An electrical stabilizer (1) for stabilizing a floating structure is described. The electrical stabilizer (1) comprises a rail (2) for guiding a rotor (6) as a moving stabilizer mass. A direct current (DC) linear motor (8) comprises a planar stator (10) extending along a track (2) and a mover (6) adapted to move forward and backward along the track (2) as a stabilizer mass. The planar stator (10) includes a multi-phase stator winding (16) having a plurality of winding coils (14) connected to define a plurality of phase windings. The mover (6) comprises a plurality of permanent magnet motor magnets (40) facing the multi-phase stator winding (16) defining a plurality of mover poles of alternating polarity (i.e., north and south poles) along the orbital direction. Two active magnetic bearings (44, 48) are placed between the track and the body (32) of the mover (6) for selectively suspending the mover. In use, active magnetic bearings (44, 48) suspend the mover (6) above the track, and a DC linear motor (8) is controlled to move the mover (6) forward and backward along the track (2), for example to suppress rolling or pitching movement of the floating structure.

    描述了一种用于稳定浮动结构的电稳定器(1)。电稳定器(1)包括用于引导作为移动稳定器质量的动子(6)的轨道(2)。直流(DC)线性马达(8)包括沿着轨道(2)延伸的平面定子(10)和适于作为稳定器质量沿着轨道(2)向前和向后移动的动子(6)。平面定子(10)包括具有连接以限定多个相绕组的多个绕组线圈(14)的多相定子绕组(16)。动子(6)包括面对多相定子绕组(16)的限定沿着轨道方向的交替极性(即,北极和南极)的多个动子磁极的多个永磁马达磁体(40)。两个主动磁轴承(44,48)放置在轨道和动子(6)的主体(32)之间以用于选择性地悬浮动子。在使用中,主动磁轴承(44,48)将动子(6)悬浮在轨道上方,并且DC线性马达(8)被控制以沿着轨道(2)向前和向后移动动子(6),以例如抑制浮动结构的翻滚或俯仰移动。
