High-stability unmanned aerial vehicle motor rotor and production method thereof

Abstract

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.

Description

Technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to a high-stability unmanned aerial vehicle motor rotor and a production method thereof. Background technique [0002] A motor is a device that converts electrical energy into mechanical energy. It uses energized coils (that is, stator windings) to generate a rotating magnetic field and act on the rotor (such as a squirrel cage closed aluminum frame) to form a magneto-electric power rotating torque. Motors are divided into DC motors and AC motors according to different power sources. Most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors (the motor stator magnetic field speed and the rotor rotation speed do not maintain synchronous speed). The motor is mainly composed of a stator and a rotor. The direction of the force movement of the energized wire in the magnetic field is related to the direction of the current and the ...

AI Technical Summary

Problems solved by technology

[0004] However, during the use of the existing UAV motor, the stator is damaged due to the rotor rubbing against the stator for a long time. Since the processing procedure of the stator is relatively complicated, it is not easy to replace the stator after it is damaged. This requires the user to Replace the motor as a whole, which increases the maintenance cost of the user, and the damaged motor cannot be used, wasting resources
