The invention discloses a magnetic suspension permanent magnet motor wheel rim driving propeller, which comprises a shell, a stator assembly and a rotor assembly, and is characterized in that the stator assembly comprises a stator yoke hermetically mounted in an inner cavity of the shell, and a suspension force stator winding and a torque stator winding which are mounted on the stator yoke; the rotor assembly comprises a rotor ring, a permanent magnet fixed to the outer side wall of the rotor ring and blades installed on the inner ring side of the rotor ring, the stator assembly is located outside the rotor assembly, a gap is formed between the stator assembly and the rotor assembly, and an auxiliary mechanical bearing and an axial magnetic suspension bearing are further installed between the rotor assembly and the shell. The number of pole pairs of the suspension force stator winding and the torque stator winding is not equal so as to form magnetic fields with the permanent magnets on the rotor ring. The magnetic suspension permanent magnet motor rim driving propeller is simple and compact in structure, high in propelling efficiency, small in noise vibration and suitable for being applied to a subminiature propelling system of a ship.

    本发明公开了一种磁悬浮永磁电机轮缘驱动推进器,包括壳体、定子组件以及转子组件,定子组件包括密封安装于壳体内部腔室中的定子轭、以及安装于定子轭上的悬浮力定子绕组和转矩定子绕组;转子组件包括转子环、固定于转子环外侧壁上的永磁体、安装于转子环内环侧的桨叶,定子组件位于转子组件外部且二者之间设置有间隙,转子组件与壳体之间还安装有辅助机械轴承和轴向磁悬浮轴承,悬浮力定子绕组和转矩定子绕组的极对数不相等以分别与转子环上的永磁体形成磁场。本发明提出的磁悬浮永磁电机轮缘驱动推进器,其结构简单紧凑、推进效率高且噪声振动小,适合应用于船舶的超小型推进系统中。
