A direct drive vertical-axial wind power plant the power unit of which has structure of rotary generator includes a rotor with drive from a wind wheel that acts as a two-side inducer and comprises a circular set of magnets, and a stator that includes inductive modules, and a unit of the rotor unloading that includes a circular track made of electro-conductive diamagnetic material and fixed on a separate bearing. The rotor unloading unit is arranged as a magnetic bearing, that for the circular track is arranged as fixed, and the circular set of super-magnets is organized in order with alternation, where the sections of super-magnets alternate with sections of 5-element Halbakh grates, at that the dimensions of the massifs coincide with the dimensions of usual two-pole magnets of the rotor. The magnets of the rotor that adjoin each grate through an air gap have polarity opposite to polarity of the respective end element of the Halbakh grate. Possibility of variation of cycling of alternation of the magnets and the Halbakh grates brings up possibility of free control of the value of average magnetic energy of the circular set of super-magnets and re-distribution of flow of magnetic induction between the plane of the stator and the opposite plane of the bearing circular track. |
