![]() ![]() in the middle is essentially an element parallel to the inductor load, but I really don't see the logic behind the ones attached to the motor shell. I'm not sure why these guys decided to use capacitors in this way. Though, according to other articles, diodes are popularly used. [edit: Stephen brought this to my attention. So if you suddenly apply a current via turning on a switch leading to an inductor, the difference between the on and off state in the current occurs nearly instantaneously, therefore it's like dividing by 0, and thus the voltage theoretically approaches infinity. Except that "inductive loads" are weird, and follow a v = L*(d/dt)*q relation. I'm not really good with electronics, so my best bet is to refer to wiki for any reasonable answers. ![]() Mathematically, it means asymptotes on a voltage-current graph. Not sure how the math works on that, but it might have something to do with damping out the voltage spikes that come from a V-i graph of an inductor (direct current motors are essentially inductors spinning a magnet), and there's always that spark that occurs when you simply attach a hot wire to it. ![]() Though, I did learn that some people like to solder capacitors onto the shell of DC motors. That pump (which, I do have photos of*) for the liquid dispenser has mass flux zero. The LED's have zero omega (translation, not spinning). I've been putting a lot of projects on hold lately. ![]()
