@ Clanzer   

Nice work... Looks like you have most of the Kinks worked out with the cam.   I am looking forward to seeing your replication with the stator magnets installed.

Take a look at Clanzer's latest video.

hi,

this is for you "mechanically inclined" to tell this "mechanically challenged" guy if he is right or wrong.

thanks!

tom

from the lack of replies, i guess i have a "communication challenge" too.  i think i see where it is.

the statement about adding a push rod.....
of course segment b has to be changed a bit.  it would really be a cam with a 1 unit rise (lobe).  the lobe would push the rod (as the shaft turned) which would then raise the stator magnet assy.  the dwell on the cam would dictate how long the assy. stayed raised, just as the height of the lobe would dictate how high.

the low point/s of this cam would be the shaft surface.  if the low point/s were 1 unit higher than the shaft, you would have a longer circumference.  of course now the high point would be 2 units from the shaft surface and make a 5 to 2 ratio.

anybody still on topic, please jump in.

tom

Tom,  it looks like your are on track with making use of better leverage.  The problem that I see with the cam being significanty closer to the shaft is that it makes it more difficult to make adjustments.
There may be other ways to use leverage.  I will see if I can make a mock-up and show you what I mean.

@tbird re cam . Here is my opinion . Suppose that due to the requirements of the system , the total lifting has to happen during 10degrees of shaft rotion . To achieve this with a smaller cam , the lobe or ramp on the cam needs to be much steeper and shorter . with the big cam the ramp is longer and less steep . The amount of work done is the same in both cases and happens in the same amount of time . Imagine biking up two hills . Both are 100 metres high . one is short and steep , the other is longer and more gradual . Both have to be climbed in the same length of time . The amount of work done is about the same in each case . That is my gut feeling .

OK here is my attempt to use a Leveraged Approach to solve the problem.   I am waiting on magnets... should be here by Friday.    Anyway,   there is a lever at the bottom to lift the stator arm on the right side.  It provides a little over 4 to 1 leverage.  The cam is on the wheels left side.  I know I need to make a better cam but I just wanted to show how I visioned a lever to do the lifting.   I moves the stator up about 5 to 6 mm but very easily.  I put a couple steel bearings on the stator to add some weight for testing .

I would certainly agree with the last test rig posted on here for a chance of success. I have thought the exact same principle. I would change one thing and add one thing. I would make the rotor much larger and I would add a weight on shaft to help momentum to get past the cam lift/sticky spot.

Good build, @maw2432. Waiting to see how it will behave with the magnets. Good luck to you too.

Thanks Omnibus,   

I was thinking that it may work better in repulsion mode.  Just need enough weight on the stator to keep it pushing the rotor until it gets to the sticky spot and then lift the stator with leverage.   This way I only use the weight of stator to be moved.  With attraction,  I need to move the combined force of attraction (at the greatest attraction time) and the weight of the stator.   Hard to make small adjustments with an attraction design.   With repulsion,  I may only need to add some weight on the stator to until it is enough to do the job.   Your thoughts?

It would be great if you can make it work in repulsion mode only but somehow it is not always possible to avoid attraction. Probably you saw on the previous page my rig's idea: http://www.overunity.com/index.php?topic=10034.msg269285#msg269285 . I would be curious to see how you're going to accomplish repulsion all the way.

nice build bill!!

first thing that comes to mind, does the L mount for stator magnet (part that goes up & down with magnet attached) tend to go up unlevel?  looks like with the play you have in the guides it would.  if you get to a point where this bothers you, you might shorten (left side)the segment where the magnet is (extend the left guide in as far as possible) and put that length/weight to the right of the push rod part so it looks more like a T than a L.  that should balance it better so it would go up without favoring one side.

i don't see a provision for the 2nd small magnet mounted on the base in Roobert33's machine.  it appears to me he has used a lever there too but instead of making it easier to lift, he has made it harder (segment the cam hits is shorter than segment magnet is mounted on).  maybe he needed it to move further away to do the designed job.  do you think it has a spring to keep it down or just uses gravity?  is it in attraction or repulsion?

lots to play with and think about.

neptune,

i think you forgot the 4 or 5 friends that will help you over the short steep hill.  maybe i'm wrong, but shouldn't we count them?

@tbird . I do A lot of biking ,and wether the hills are long or short , I get no help from any friends ! OK I know you did not mean that litterally . Work=force times distance , so if you lift the magnet a given distance , the work required remains the same . Think of me biking up a steep hill . If I use a lower gear , pedalling is easier , speed drops , and the climb takes longer . But I still burn the same number of calories .Gearing is just a continuous form of leverage . By the use of leverage in this machine , you could lessen the force needed to lift the magnet , but the lifting would need to happen over a longer time period .{more degrees of rotation] and this may upset the timing of the machine and would also extract the same amount of momentum from the rotating wheel . So, how about an opinion from some of you mathematicians instead of leaving it to an old retired truck driver like me.
