Applications of Permanent Magnet Motor on Electric Propulsion Ship

摘要

Electric propulsion technique on warships has been growing increasingly important for world's navies. It's regarded as the direction for future warships. As the core of electric propulsion ship, propulsion motors and generators decide the main characteristics. Since permanent magnet(PM) motor has obvious advantages, it will be the first choice for future electric propulsion ship. In this paper, history of propulsion motors is introduced, then from the basic principles of PM motor, comparison with traditional propellers and main characteristics are also interpreted. According to the research and applications of PM motor, it can be predicted that it will finally replace tradition synchronous propulsion machine.
