Problems solved by technology

[0003] Plant protection drones are mainly composed of power system, power system, control system, spraying system and collective. The power system includes brushless motors and propellers. The propellers are likely to fail during long-term use. Most likely it will not affect the use of the brushless motor, so when there is a failure, the propeller needs to be replaced manually. For this reason, we propose a brushless motor used in plant protection drones

Abstract

The invention discloses a brushless motor for a plant protection unmanned aerial vehicle. The brushless motor comprises a limiting plate and a brushless motor body. The brushless motor body is fixedlyinstalled at the top of the limiting plate, a protective cover is arranged outside the brushless motor body, the bottom of the protective cover is fixedly connected with the upper surface of the limiting plate, and a first rotating shaft is fixedly installed at the output end of the brushless motor body; a second rotating shaft is arranged at the end, away from the protective cover, of the firstrotating shaft, the outer ring of the second rotating shaft is fixedly connected with a propeller, and a first clamping mechanism is fixedly mounted in the end, close to the second rotating shaft, ofthe first rotating shaft. The brushless motor for a plant protection unmanned aerial vehicle is provided with the first clamping mechanism and a second clamping mechanism. The two mechanisms are usedtogether to realize double fixation of the propeller, so that the propeller is more stable to install, the structure is ingenious, the installation of the propeller is simple and clear, the operationmethod is more convenient, and the operation is easy.

Description

technical field [0001] The invention relates to the technical field of drones, in particular to a brushless motor used in plant protection drones. Background technique [0002] Plant protection UAV, also known as unmanned aerial vehicle, as the name implies, is an unmanned aircraft used for agricultural and forestry plant protection operations. Composed of three parts, the spraying operation can be realized through ground remote control or navigation flight control, which can spray chemicals, seeds, powder, etc. [0003] Plant protection drones are mainly composed of power system, power system, control system, spraying system and collective. The power system includes brushless motors and propellers. The propellers are likely to fail during long-term use. It is possible that it will not affect the use of brushless motors, so when a fault occurs, the propeller needs to be replaced manually. For this reason, we propose a brushless motor used in plant protection drones. Conte...
