摘要： A wind turbine is provided having a drivetrain with a gearbox and a gearbox housing, at least one gear stage and an output shaft coupled within the housing. The gear stage exerts an axial thrust force on the output shaft during operation of the wind turbine. A generator includes a generator housing and an input shaft connected to the output shaft of the gearbox. The generator includes a rotor and a stator coupled to the generator housing. The rotor is coupled to the input shaft such that the rotor is positioned radially inward from the stator. At least one bearing is shared between the gearbox output shaft and the generator input shaft, and this bearing carries a portion of the axial thrust force. The generator is skewed to exert an opposing axial thrust force on the input shaft, so that the axial thrust force carried by the bearing is reduced.

摘要： Power is provided to the stator windings of an AC machine which includes a component at the fundamental drive frequency for the machine and a superimposed signal component which is at a substantially higher frequency than the drive power. The rotor has saliencies which result in a change in impedance as seen at the stator windings to the high frequency excitation signal as a periodic function of rotor rotational position. Such saliencies are inherent in some permanent magnet synchronous and all synchronous reluctance machines, and may be provided by appropriate modification of the rotor of induction machines. The stator response at the signal frequency is then detected to provide a correlation between the response at the signal frequency and the rotor position. The detection of the response at the signal frequency is preferably carried out by a heterodyne detection process, by mixing signals at the signal frequency with the measured stator currents, and filtering the mixed signals to isolate the signal indicative of the rotor position. Conventional squirrel cage induction motors can be provided with sufficient spatial variations in the stator winding impedance as a function of rotor position in various ways, including varying the depth and/or width of the slots over the rotor conductive bars, by varying the cross-section of the bars, or by filling or partially filling some of the slots.
摘要翻译：电力被提供给交流电机的定子绕组，其包括用于机器的基本驱动频率的分量和比驱动功率高得多的叠加信号分量。转子具有导致在定子绕组处看到的阻抗变化与高频激励信号的变化，作为转子旋转位置的周期函数。一些永磁同步和所有同步磁阻电机都是固有的这种效能，并且可以通过感应电机的转子的适当修改来提供。然后检测信号频率处的定子响应，以提供信号频率响应与转子位置之间的相关性。在信号频率处的响应的检测优选地通过外差检测处理来进行，通过将信号频率处的信号与所测量的定子电流混合，并且对混合信号进行滤波以隔离指示转子位置的信号。传统的鼠笼式感应电动机可以以各种方式作为转子位置的函数在定子绕组阻抗中提供足够的空间变化，包括通过改变横截面来改变转子导电杆上的槽的深度和/或宽度或通过填充或部分填充一些槽。
