STEORN DEMO LIVE & STREAM in Dublin, December 15th, 10 AM

@callanan,

My I humbly ask what core material you use in your toroids?

Edit: Are you sure that the right most diode in your drawing is the right way?

Alex.

Hi Ossie,

That circuit is so good, it's bad.....MOST excellent.  Get you a good Hall effect in there and stand back!!!!!

Hi Ben,

Thanks. I intend on getting a hall effect switch to compare to the reed switch. The reason the reed switch is working so well is because I can angle it and control the distance easily which in turn controls the timing but more importantly, the pulse width. I should be able to do this with a hall effect switch also so it will be interesting to see if it gives me just as much control to compare it.

Until people build their own motor, they won't realise just how precise the positioning and pulse width has to be for the trigger. The higher the RPMs the more delicate this becomes and most people who build this motor will simply roughly just place the switch in a position to make it run with no regard for the pulse width if they can get it to run at all. It is NOT an easy motor to get to run and the switching point is very fine and delicate and related to RPM. So it WILL use more power input then it has too if this is not considered and done. But precise active switching timing and pulse width adjustment of this motor gives a 100 times increase in efficiency from what I am seeing!

Regards,

Ossie

Way to go Ossie!  Can you manage to get that baby running on 1.2 volts by any chance?  Not that it is important with as well as yours is performing.  Just curious if your setup can duplicate Steorns low voltage...

Thanks @Reincarnate,
Unfortunately, the video wasn't of much help. What was it supposed to demonstrate didn't come across at all.


As for this:

If that's the case then Thane Heins' is quite different from Orbo because the pulse motor as well as the toroids are the most substantial part of Orbo. If I find our what Thane Heins' device really is I may probably revise the above conclusion but thevideo definitely didn't help one bit in understanding its principle of action.

Omnibus, I suggest you dig a little deeper and do your own research... There are 40 videos on his youtube page and you didn't watch them in that short amount of time.

Next he used the username crankypants here at overunity and if you do a search for that username, you only get two hits even though he made hundreds of posts. I can't explain that but maybe you can PM him and he can.

He works with others that use this web site such as gotoluc and maybe he can illuminate you.

The fact is, you are looking at the same base process once you see and understand what they have in common.

Good luck

lol, I know what you mean.  I'm in the same boat.  I used simple ferite toroid I got in a multipack at radioshack.  I ended up with the same results as you.  I'm winding up a steel bushing now to see if the much lower permeability of steel will help or hinder this thing.  I'm beginning to wonder if Steorn made their own cores... Maybe magnetite or something. 1200 rpms out of D cell still seems out of reach with what we know so far, so something is still a mystery.

Hi CP,

I have tried winding a coil on a steel washer but it was no good. But in regard to what you and GL are trying with your attempts on ferrite cores, it is likely that you have had a motor that will work but did not realise it. The best test I have found is to simply energise the coil next to a rotor magnet in the still rotor and see if it moves. If not, rock the rotor slighly and pulse the coil and see if you can increase the movement like swinging on a swing. Ben mentioned this in his early posts and I agree that it is the best method I have tried to know if you coil can dirve the motor.

If your coil does this then it WILL drive the rotor. All you need to do is find the sweet spot with the reed switch or hall sensor and sometime you need to give it a good twist with your hand if your coils are not that good.

Regards,

Ossie
