I'd noticed that for the small motors, the ones used in toy cars, there are rpm values and voltage values written on the specifications.
For example, I have a motor at a range of (12V - 24V) and rpm of (4600 - 9300) respectively.
Does this mean that I need to provide 12V to the toy car so that the wheels will rotate at 4600 rpm and 24V to rotate the wheels at 9300 rpm?
I would also like to know does the other way work? I mean if I were to use the motor as a generator.
Does this mean that if I were to provide 4600 rpm, I can generate 12V of voltage?
Any response is appreciated.
