I’ve re-winded a (RC plane) bldc motor (1800KV, 12 pole, 16 magnets) with 26AWG wire 13 turns on each stator.

Before re-winding the motor was ok.

Now it doesn’t spin. Initialization with esc (and PWM) done properly (the tones of settings are as it should be).

But when I try to actually run the motor, it just shakes with high frequency beeps for few seconds and stops (seems it’s getting signal from ESC & trying to spin but can’t for some reason).

I’m using MCU (Atmega32) PWM signal (duty cycle controlled by a Pot(VR).

info: ESC(20A, non-branded) and Lipo battery(2s, Mystery 2800mAh).

Can anyone please help me?

note: I'm not using any remote control
Before re-winding it was delta now I re-winded it as star configaration.

Check
1-Short between wire turns
2-Wire not properly soldered to terminal
3-Wires not connected to the proper terminal
4- Does that ESC work with a Star winding

You do realize that will change the phase of everything?
