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

For those of you that want to try and make an orbo but do not have the resources maybe mine will inspire you to use what you can easily obtain. 

I took the focus toroid coil from an old CRT and mounted my magnets by attraction only to a bicycle wheel. I can get more rpm by adding more magnets but it seems to run just fine with 4 and 1 toroid.
Mine is running at about 50 rpm, on 12volts. the reading jumps between .02 and .11 on the mamp scale .  The toroid shows a voltage of 3 to 5 volts across the terminals. It's got a surprising amount of torque for the rough and dirty configuration.  Ive held up a fully shorted 12volt coil to simulate a generator coil on the opposite side and the rpm or the current draw is not affected at all. I can feel the magnets attract the coil as they pass but it purrs along quite nicely.

To make it I used;
12 inch STEEL bicycle wheel, no tire
1 focus toroid coil from a CRT tube
4 ceramic magnets 1" x 2" x 3/8" Fit inside the rim by magnetic attraction only
reed switch from a door alarm
npn transistor switch any kind
12volt, 6 amp battery charger power source

I love it!  That's exactly what people need to see.  You don't have to have everything perfect, all you need is to find a way to get some hands on experience with what you've got!  I know I have made some motors that looked like a hunk of crap, but that's how you learn!  Thanks for sharing.

@callanan,

Excellent modification. Can you now compare the current and voltage scope traces when the rotor is removed with the current and voltage scope traces in the presence of motor turning?

Great work Ossie, makes me want to get more time to get mine done!  Been tough with so many work hours right now, but it's great to keep checking in here and seeing so much progress from everyone!  Even if all this work does not eventually prove OU, we have all definitely learned a whole new concept of a pulse motor!

Hi All,

Here are some scope traces of the motor running at about 1000 RPM.

Hi Ossie,

I cant help but notice your circuit is almost identical to Bedinis patent, namely the half sequential switch. Hall triggered or trigger coiled, it has that familiar PNP isolating a drive coil which is darlingtoned triggered. It would only be a short step forward before you switch on both polarities, using the full sequential switch, either with a separate hall trigger for each polarity or a extra trigger coil/winding.

All that would be required is a second circuit built identical to the first and inverted over the drive coil. Just like the full window motor circuit in which others have drawn tangents from. Oh and of course one would most likely need to add a full bridge rectifier.

Good to see people are finally waking up to these ideas.

Good work

Regards

Attention, Vince, the coils from CRT toroids are not wound around the toroid. For the main part they are mounted against the internal wall. They focus the magnetic field in the center of the toroid in order to deviate the electronic beam. Thus the magnetic flux is outside of the ferrite and not along circles inside the toroid. Inversely this explains why you got a high voltage (3-5v) due to the motion of the rotor magnets. Your experiment is not at all the same as in Steorn device where the magnetic flux from the coil is (supposedly) confined in the toroid.
