Hi Low...this was my point also... how he plan to put energy in the system in order to make it run, and keep running.
How about your project ? Do you have a solution regarding on what your magnets run and what will hold the turning component ?

You don't get out of the fact that the machine has to generate more energy
than it loses *per each of its cycles* or it will simply spin down over time.
A sufficient flywheel is required to lift the weight once and keep the mechanism
from slowing too much when it does.

---

If one could lift/drop the V-bar electronically with a solenoid, stepper motor or
servo motor based on the angle of the wheel. To optimize the wheel's acceleration
profile- if any. It then would be fairly easy to;

a) calculate how much energy is required to match a wheel's magnet acceleration
profile relative to RPM's. This can be done with a string wrapped around the axle
with a weight hanging over the table edge on a pulley.

b) calculate how much energy is required to lift the V-bar. Using it's weight, gravity
constant and lifting distance, assuming one is going to throw this energy away.

With these two pieces of information one could see at a glance whether to go ahead
and build the cam lift mechanism. The cam can try to recover some energy from the
V-bar drop or not, based in wheel rpm.

I'd feel a lot better at knowing analytically if one is generating sufficient energy
magnetically rather than just building something that may not work.

I feel the same way but what you're proposing isn't an analytical solution but experiments more complex than just building the cam and trying it.

Yes, It was a joke that I should not do! I apologize to you and all your friends who have lost time in commenting on ....

The device had to operate the magnet inside a coil that I had in my shirt. Greeting, Robert"

lol get the f outta here. that explanation makes less sense, and i think i'd rather see someone actually do that rather than see a magnet motor. in his shirt?  under the table would have been more reasonable. hey Mylow i know youre watching this thread too its time to chime in


at first i thought the spring was the secret.. and it would degrade over time.. but looking again the timing is off, the spring does nothing but protect the top bar from damaging over time.. the key to his arrangement is the imbalance.. his rotor is clearly NOT balanced and he has set a heavy point in one spot, exactly where the 4 magnets line up rather than just two. also the plastic slider is weighted in the same spot.. this is genius because hes actually using gravity and the magnets at the same time.. you cant run a load in this setup if its large enough to mess up the "unbalance".
also anyone who has played with pulse motors religiously may have noticed that sometimes the wheel goes faster when you "cog" it in the right places.

it seems to me that i think Bruce or something mentioned the plastic thing being used to pass the hump and hes right, but its not just the magnets, its the initial momentum gained from the rotor wanting to fall in the right direction. the motion and cogging should be equal until you bring the extra momentum into the picture hes generating from the rotor imbalance.


then again theres the chance i should have read the whole thread and i missed something important

Longer the cam is, more work must be done in order to move. Think at disc break on the car...bigger is, less friction you need to break. Make it shorter...you need 2 cm up-down on magnet... shorter the arm is, less you spend. Make a 2 cm bump on the axis and an arm from top to the bump

I am doing some work on a related project and even though the cam is important, it cannot work! All the work gained in pulling the magnets closer will always take the same work to pull them away again. If there was enough energy to push the attracting magnet away, then the rotor would already have enough energy to pull itself away.

The rotor only has two magnets, the two in the center of the start of the "V" track. The rest are steel. The bar stator magnet on top, is magnetized through the faces and not end to end. This is an entirely different type of operation.
Is this possible?

   

I was planning on building one of these myself at some point, but right now I'm pretty lacking in materials & tools to work with, so hopefully one of you can try this yourselves.

I thought of using two bar magnets as a lever escapement so that as one magnet gets repelled from the 'speed bump' the magnet on other end of the lever gets pushed towards the v-gate, accelerating the rotor until it does the same. It wouldn't be physically touching the rotor of course, but hopefully you get the gist of the idea.
