Both rotate the same axis (1 is not enough due to the pressure that is being put on it, a spring mechanism stuff) With 12v it runs like a dream, till they burn! and from what I observed, always 1 motor hits higher temperature than the other, is there a problem with that?
Then I dropped it to 5v with diodes and the motors didnt have the strenght to start spinning, so I raised to 8v and they spin, not very smoothly (is that spell right?), but you know, they work, but still they're overheating!
If I used PWM to control both of the motors, would it work and not burn'em?
Thanks and sorry for the long and confusing text. Related
