    Abstract: A direct drive wind turbine and an electric generator for the wind turbine are disclosed. The generator may include a stator, a rotor spaced apart from the stator and a main shaft defining an axis of rotation, the main shaft at least indirectly connected to the generator rotor. The generator may also include a bearing assembly supporting the main shaft and defining a center of deflection on the axis of rotation. The generator may further include a convexly profiled air gap defined between the stator and the rotor, the air gap having a maximum width in regions of maximum deflection and a minimum width in regions of minimum deflection, the regions of maximum and minimum deflection determined with respect to the center of deflection.

    Abstract: A method for fabrication of a locomotive diesel engine turbocharger turbine stage so as to avoid harmonic vibration in the turbine blades when the engine is operated at pre-selected throttle settings. Upon determining throttle settings for the engine and modeling of the turbocharger therefor, at least one natural vibration frequency of the turbine blades and a turbine nozzle vane excitation frequency as a function of turbocharger rotation speed are determined. Then the data obtained is analyzed to ascertain whether at least one data coincidence, that is whether a rotation speed correlative of a throttle setting has a coincidence over a predetermined range of both a natural frequency and said turbine vane nozzle excitation. If not, the model is suitable for fabrication of the turbocharger; if so, the model is modified by changing blade stiffness and/or vane numbering until no data coincidences are present.
