The invention discloses a high-stability unmanned aerial vehicle motor rotor. The motor rotor comprises a shell, wherein a cavity is formed in the shell, a carbon
fiber layer is connected with the cavity, the carbon
fiber layer is arranged on an inner side wall of the shell, and a
graphene layer is arranged on one side, away from the shell, of the carbon
fiber layer. The motor rotor is advantagedin that a plurality of
layers of films are arranged between a
stator and a rotor, abrasion of the rotor to a side wall of the
stator during use can be reduced to a certain extent, the service life ofthe whole motor can be prolonged, secondly, the films are arranged for multiple times, when one film is abraded and damaged, a user can maintain the motor and replace the film matched with a model ofthe motor by himself / herself, maintenance is convenient and fast, the user does not need to search special maintenance personnel, certain maintenance cost is saved, the motor further has the good sound insulation effect, when the motor is used by the user, other people are not prone to being disturbed by too large
noise.
