    • Das Verfahren dient zum Auslegen der Statorwicklung eines Asynchronmotors eines Kreiselpumpenaggregats. Haupt- und Hilfswicklung des Asynchronmotors werden über mehrere Statornuten verteilt angeordnet, und zwischen Stator und Rotor wird ein magnetisch leitendes Spaltrohr vorgesehen. Um die mit dem magnetisch leitenden Spaltrohr einhergehende Geräuschemission des Aggregats zu verringern, andererseits jedoch den Wirkungsgrad nicht in gleicher Weise zu verschlechtern, ist es vorgesehen, die Verteilung der Wicklungen in den Statornuten so vorzunehmen, dass die Amplitude der das Antriebsmoment erzeugenden ersten harmonischen Schwingung 0,75 bis 0,85 des theoretischen Maximalwerts der Amplitude der ersten harmonischen Schwingung bezogen auf die in einem Nutpaar konzentrierte Wicklung beträgt und dass die Amplitude mindestens der nachfolgenden zwei höhergeordneten ungeraden Schwingungen eine Größe von höchstens 15 % des vorgenannten Maximalwerts nicht überschreiten und in ihrer Größe voneinander mit Ausnahme der nutharmonischen höchstens um 50% abweichen.

    • A drive member is rotatable or movable straight on a principle different from the principle of conventional three-phase or single-phase induction motors. The drive member 4 of the device of the invention is made of electrically conductive nonmagnetic material, supported rotatably or movably straight and uniform in wall thickness and width. An outer magnetic member 2 and an inner magnetic member 3 are arranged respectively at the outer side and the inner side of the drive member which are orthogonal to the direction of movement thereof.
      At least one of the outer and inner magnetic member has at least three magnetic poles 22 or 32 to provide closed magnetic circuits extending from the respective poles and penetrating the drive member and the magnetic members along a round path. The poles have a smaller width than the drive member and are arranged centrally of the drive member, so that the drive member has edge portions 41, 41 which are not opposed to the poles, at opposite sides thereof which are orthogonal to the direction of movement. When fluxes with at least three phase differences are produced at the respective poles of the magnetic circuits, each flux generates an induced current in the drive drive member, whereby an electromagnetic force acting on the drive member is produced between the flux and the current to move the drive member relative to one or both of the outer and inner magnetic members.
    • 驱动构件可以以与常规三相或单相感应电动机的原理不同的原理可旋转或可直线运动。 本发明的装置的驱动构件4由导电的非磁性材料制成,其可旋转地或可移动地被支撑成直径且壁厚和宽度均匀。 分别在驱动部件的与其移动方向正交的外侧和内侧配置有外部磁性部件2和内部磁性部件3。 外部和内部磁性构件中的至少一个具有至少三个磁极22或32,以提供从各个极延伸的闭合磁路,并沿着圆形路径穿过驱动构件和磁性构件。 这些极具有比驱动构件更小的宽度并且布置在驱动构件的中心,使得驱动构件具有边缘部分41,41,其在与其移动方向正交的相对侧处不与极相对 。 当在磁路的各个极处产生具有至少三个相位差的磁通时,每个磁通在驱动驱动构件中产生感应电流,由此在磁通和电流之间产生作用在驱动构件上的电磁力以移动 所述驱动构件相对于所述外磁构件和所述内磁构件中的一个或两个。

    • Winding in electric machine with center coil in field center in the pair of poles and auxiliary coils in the field of each one of the two poles in the pair of poles in the stator. The two primary coils in each one of the pair of poles in the stator are replaced by a single center coil in the field center in the pole. The power of the electric machine, of the transformer and the coil are dependent on its core area elevated to the square. For the purpose of distribution of the coil powers in an electrical machine with auxiliary coils, use is made of a factor that provides the appropriate load of the stator and rotor cores. The number of slots in the stator is reduced by increasing the number of turns in the center coil in the field. The stator is optimized by means of the use of the square root of the power of a coil over the core area thereof. In hermetically sealed refrigeration compressors, the massive central shaft is accommodated in the rotor. The center core in the transformers is from 2 times reduced to ˆš 2 times the height of the ring core.
    • 在定子中的一对电极中的两个电极中的每一个磁场的场中,中心线圈位于场极对中的一对极和辅助线圈中。 定子中一对极中的每一个中的两个初级线圈由极中的场中心中的单个中心线圈代替。 电机,变压器和线圈的功率取决于其核心区域升高到正方形。 为了在具有辅助线圈的电机中分配线圈功率,使用提供定子和转子芯的适当负载的因素。 通过增加现场中心线圈的匝数来减少定子中的槽的数量。 通过在其核心区域上使用线圈的功率的平方根来优化定子。 在密封制冷压缩机中,大型中央轴容纳在转子中。 变压器的中心铁芯从2倍缩小到环芯高度的2倍。
