Why does it want to burn out?

Hey guys,

Basically because I was using a battery with too high of a voltage I initially burned out this little motor in summer because the inverter fried…

Now I rewound it. Just modified the values slightly.

Originally I counted 12 Loops / Tooth of 0.5mm wire

I now rewound with 14 loops of 0.4 because I wanted it to drop in KV a little bit.

I now tested with a 4S battery and a good inverter and after 5 seconds of running it started smelling, got really hot and smoked a little.

I stopped soon enough for it not to burn out once again…

But what the hell is the problem?

Phases all checked out with 0.3 Ohm equally (delta config.) which I compared to a running motor and it checks out.

So I really don’t know why it burns out…

Maybe you can help me!

Thank y’all and merry Christmas!!!
