FIELD: electrical machine building.
SUBSTANCE: invention can be used in designing electrical machines. Brush-contact apparatus (BCA) of the generator consists of a contact ring located on the rotor, and several groups of brushes located in brush holders on the generator stator, which are pressed to the contact ring located on the rotor by means of compression springs, into each group of brushes, an elastic bent half-wave plate is introduced, which acts as a corrector of the elastic force of the compression spring, one end of the plate is fixed by a fixed hinge on the stator, and the second end of the plate is hinged to the movable end of the compression spring, and the guide, the movable part of which is attached to the movable end of the spring, and the fixed part to the stator.
EFFECT: reduced overall dimensions of the device while providing a constant contact force between the brush and the ring on the rotor due to one elastic plate, which increases service life of brush-contact apparatus, improves operational characteristics of the device.
