GEARLESS WIND ELECTRICAL UNIT Russian patent published in 2014 - IPC F03D9/00 

FIELD: electricity.

SUBSTANCE: gearless wind electrical unit comprises a tower, a rotary base, equipped with a wind wheel with segment rotor elements and a bushing installed into bearings, a bracket with stator elements, which include tips, working coils, a source of excitation and a tail guide element. Segment rotor elements are made in the form of angles, horizontal shelves of which are connected with a rotor rim, vertical shelves are connected with blades, the first pole tips are installed in the zone of an axial air gap with horizontal shelves of angles, and the second pole tips are arranged in the zone of an end air gap with vertical shelves of angles.

EFFECT: high manufacturability, specified by a simple shape of stator elements, improved characteristics of an air gap, increased total length of an air gap, reduced magnetic resistance and mass of dimensional parameters of a stator element at the same cost, which as a result increases energy efficiency.
