Title: motor burnt Post by: nikhiljog on December 07, 2013, 05:27:19 PM hi everyone,
I've used Turnigy 2209 28turn 1050kv 15A Outrunner for my quadcopter with 20A esc, kk 5.5 board, Flysky FS-6TB tx rx kit n 400mAh 40C battery.. a wire of one of the motors which was connected to power distribution board came off and the motor on the opposite end of this motor got fried... initially it was fluctuating in clockwise n counterclockwise direction n after a few second i observed white smoke.. Smelled real bad.. I saw that windings on 4 poles were burnt.. what might be the reason for the motor to burn? ??? ??? ???
