I have 4 brushless motors with ESC, wired to the same power source and same Servo tester, so they should all work together, at the same time.
When I turn the Servo tester a few mm, two motors starts to work - and slow. (as expected) But for some reason not all of the motors start.
The other motors start to work just when I turn the Servo tester more - a third motor will start after something like 1/4 turn of the Servo tester, and it starts fast (the speed you would expect it to have when the Servo tester is 1/4). Another motor starts after 2/4 turn of the tester, and so on.
And since the motors start to work just after the Servo tester is already turned, they don't have the same range. (because they immediately start fast, and in different points)
- My battery is LIPO 11.1V , 5000mAh.
- The motors are A2212 1000KV Brushless with ESC.
- When I swap the cables of the motors (to check that it's not just a bad wiring) then it doesn't change anything. The same motor always starts first, doesn't matter if I swap the cables connections with the motor that starts last.
The battery is charged, and everything is wired correctly. (well, all of the motors "work", just not as expected)
I use L298N motor controller to get 5V for the servos.
I'm testing the motors without Arduino, so there isn't software.
(I think this is all of the important, useful information)
Does anyone have any suggestion what can cause this issue? I'm not an expert with electronics (to say the least), and I didn't find anything that can explain it.
Can it be a not good solder joint, that makes the motor require more power in order to start working? I don't know if it sounds stupid, but.. I'm just trying to suggest ideas
(And it that's possible, then I'll try to re-solder the connections, but I want to make sure that it can even be an issue, before doing so)
I'll really appreciate any help!
P.s if you have good resources for learning about electronics, I'd like to know, since I want to learn and get better in that field, thanks!
So I checked each motor seperately, and seems like some motors start just with higher values (from the servo tester) - even if that's a single motor, so what can cause that?
