brushless motor is stopped working !??! help plz
 

so i have a brushless motor and it just stopped working today. have no idea why .

its not dirty. not abused. worked last night. and kind of today. and now it wont work

its not the esc, my sidewinder worked fine in his car which is the same BL motor.

not the radio. my radio works fine with his ESC/BL motor

my servo is glich free



also when i give it throttle it wont spin . it just pulses forward then spins backwards every time i give it throttle . it like vibrates , it wont spin constantly in one direction but forward then back really quick (like it spins one way then back every .01second . probably not even 1 RPM yet ..the more throttle i give it it pulses harder and faster.

its never been abused . and sand never got into it .

the motor beep sounds sound diffent now, and the motor and ESC gets warm in like 30 second.


is my motor shorting its self out ? esc gets like 90 degrees warm after like 10 sec same with motor and the wires are warm too .
and in my lil bros car after like 10 sec of actually spinning at high rpms its still is pretty cold same with ESC

the BL motor is no brand off ebay. this is the 3rd one and the 1st 2 motors worked fine, so did this one until today.

it looks like you overheated it, try your motor on someone else's esc and see if it works, if it doesnt I dont think its worth fixing, try a new rotor. or you can just get a new motor for a little more money than a rotor.

Let us know how it works out!:tire:

I agree that motor is likely toast. Definitely try it on another esc to make sure though. You can get one of those cheap motors off ebay though and they work better than you might think.

but its only been ran like 5 times !

and it doesnt work on other escs

same thing

i've heard it's not good for a brushless motor to be run without anything attached to it. it can be bad.

i know that . cause you can overrev it

but it wasnt working in the car so thats why i toook it out ,.

did you open it up and see if the rotor was cracked?
