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

[k4zep]

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.

Hi Scotty,

Thanks for the demo, very good!

Happy New Year,

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.

Ossie,

You just get it better and better.  Now you need a 100 ma meter so you could tune mechanically the coil placement, pickup etc. for min. current, you gotta have an old Simpson or Triplet VM around there somewhere!  Or at least an ol RS Analog VM.........Most excellent!!!!!

Hi All,

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

First - PN100 (not trigger transistor, the other one) collector reference to ground - negative.

Second - PN200 collector reference to positive.

Third - Across the toroid coils (all in series).

Fourth - Across the 1A ammeter.

@callanan,

Very impressive work you have done!

I can see the current usage in the video.
What is the input voltage?

Do you plan to try a output generator coil also?

Hi Alex,

Thanks. The input battery voltage is also shown on the multimeter in video and is just a tad over 12 volts....
