so that it can fully meet the requirements in both speed characteristics and torque characteristics.
