Has anyone seen Lasersabers new motor runs on 1000uf cap

Nice motor but I've been down this rd b4.  It leads to slow rundown times but never ou.   I hate to be a skeptic but the thing aint gonna work in selfrun or selfloop mode.  Even the Lutech motor can never self loop even tho it appears to put out more energy than it consumes.  The reason why is because the output measurements are all incorrect as the wrong equipment is used to measure the current which is pulsed.

Hi Oscar, I assume you're referring to LaserSaber's motor ? If so I agree. I shouldn't need to ask and it's my own fault for posting about my motor in someone else's thread. I just wanted to show that almost any setup can take a long time to run down if it's setup to do so. Sometimes it's difficult to know if a claim of extra energy has been made or not. I'm not sure that's been claimed here. LaserSabers setup sure is neat though.

My own goals is not to self run or make OU, it's just to design and build a motor to take advantage of the charging circuit ect. I first thought it was obvious enough not to need it's own thread but I think it might. I didn't mean to go off topic. My apologies.

Cheers

I really wish I could build my own to play with. If I build with #27 wire (all I've got) it will be massive !

27awg is 4 times the diameter of 42awg. If Lasers coils are 1/2 in dia, then the 27awg would be near 2in in dia, but thats only for the same number of turns. Havnt looked up the resistance differences,will be digging in this afternoon, but I think 42awg will be more than 4 times the resistance of the 27awg. Would have to look that up. But from what I imagine, it could be near 16-20 times difference considering the square area of the two, or to say the 27 has much greater volume of copper than just 4 times.

So to be in the same ballpark, yea, it would be massive. But it would be somthin to see, thats for sure.       One thing about building bigger, its much easier to get accuracy in the build.

Im working out a design that will use more smaller coils. If you have read my analogy of  audio speakers and motors, I think more is better when it comes to efficiency.

1 speaker     100w    100db       But 2 speakers    100w(total 50w each)  103db

4 speakers    100w(tot 25w each)  106db       And so on.

Hi Conrad,

That is a very nice build.

Hi Wattsup,

There are some alternative open source 3D modeling tools.

FreeCad is coming along pretty nice.
http://www.freecadweb.org

Blender has a steep learning curve on the GUI but is feature rich once figured out.
http://www.blender.org/

OpenSCAD for a more coded parametric design.

Wings 3D Is good for mesh editing

Meshlab is good for cleaning/repairing a final mesh.

Here's a list of some more free modelers

Made a mistake in the difference in wire. 30awg is 4 times the dia of 42 awg. I had that number in my head from the other day when I made that comparison. The 27awg is near 6 times the diameter.  So massive is a good word for it.
