FIELD: electrical engineering.
SUBSTANCE: brush gear comprises a group of brushes located in brush holders on the generator stator, the brushes are pressed by means of compression springs against the contact ring located on the rotor. According to the invention, each group of brushes is equipped with two elastic plates bent by a half-wave, which act as correctors for elastic forces of the compression springs. One end of the plate is attached with a fixed hinge to the stator, and the other end of the plate is pivotally hinged to the movable end of the compression spring.
EFFECT: providing a constant contact force between the brush and the ring on the rotor, which will increase the service life of the brush gear, improving the performance of the device.
