take a look at the piston on steam generator if you want less wear and tear its simple yet effectiveThat's not related to this device, Gaz
I'm simply asking you to examine the drawing and comment on it intelligently.
If you build it without the swash cylinder, you’ll get some interesting twitching from the lever arms, but with it, won’t you need to build in some sort of timing, so you don’t get an ‘in’ stroke when you need an ‘out’, and vice versa?Oh, certainly energy will need to be put in to turn the rotor. The device won't run itself (not in this form anyway).
Well, I am rather pleased with the swash cylinder. It is a simple way to restrict the movement of the levers so the magnets don't crash into the rotor and swash plates have long been used for power transmission. It elegantly converts reciprocal motion into rotary motion. Of course any aspect of this could be redesigned but this is simple and easy to understand.If you build it without the swash cylinder, you’ll get some interesting twitching from the lever arms, but with it, won’t you need to build in some sort of timing, so you don’t get an ‘in’ stroke when you need an ‘out’, and vice versa?
What are you going to call it - variable reluctance isolated dual lever arm swash rotor transmission?
No, that's a fine contribution, @Hotstuff. I'm kinda hoping someone with a knowledge of esoteric electric motors will jump in and say something like, "oh, that's how such and such motor works." and go on to explain the inductance drag, kinda thing.What a brilliant thread; it reminds me of a tv show back in the late 70’s “It’s patently obvious”.
This looks very similar to the magnetic resistance system on my spin bike.
As the magnets are drawn closer to the disc/flywheel, it has a braking effect without making any physical contact.
The Swash drum seems to be a clever system to split one rotational movement into two opposing linear forces.
I hope I’ve not just stated the screamingly obvious and you were looking for something more.
Actually, in this configuration the swash cylinder is combining two reciprocal motions into a rotating motion.What a brilliant thread; it reminds me of a tv show back in the late 70’s “It’s patently obvious”.

No workshop and it's raining for the next week but I'm tempted to wander down to FabLab.Im up for it, get it built!
Nothing new there...That's not related to this device, Gaz
A 'push me, pull you'...?What are you going to call it
if you had a metal shaper machine you might agree with meNothing new there...
@gaz1, I'm not asking for improvements to the design. Rather I am hoping for suggestions as to how the inductive drag on the disc relates to the power output of the system. We can optimise the design later, if it proves interesting but for now the design is simply for the purpose of demonstrating what I'm talking about.if you had a metal shaper machine you might agree with me
the way hes doing it will push the slide bars outward as it closes like a scissor jack
the shaper uses a motor to a wheel and moves a slide bar connected to a push rod to slide the bar back and forth
this video show the ram slides and stroke of the shaper
whilst this annimation shows the wheel and crank arm moving to slide the ram
its the crank arm connected to the slide bar that pushes the ram head forward and reverse
it can be done with 2 crank arms connected too 2 slide arms that
Ive fields full of them!A 'push me, pull you'...?
That's yet to be determined, @Morris. First I'd like to get to grips with how energy is conserved in the system and once I have a handle on that I can look at what's optimal in terms of disc geometry and magnet layout.How big are the gaps between the rotor and magnets? Magnetism follows a square law so efficiency will be poor with anything other than minimal clearance.
The mechanical drag is too great
