Patent attributes
A unit for conversion of fluid stream energy into electric energy is proposed, in one embodiment comprises two turbines rotatable in opposite directions, furnished with aerodynamically-profiled blades, each having a ‘V’-shape evolvement line, then bent to produce a helix line wound upon a cylindrical surface, and an electro-generator including two short-circuited rotors coupled with the blades and an immovable inductor with a three-phase winding, magnetically associated with the rotors. The inductor includes a yoke, teeth located at each its side, stationary magnetic plates attached to the unit's structure via non-magnetic insertions. The winding is composed of coils comprising wires placed between the teeth, wherein the active sides of two phase coils are shifted relatively to each other being parallel to the longitudinal axis of said inductor, and phase-wise are oppositely shifted, wherein the two phase coils are situated adjacently to a third phase coil from the opposite sides thereof.
