Problems solved by technology

Since the motor fixing plate is not properly fixed, the torque of the propeller and the motor will have a lateral impact on the motor fixing plate, thereby further affecting the signal acquisition of the pressure sensor. At the same time, due to the need to overcome the flexible force of the bracket, the pressure sensor Difficulty obtaining accurate pressure values
[0004] The existence of these problems makes it difficult for existing force sensors to accurately measure the force parameters of electric aircraft

Embodiment Construction

[0014] The present invention will be further described in detail below with reference to the drawings and embodiments:

[0015] Such as figure 1 As shown, the present invention discloses a force effect tester adopting a dual slide rail design. Two symmetrical slide rails 3 are arranged on the base 2, and the slide end 4 is fixed to the symmetrical slide rail 3. The motor mounting frame 6 is fixedly installed on the upper side, and the tensile tester 1 and the sliding end are fixedly connected by bolts or the like. The motor mounting frame 6 can be adapted to install different types of batteries, ESCs, motors and propellers. A test circuit board 5 is installed on the motor mounting frame 6, and the test circuit board 5 has an on-board main control single-chip. Connect the battery to the input end of the test circuit board, connect the power supply line and control line of the ESC to the output end of the test circuit board 5, connect the output end of the ESC to the motor, and f...

Abstract

The invention provides a force effect tester. The force effect tester comprises a base, slide guide rails which are symmetrically arranged on the base, a slide end which is fixed on the slide guide rails, a motor mounting rack which is fixed at the slide end, and a tensile force tester which is connected with the slide end, wherein a test circuit board with an onboard master control single chip microcomputer is arranged on the motor mounting rack; the single chip microcomputer is used for testing integral voltage and current through a sensor with a power supply plate, reading results of the tensile force tester, calculating the force effect by combining various results according to the set program, and displaying and recording the force effect on the single chip microcomputer and a display device thereof; the test circuit board 5 further can be connected with a remote-control receiver to supply power to the receiver, and a control signal of the receiver can be connected to control power transfer.

Description

Technical field [0001] The invention relates to a testing instrument, in particular to a testing instrument for measuring the overall force efficiency of a motor and a propeller, belonging to the field of testing instruments. Background technique [0002] In the development process of electric aircraft, the flight efficiency needs to be calculated. Therefore, it is necessary to detect and obtain a key parameter-power efficiency. Power efficiency is used to measure the indicator between power consumption and execution efficiency, which can be directly used to calculate flight time. In order to obtain power efficiency, it is necessary to use a professional instrument for testing the efficiency of the electric power system, that is, a power efficiency test instrument. [0003] The existing force effect test method is to directly connect the blades to be tested to the motor fixing plate in the motor fixing barrel, and install a pressure sensor on the motor fixing barrel, the motor fix...
