Paper Title: The Development of a Linear Induction Motor as a Marine Propulsion System



M Geor, S Hooper, S Tamakai, Royal New Zealand Navy, New Zealand
A P R Taylor, AUT University, New Zealand


The Linear Induction Motor (LIM) has been employed as an actuator in conveyers and more recently aircraft launches, and some work has been done on LIMs with a curved secondary reaction plate. This paper presents a working model of a marinised LIM-boat system, with underwater stator operating the hull of a boat which acts as reaction plate. The LIM stator is shown to propel the boat through the water, and that with certain reaction plate metals it will track over the stator coils and therefore be controllable in both direction and speed. Test results for differing coils and reaction plate combinations are provided.
