Working Magnetic Motor on you tube??

[FunkyJive]

I wonder if these slight discrepancies would lead to the 45g difference between my 303g rotor (HDPE + magnets + two bearings) and the required 258g rotor of the original. Don?t know what the density of HDPE is.

Hi Omnibus.

If I'm sufficiently awake to do the math correctly (almost 2am UK time !), the increased dimensions of your rotor would add a mere 6% to the total weight - though this only being the case if you were comparing like-for-like of HDPE alone. In such a case the extra dimensions over Jason's would only bring it to a tad over 274g.

However, as there are added weights of the bearings and magnets in both cases then the weight contribution of the added HDPE material becomes even less (HDPE clearly being lighter than that of the bearings and magnets), so the extra dimensions certainly don't appear to be the main contributor to the significant weight difference.


All the best,

I wish more details were known about the Lego motor: http://youtube.com/watch?v=wcy0tedYBMg which is the best example so far for the application of the principle at hand, especially its self-starting, aside from the acceleration seen in the video. We have to work with what we have, however, and should only hope that the Mike story (wetting everybody's appetite followed by a sudden disappearance) from that unfortunate Bedini window motor thread won't repeat itself.

@ Omni

I agree 100%.  Althought it's been called a fake, I'm not aware of any replication attempts.

The Lego parts are readily available and all dimensions can be obtained from the video, since the lego blocks have documented features.

I am seriously thinking about attempting replication -- just to see what the true response is.   

Cheers,

@YADA,

yada, yada, yada,

to attempt a replication you must have all of the parameters, otherwise you will be trapped into the same loop as the asetelokin replicators that do not have a clue as to what they are replicating, but religiously stand their ground.  but good luck in your attempts, because if you do attempt you might be the first to actually have something of Merritt!

Do a frame by frame on that Lego motor and you can easily tell it is a fake.... unfortunately.

For the record, the eight magnets weigh 24g in all and the bearings are approx. 3g. Thus, had I had the right dimensions my rotor would've weighed 301g rather than 303g as it is weighing now.
