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

It's the only one I've seen posted here. Let me know if you find another. Cool circuit.

He's talking about the bridge rectifier circuit Steorn is using. I have noticed that some people have missed this fact.

But Steorn has a simple generator on top of the Orbo motor which generates conventional AC which is rectified into DC and fed back into the battery. This is the mechanical energy capturing part.

The circuit I posted is just a way to recycle the inductive energy part of the toroids.

Steorn top circuit is probably simple since it's just rectifying from a the coil output, so they only need some low Vf schottky diodes.

Hi All,

Merry Xmas,  Stoern MOTOR ONLY replication is here:

It is the most basic drive I could build but it does work, it accelerates and there is NO measurable field around the toroid.

Nice. I wonder if Steorn's January demos will replace the relays with transistors.

Thanks Paul,

There is no reason not to use electronics package except that they are using such a low voltage source for drive motor but a small converter or piggyback front end power supply could fix the electronics package.

It is amazing what you learn (and I am still learning) when you build a motor.  Now to build a nice one!  Will take several weeks to get all parts together, do research on LV coils, etc. Cut plastic, bearings, etc etc etc.  But will build several more.  Probably take several try's to get it going right.

I wondered why I saw sparks on the video of their unit on the 1.5V battery, understand now.  There is a hell of an inductive kickback from the coils, diode takes care of that.

I couldn't have built it without all the input from the many people who post on this list, the videos, the pictures, TK's video. etc., and listening and watching and looking very carefully at what was there.  Nothing like hands on electronics for 55 years.

Merry Xmas, 

Ben
