Focus on detecting the response of the motor ESC to different frequency excitations, and the synchronization of multiple motors. First complete the ESC calibration, and then operate the remote control joystick at different frequencies (such as slow, medium, and fast) to excite the ESC motor to see if the response of the motor can follow the excitation, whether there is any obvious delay or stuck or stuck phenomenon , check how the ESC handles the given excitation signals of different frequencies, whether there is filter protection processing, and short-term overload protection. Especially now due to the popularity of the agricultural spray drone market, many agricultural drone manufacturers undertake customized motor ESCs, but there are some problems in the performance matching of motor ESC products, and the performance of the motor cannot be effectively used, and the driving motor is bad. Of course, sometimes because of the problem of custom motors, there are serious large inertia and nonlinear characteristics, which are not suitable for multi-rotor UAVs. In terms of detecting synchronization, you can use a remote control channel to connect all ESC motors at the same time, operate the remote control joystick at different frequencies (such as slow, medium, and fast) to excite the ESC motors to see if all motors can follow the excitation synchronously.
