Problems solved by technology

[0002] A brushed motor includes a stator and a rotor 1. The rotor is provided with a commutator 11. The motor is provided with a brush to contact the commutator 11. The existing brushed motor mainly adopts a relatively wear-resistant graphite brush 3, such as figure 1 As shown, the existing graphite brush 3 is a rigid graphite block, which is pushed by a spring 4 to keep the graphite brush 3 in good contact with the commutator 11, and the graphite brush 3 and the commutator 11 on the rotor 1 are in relative motion At this time, the graphite brush 3 is rubbed against the commutator 11 closely, and there is rigid friction between the two, which generates very large noise, and the graphite brush 3 is prone to beating and sparks; in addition, the graphite brush 3 and the commutator The rigid friction between the guides 11 will be like sandpaper rubbing against objects, causing the wear of the graphite brush 3, and the life of the motor will end when the brush is worn out. The existing graphite brush 3 is generally used for several months to a year. All wear and tear will cause the motor to be scrapped and seriously affect the service life of the motor

Abstract

The invention discloses a carbon fiber brush motor which comprises a rotor and a stator. The rotor is provided with a commutator, the commutator is provided with the brush, and the brush a soft brush prepared by conductive carbon fibers. Compared with the prior art, the carbon fiber brush motor employs the soft brush prepared by the conductive carbon fibers, and bristles of the brush are resistant to high temperature and wearing, are soft and make soft contact with the commutator; when the brush runs opposite to the commutator of the rotor, the soft bristles cling to the commutator, bend along the rotation direction of the commutator, do not bounce, and tend not to generate spark; the friction generated between the bristles and the commutator is very low, almost no noise exists, the frictional loss of the bristles is greatly reduced, the bristles tend not to wear, and the service life of the motor is prolonged.
