Abstract

The invention discloses a testing device for drone motor and propeller combination, and belongs to the field of drone testing. According to the testing device for the drone motor and propeller combination,a drone motor is directly connected with a propeller, so that a lift force and a torsion force are relatively independently tested, the test is not easily limited by a rotating speed, and an instrument can be checked on site at any time, so that using is convenient and the test installation requirements are met; meanwhile, under the cooperation effect of double-variable liquid and an embeddedself-connecting plate, on one hand, the fixation between an output shaft and a center connecting shaft can be realized through the automatic change of a magnetic field during connection, so that theinstallation of the propeller is extremely simple and convenient, and the test efficiency is effectively ensured; and on the other hand, during high-rotating-speed test, the deviation or skewing phenomenon caused by high speed can be inhibited in time, so that the stability during testing is effectively ensured, the accuracy of data is effectively improved, meanwhile, abnormal sound caused by poorstability during high-speed testing can be reduced, and the stability of a testing result is further improved.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle testing, and more specifically, relates to a combination testing device of an unmanned aerial vehicle motor and a propeller. Background technique [0002] With the development of the economy and continuous research and development in the direction of electronic technology, propeller drones have been widely used. The motor and propeller are the power system of the UAV. The motor drives the rotation of the propeller to provide power for the UAV to rise. Its performance directly determines the flight safety and flight efficiency of the UAV. Therefore, we need to conduct performance tests on the motor propeller, including: lift, speed, power, force effect, torque, etc., and analyze the data obtained to continuously improve the performance of the motor propeller. [0003] In the traditional motor propeller test bench, we use the torque speed sensor placed between the motor and the propeller to d...
