UNIPOLAR GENERATOR Russian patent published in 2018 - IPC H02K31/00 H02K31/02 

FIELD: electricity.

SUBSTANCE: unipolar generator contains the first generating module (1) and the second-generation module (2) made identical and connected by a shaft (3). Each generating module (1, 2) comprises a housing (4) with bearings (5) mounted therein, in which the shaft (3) is fixed, and with poles (6) located inside of it, on which excitation windings (7) are mounted, and an armature disc (8) mounted on the shaft (3) between the poles (6). On the outer end surfaces of the armature discs (8), beads (9) are formed in the form of rings of width b=Δ and height h=3⋅Δ, where Δ - the thickness of armature disc (8). On the outer surface of beads (9), the first brush (10) and the second brush (11) paired with it are arranged, distributed in the form of prismatic semirings from the composition of coal and graphite. The first (10) and second (11) brushes are fixed with respect to the housing (4) by springs (12) with guide rods (13), the grounds of which are fixed on the mounting thickenings (14) of elastic plates (15), executed in the form of flat arcs of high elastic steel with high electrical conductivity. Brushes (10, 11) are covered by elastic plates (15), forming single collector nodes of the first (1) and second (2) generating modules. The free edges of springs (12) are installed in the insulating supports (16) located in the housing (4) and made of plastic with low electrical conductivity. Between the surfaces of insulating supports (16) and the guide rods (13), gaps are made that exceed the length of the possible radial displacement of brushes (10, 11). Brush (10) output (17), which is also the brush (11) output, and an output (18) of excitation windings (7) are mounted on the housing (4). The elastic plates (15) are connected by flexible conductors (19) to the output (17) of brushes (10, 11).

EFFECT: expanding the scope of unipolar generators.
