Although a motor may pass a continuity test, this alone doesn't guarantee its health. Poor winding quality and loose wire terminals can cause induction interference, leading to overheating and potential short circuits.
thank you very much, this is useful *in my case: one of the motors on my drone was broken but i don't know which one because in plain view everything looks normal, but when flown, my drone vibrates and is difficult to control, do you have any idea what I have to do to find a broken motor?
To find the offending motor, you can just do a motor test in betaflight. Spin each one to full then back, make sure to remove your props. You'll hear and feel which motor is giving low power or excessive vibration.
WTF?? In the time it would take to do all that nonsense you could of hooked up a motor to an esc two times. Spinning your motor physically with another motor is not going to give an accurate reading and is more likely to damage the motor in need of testing than ESC would harm it.
Yes you are right that that's a quicker way to test a motor, but sometimes just because it spins doesn't mean it's ok. Some motors will spin and even fly despite having a short in one of their phases. This can happen if the short is somewhere in the middle of the wind where the insulation has melted; that phase will still work, but just like it had less winds. Motors that have this problem usually get hot and eventually fail mid flight. JB has a similar video if you want to check it out; he uses a drill instead.
@@emp29, Yeah, I just ran across that one. I have NO IDEA what was up my butt when I left that response, I just read it back, sorry, that came off very dickish. Been out of work and trying to get a side drone business started, have some crabby days here n there. I am absolutely sure there is need at times to test them that way, if nothing else just as a back up test if you want to be positive. I have no room to talk the way I MacGyver some of my quads with very non traditional hacks and short cuts...lol. Sorry again, happy flying! ✌️
@@sunshynff no worries, bro. You brought up valid points which even JB mentioned in his video on doing this. I'm sure it would be good reading points for those who are just starting out in the hobby. Happy flying!
