    • The invention relates to a boat propulsion system comprising at least one propeller (8), at least one electric motor (7) by means of which the at least one propeller can be driven, and one converter-fed power supply unit. The at least one electric motor (7) can be supplied with electric power by means of said power supply unit which comprises at least one prime mover and at least one generator powered by said prime mover. The at least one electric motor and the at least one generator of the power supply unit are embodied as three-phase synchronous machines. In order to reduce the volume and weight of such a boat propulsion system while increasing its effectiveness, the at least one electric motor (7) that is configured as a three-phase synchronous machine and the at least one generator that is configured as a three-phase synchronous machine of the power supply unit have rotating excitation coil (10) made of high-temperature super conductor wire and each rotating excitation coil (10) made of high-temperature super conductor wire is arranged in a vacuum-tight, insulated cryostat (14) by means of which the rotating excitation coil (10) made of high-temperature super conductor wire can be chilled to a temperature of 15 to 77 K.
    • 船舶推进系统技术领域本发明涉及一种船舶推进系统,该船舶推进系统包括至少一个螺旋桨(8),至少一个电动机(7)以及一个转换器供电单元,借助该电动机可以驱动至少一个螺旋桨。 所述至少一个电动机(7)可以借助于所述电源单元被供电,所述电源单元包括至少一个原动机和由所述原动机供电的至少一个发电机。 电源单元的至少一个电动机和至少一个发电机被实施为三相同步电机。 为了在增加其有效性的同时减小这种船推进系统的体积和重量,构造为三相同步电机的至少一个电动机(7)和构造为三相的至少一个发电机 电源单元的三相同步电机具有由高温超导线制成的旋转励磁线圈(10),并且由高温超导线制成的每个旋转励磁线圈(10)布置在真空密封绝缘低温恒温器 (14),由此可以将由高温超导导线制成的旋转励磁线圈(10)冷却至15至77K的温度。
