Feasibility study of a new magnetic levitation shaftless propeller

Ships are high-consumption means of transportation. As a large energy consumer, the fuel cost is extremely high. Therefore, the fuel consumption can be reduced by optimizing the form of propellers. For traditional propellers, the shafting is one of the main sources of ship vibration, and the transmission structure is complex and the cost is high. Therefore, starting from the form of a shaftless propeller, the author cancels the transmission structure such as the shafting, adopts the electromagnetic drive propeller, and introduces The magnetic levitation technology avoids the problems of friction, vibration and noise when the propeller is running. At the same time, the method of fully enclosed fairing is adopted, so that the design has good sealing performance. The maglev propeller is more suitable for ships with all-electric propulsion systems, with no risk of oil leakage and no harmful gas emissions. It is very suitable for small and medium-sized ships.
