Double pawl magnetic ratchet

[DreamThinkBuild]

Hi All,

Here is another half baked idea of using a double pawl magnetic ratchet setup to drive a wheel.

Hi DreamThinkBuild,

You have a clever idea, perhaps other members here can come up with issues why it could not work, I like it. 

The rpm of the wheel would be rather low but this is not a serious drawback of course.  The number of teeth for the wheel and the strength of the repelling magnets should be found experimentally to have the least unwanted interaction between the moving magnet fixed on the arm of the rachet and the magnet which is the right hand side neighbour of the (just repelled) embedded magnet in the wheel.   Friction of the rachet magnets should also be minimized on the slope side of the teeth.

Any hope for a build attempt?

This one really caught my eye. Add a pendulum and or spring it could be interesting. too busy for any building right now though.
Good luck

Question is : do you have resources to build your ideas ?

Hi Gyulasun,

This will take a lot of experimenting to get right. Shorter teeth might be needed or the lever magnet may just float instead of actually pushing. Friction can be minimized by making the pawls curved so there is less surface area. I'm already doing some rough tests to see how feasible it is.

Hi Gdez,

A light spring might be needed to avoid a floating magnet situation. The pendulum idea could work also. Thanks.

Hi Forest,

I have magnets and 3D printer. Should have some more time this weekend to experiment.
