Cooling method of motor with propeller

Abstract

The invention discloses a cooling method of a motor with a propeller propeller. A propeller, a motor, a heat conduction device and a transmission device are included, the motor with the propeller is designed to be different in upper surface and lower surface, when downward airflow of the propeller flows through the motor with the different upper surface and lower surface, the upper surface of themotor is small, the lower surface of the motor is large, and positive pressure is generated on the upper surface of the motor due to airflow stagnation; negative pressure is generated when air flow passes through the large lower surface of the motor, a large static pressure difference is generated between the upper surface and the lower surface of the motor, more air flow passes a motor internal winding, therefore, the motor cooling efficiency is improved, according to the cooling method of the motor with the propeller propeller, no extra cooling device needs to be additionally arranged, onlythe shape of the motor needs to be changed, the cost is reduced, and the purpose of reducing the motor temperature can be achieved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a cooling method with a propeller motor. Background technique [0002] In the existing unmanned aerial vehicles, since the motor is cylindrical, and at the center of the propeller, the speed through the motor winding and the casing is relatively small, so the propeller does not have a good heat dissipation effect for the motor. For this purpose, we propose a cooling method with a propeller motor. Contents of the invention [0003] The object of the present invention is to provide a cooling method for a motor with a propeller to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: comprising propeller, motor, heat conduction device and transmission device, the method is: the motor with propeller is designed to have different upper ...
