There is a very detailed thread on rewinding. Contains every detail. Please search it.
The motor wouldn't have been damaged by a simple fall. Motors are very robust. A ESC can't damage a motor at all. Have you checked for a broken connection using a multimeter ? (continuity feautre)

I have checked continuity and beep sound comes. This means continuity is okay.
kaante ne voltage regulator ki ek pin ko microcontroller se attached ho gaya tha...
isliye bol raha hu ... ki esc ne motor kharab kardi.

That motor is damaged too. Maybe some wires inside are shorting. Have you checked the ABC leads for a short?
You may have to tear the black Heatsink.

I asked you to check under the heatshrink if there is any short due to unwanted bending of wires.
If you don't find anything then better get a new motor.
They are dirt cheap anyways.

There is this person with handle @ rayofhope on this forum.
He had bought  BLDC motors, 30 amp Escs in wholesale to start a venture. Due to unforeseen circumstances, he can't continue that venture anymore.
He was selling the motors a lot cheaper than on the market. Buy from him.
