Problems solved by technology

Through the test, it is found that frequent starting or long-term load operation of the motor will cause the motor to overheat, and overheating may cause the motor to fail, resulting in the failure of the propulsion system
[0003] At present, there is no good solution for the heat dissipation of multi-rotor motors. Digging grooves or holes on the rotor can achieve a certain effect.

Abstract

The invention discloses a multi-rotor motor. The multi-rotor motor comprises multiple fan vanes formed on the top of an external rotor of the motor. The root of each fan vane is fixedly connected to a rotor shaft of the multi-rotor motor, and the tip of each fan vane is fixedly connected to a rotor shell of the multi-rotor motor. Under the condition of the multi-rotor motor and blades, the multiple fan vanes are located at the end of the multi-rotor motor near the blades.

Description

technical field [0001] The invention relates to the field of aircraft and the field of motors, in particular to a multi-rotor motor. Background technique [0002] At present, with the continuous improvement of technology, multi-rotor aircraft has been applied in more and more fields. As a multi-rotor propulsion system, the working reliability of electric motors and blades is extremely important. Through tests, it is found that frequent starting or long-term load operation of the motor will cause the motor to overheat, and overheating may cause the motor to fail, thereby leading to the failure of the propulsion system. [0003] At present, there is no good solution for the heat dissipation of multi-rotor motors. Digging grooves or holes on the rotor can achieve a certain effect. At the same time, check before the test flight or listen to the sound of the motor to judge whether the motor is damaged. [0004] Therefore, those skilled in the art are devoting themselves to deve...
