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

[scotty1]

Hey guy's.
I'm sitting here on my X-mas break with nothing to do so I made a clip to demonstrate a few things about the Steorn motor.
It's mostly for people who find it difficult to visualise.
I used a magnetic needle and iron filings to show how the domains act during the motor operation.

Happy New Year to all.
Cheers.
Scotty.

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

Hi Vince,

Wow! Great stuff! Very ingenuitive to do this with old parts you had lying around!!!

Absolutely first rate, looks like a deflection coil to me from my ol TV repair days 30 years ago! but hell it is a huge toroid no matter what!!!!!  If you could dig up one for each magnet, series them, it would run like heck!!!!!  Again EXCELLENT WORK!!!!!

Hi All,

Please see the following video. I have managed to now implement electronic triggering/switching on my 4 coil test motor and it now runs very stable without the need for tuning. I have also got a higher resolution ammeter for the current measurement. Enjoy.

The circuit I am now using is in the diagram below. There is no longer anymore need for power transistors for switching because of the low input power requirements of this motor.
