Abstract:
A method of activating an electric machine having a stator, and a rotor which rotates about an axis with respect to the stator; the stator having a plurality of stator segments arranged about the axis; the rotor having modules made of magnetizable material and arranged about the axis; and the method including the steps of connecting the rotor to the stator by means of a bearing; and magnetizing the modules of magnetizable material when the rotor is connected to the stator.
Abstract:
A wind power turbine control method, the wind power turbine having an electric machine, in turn having a stator, a rotor rotatable about an axis of rotation with respect to the stator, and a mechanical bearing assembly configured to couple the rotor in rotary manner to the stator; the stator having at least one winding to interact electromagnetically with the rotor; and the control method including the steps of: estimating at least one quantity selected from a group including a distance between the rotor and the stator, the variation over time in the distance, and misalignment between the rotor and stator; defining a localized additional magnetic force as a function of the selected quantity; and regulating the selected quantity using the localized additional magnetic force defined.
