Latest update on the topic of DIY motor kit from Banggood (DIY Assemble 2204 2-3S Brushless Motor 0.42*2.8 Copper Wire with Motor Cap Banana Plug): I give up. For now, at least.
In total, I tried to wind this motor 6 times. In every single case it ended in the same way: one of the phases burned. So, it's either me, or this kit. I've verified winding directions and termination schema for at least few times, and if I didn't missed something extremely obvious, I did it in a right way. I even verified winding directions during "unwinding". So I start to suspect, that this motor is either no 12N14P DLRK (not very probable), or it should not be winded with 0.42mm wire. Next week I will order 0.20mm wire and try one more time…
This is a winding schema I used:
Poles goes as follows: AabBCcaABbcC where capital letter is clockwise, while small letter is counter-clockwise.
Phases were connected like this:
Sure, I could have done something wrong. But not 6 times in a row…
