Motor Stopped Working After A Few Uses
#1
I have a motor with nothing connected to it.  The motor is cheap and was probably not made very well.  During testing I ran the motor for 1 minute or less, then the next time it ran for a half second, then the next time it ran for a quarter of a second, and now it does not run at all.  I switched out the motor and confirmed that a different motor with different wires works with the rest of the hardware.

The motor seemed to "slowly get tired and die" but I don't think that is possible, especially after such a short life. 
1) What happened to the motor?
2) Did the + and - wires connected to it touch and kill the motor forever?
3) Can I fix the motor and reuse it in a later project?

What has to do your motor in a tinker board forum ?
Light blue words might be a link. Have you try to click on them? Big Grin

omg now no one else is going to answer!  lol Big Grin

The motor is connected to the board so I wanted to know if the board is burning out the motor or something.

@im4tinker if you have a better idea of a forum to ask this question, I will definitely move it there.

if you know a better forum for me to ask this question than I willl ask there instead, I thought this was the right place to ask.

Presumably an electronics forum.
Anyways the power you may take from the GPIO, is about 12 mA x 3.3 V = 40 mW (at its best). Better you show some picture of your wiring and details about the motor.
I wish you still have the GPIOs in a working conditions, because they weren't designed to drive inductive load, I presume.

You need to have the GPIO drive a larger transistor or a MOSFET that can handle the power and also you need a freewheeling (flyback) diode. Google around and you will find a schematic. Hopefully you didn't fry the IO.

In some of my posts there are discussions about to drive a fan, so it might be the closest condition applicable here.

yeah that was it, thanks, I just needed a new power source. It seems obvious and usually I do use an external power source, but I thought on this project I could skip that because the motor is small but I was wrong. Anyway, thanks again
