Hi
I am currently working on a hexacopter. After completing the assembly I tried to calibrate the motors. One of the motors didn't spin properly and smoke started coming from it. This happened twice. I don't know if the problem is with the motor or the ESC. I made sure all the wires are perfectly soldered and connected. Attached sleeves as well. I am really not sure where the problem came from. Would be great if someone could tell me where I went wrong. Btw, Im using T-motor 400kv and T-motor ESC 40A.
Thanks

Are those ESC's OPTO or do they have built in BEC?
There is no calibration or signal the pixhawk could send that would burn your escs. Do you have multiple bec power from escs in parallel?

i just got 2 motors burned at the same time, Tmotors and castle esc
Its got to do with calibration or signals, motors number 1 & 2
new...and defective.
All you need is one bad soldered gate signal on one FET to end up with DC being applied to a motor (that can admage it)
..or a incorrect winding or connection of leads from the motor - which also could damage esc ..
(This is a reason to start things first time on a lab PSU , or have other means of current limiting during test)
But the motors and the ESCs are brand new :/

you can try to use the esc with another motor.
- the burned motor is to be considered defective. (the insulacion between windings is most likely defective now)
