摘要： It is described a permanent magnet assembly (360, 460) comprising a first side magnet device (280a), a second side magnet device (280b) and a central magnet device (270, 470) in between. The central magnet device (270, 470) has a spread angular distribution of magnetic domain alignment directions (375, 475) resulting in a focused magnetization defining a focal point (377). Both side magnet devices (280a, 280b) have only a single magnetic domain alignment direction (382a, 382b) resulting in a parallel magnetization. The single magnetic domain alignment direction (382a, 382b) is slanted with respect to a magnetic axis (377a) being defined by the shortest distance between the focal point (377) and a main surface (270a) of the central magnet device (270, 470). It is further described a rotor assembly (150) with such a permanent magnet assembly (360, 460), an electromechanical transducer (140) with such a rotor assembly (150), and a wind turbine (100) with such an electromechanical transducer (140).

摘要： It is described an apparatus (460, 560) and a method for manufacturing a sintered flux focusing permanent magnet (250, 350). The apparatus comprises (a) a mold (470, 570) having a molding chamber (472, 572) for receiving a powder of a permanent magnet material (495, 595); and (b) a first magnetic device (461, 561-1, 561-2) and a second magnetic device (464, 564) both for generating a magnetic field for magnetizing the powder (495, 595) being accommodated within the molding chamber (472, 572). The first magnetic device (461; 561-1, 561-2) comprises a first yoke structure (463; 563-1, 563-2) having a first shape and the second magnetic device (464, 564) comprises a second yoke structure (466, 566) having a second shape. The second shape is spatially different from the first shape. Further, the spatial difference in the shapes of the two yoke structures (463, 466; 563-1, 563-2, 566) causes the magnetic field to be inhomogeneous in such a manner that the magnetic field within the molding chamber (472, 572) is associated with a spread angular distribution of magnetic flux lines. Further described is a Sintered flux focusing permanent magnet (250, 350) which has been produced with the described method and an electromechanical transducer (140) as well as a wind turbine (100) comprising a sintered flux focusing permanent magnet (250, 350).

摘要： It is described an apparatus (460, 560, 660) for manufacturing a sintered permanent magnet (250, 350). The apparatus comprises (a) a mold (470, 570) having a molding chamber (472, 572, 672) for receiving a powder of a permanent magnet material (495, 595, 695); (b) at least two magnetic devices (461, 464; 561, 564) for generating a magnetic field for magnetizing the powder being accommodated within the molding chamber; and (c) at least one die for compacting the powder being accommodated within the molding chamber; the magnetizing and compacting resulting in a magnetized compacted block of the powder (495, 595, 695). The molding chamber and/or the die comprises at least one surface (470a, 470b; 570a, 570b) which is curved in such a manner that an unwanted deformation of a sintered block, which has been obtained by sintering the magnetized compacted block in a sintering oven, whereby the unwanted deformation is given after a removal of the sintered block from the sintering oven, is compensated at least partially. Further described is a method for producing a sintered permanent magnet with such an apparatus, a sintered permanent magnet which has been produced with such a method, and an electromechanical transducer (140) and a wind turbine (100) comprising such a sintered permanent magnet.
