No, your DC starter motor doesn't "take what it wants," it uses what it's given. You can actually vary the speed of a DC motor by just using a large enough potentiometer. In that case, the motor doesn't say "Oh, I see you've turned up the potentiometer but I'm still going to rip more current through it and spin at top speed anyway." (And the torque of a DC motor is also proportional to the current that it's drawing.) |
