Hi, can someone help me interpret simply what the @4.5VDC, 70mA means? There is another motor but is has @4.5VDC, 320mA. I am guessing the 4.5VDC is the operating voltage for the motor and is the amps the amount of currents it will need to get to the no load speed?
so the 70mA essentially is a better motor than the 320mA one since it require less current but get you more speed also?
and I am a newbie. I am following the inventor guide and it has circuit#12 describe as using a transistor as a switch and that has collector current of 1A so it should not be a problem I think. But if I am using a transistor that only has max collector current of 200mA should this still drive the 320mA motor?
Can someone help me understand this?
