Really important question about motor
 

Hello, I have a question about a brushless outrunner. Here it is:
18-11 2000kv Micro Brushless Outrunner (10g) from hobbyking
I was building my mini quadcopter when I accidently broke one of the wires that were soldered with another wire, the one of the 3 important wires that we usually connect to ESC. So ye, in total there was 4 wires, but just 2 together.
Anyways, what I tried to do is solder back two wires together and put thermo tube over them. After that soldered the connections again and connected to ESC and after to LiPo battery.
What I heard was normal beeping like usual.. continues beeping ( 2 second interval ) , so everything like usual, then I even managed to enter the programming mode so I thought everything was okey but I was wrong.
After calibrating the motor again, I turned the throttle up and the motor started shaking and then spinning but really slowly and making too much noise like it was trying to spin at maximum but couldnt, and then I saw a little bit of smoke and I instantly turned everything off. I smelled like something was fried but not sure if it was the motor or something else because after trying to connect again, It Actually entered Programming mode again like usual. Is there any chance the motor is still alive and I can resolder it? I really hate this small copper wires, they break really easly.
By the way what happens if the wire of the motor breaks really near the motor ( like almost inside ), can it be fixed too because I am afraid another one is going to break.

Those wires are actually part of the windings and can't be repaired.
