You're not getting even close to 2 amps in there, let alone 10. As the other comment already said, the amps on your power supply are just a limit. The current passing through a wire is voltage divided by resistance of the conductor, and that resistance is static, but you turn the voltage higher, which does result in higher current, but it is quite low. Higher resistance - less current, Higher voltage - more current.

I am glad to see someone else caught this. Saw a similar issue with video where someone was testing fuses, he actually bought load resistors so he could test them "at the correct voltage" without realizing that there is no difference to the fuse, amperage is amperage, it doesn't really care how much voltage the rest of the circuit is dropping.

@@malanikuiper414 The simplest explanation is to look at OHMs law; if you put a voltage across a resistance, current flows according to the ratio between them. In order to change the current you must change the voltage. So in order to limit current, you limit voltage. So a power supply will attempt to provide its Max voltage up to its Max current, if the load would draw more than Max current, then voltage is reduced until the draw is max current. If the max current is greater than the load, then it raises to max voltage, but can go no higher. Think of it like a hose, you can bend it to reduce the flow, but once its full open, its full open and you can't open it any more to get more flow.

Right on the money. Although it's also worth saying the power supply is reporting the *average* current. I'm sure there's a fairly large spike when the brushes first make contact and connect the circuit. You've got to take inductance into account so it won't just be V = IR at that point. Really you need an oscilloscope.

7:12 The two amps are only the limit. The actual current draw is around 110 milliamps. So even if you set it to 5 amps, it would be the exact same result. It's only the voltage that makes it go faster :)

you can do brushless dc motor, no commutators, no pulsing, just dc wire running over radially in circle over a ring magnet. high current thick wire replaces many loops of small current wire. yep car battery sized heavy duty current wire. wire? make it a beam, or thick metal rod. flexible metal strip running on a split current rod works as a commutator too. the strip friction makes contact with the spinner. thats wire edm cutter in action. lol. also friction will melt the wire.

You know, could've made the commutator with some thicker wires. You're not burning out the motor, you're snapping the very weak contacts due to abrasion. And raising the current limit on your power supply does not change the amount the motor draws. Also, why aren't you using another magnet? The coil that goes to the top doesn't do anything in your design. Could've made only one brush on the one side for higher efficiency, the other is just wasting power

After watching this, I realized a much more efficient and powerful design would use a little bit of logic, with a single SR latch. Instead of running the entire power through that tiny brush, use a voltage level signal with a series resistor to turn on and off an SR latch with an H bridge powering the motor. This will also prevent the motor from needing a kick-start. No more sparks, constant power, and avoids the unnecessary friction from large brushes

@@JamiesBrickJams On a normal brushed DC motor, the sparks occur because as the brush begins to touch the next pad, the motor draws an incredible amount of current through a very tiny contact area. With the brushes constantly in full contact and having it controlled electrically rather than physically, there would still be high currents when switching, but it's at least already making full contact and not vaporizing the brush due to the large surface area. Btw, I'm thinking of a high power DC motor here with maybe copper tape as a pad and carbon or brass brushes. Brass might be best for this use case

What if u divided each windings of a 100 lopes in the 5 lops of 20 so that you still have 100 lopes per each side but twist the 5 wires to make a thicker armature wire

I don't know why, but it seems like wery steampunk looking thing, while it's fully electric, it is an interesting effect of copper wire

Seems to me like you're just building a homemade motor, and the fact you're using Lego for the mechanical parts doesn't really much affect it's properties except for that plastic on plastic has relatively high friction compared to some of the other options out there. That said, good first concept. I'd suggest having more than just one string of wire where the brushes touch (loop it back and forth a dozen or so times?) since that seems to be a weakpoint, also might look into redesigning your "brushes" as well. As in... use more wires. Like in an actual brush. And then the next step would be completely redesigning that part of the assembly so you can put a little more constant force on the brushes, make the contact area bigger by using aluminium foil attached to a 'barrel'... those sorts of things. Looking forward to what you do next.
