INDUCTOR GENERATOR WITH AIR COOLING SYSTEM Russian patent published in 2021 - IPC H02K19/20 H02K9/06 H02K5/20 H02K1/20 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the electrical equipment. Inductor generator with air excitation system has two toothed stacks of stator installed in housing with installed spacer. Spacer is made in the form of hollow cylinder of non-magnetic material with grooves made in it, coaxial with slots in stator packs and recesses in its teeth. Female anchor armature enveloping teeth. Two gear pack rotated by 180 degrees with excitation winding in the form of two coils separated by non-magnetic, fixed on spacer, frame with gaps between outer lateral and lower surfaces and surfaces of rotor and shaft corresponding to them respectively. Component part of the internal cooling system of the generator also includes radial holes and cuts in the excitation winding frame carcass with recesses in the spacer and casing with the branch pipe. Holes in the stator housing and a fan mounted on the shaft, which also provides operation of the external cooling channel, in the form of a cavity enveloping the housing and closed with a metal shell. Cooling air flow into this cavity is supplied from branch pipe, and is ejected into inner cavities of generator through holes in housing.

EFFECT: technical result consists in reduction of weight and size parameters and improvement of cooling.
