Mostly Permanent Magnet Motor with minimal Input Power

[gotoluc]

Gotoluc,


I like what you are doing, I love pinch fields, that is what I call it when you have the same poles facing each other like that.


I hate crankshafts, they are not efficient and so I made for myself a mechanical rectifier that is much more efficient and works wonderful with a solenoid input.


There are bidirectional solenoids that work in a similar, but not the same fashion, they have a core and a magnet out at the end of the coil, supply the power one way and it pulls the core in, the other way and it pushes it out, similar but not the same as yours.

Hi Tom,

thanks for your post.

I also hate a crankshaft!  please share how your alternative works

Thanks for sharing

Hi Luc,

Very inventive design, thanks for sharing. The weight of the coil moving back and forth at low speed would be good for a lever/pendulum setup.

This design I used a small motor with weight.

But if you place your motor centered on top it can use the displacement of the coil instead of a spinning weight. That would eliminate some side to side frame wobble and the powered side dead zones. Then lever through lenz with a big block N52 on the bottom over some coils...

3 one way needle rollers, 3 gears, 3 shafts, 2  connecting arms and one of those is also the input arm.

Thanks Tom,

I now see how your system works.

So you think all these bearings and gears are more efficient then a crankshaft!... I would not of think so but since you built it I'll take your word on it.

Very interesting and thanks for sharing

Thanks DreamThinkBuild,

I had not seen that video. Thanks for sharing it.
You're right about there's no need to spin the weight around. Just back and forth would do it even better.
Since you have the build, pickup a 120 vac Solenoid, find a longer core rod that fits nice, add the magnets on each ends, use a DPDT relay switched by Hall effects to send the AC pulses and let us know how it works out.

This is a great idea to use this effect.

Slightly off topic, see you talking about an efficient way of extracting energy from reciprocating motion. Quite straight forward:

Makes you also wonder why we're still using gasoline engines that are at best 40%-50%, well makes average joe wonder not the average community member.
