Hi Ossi,
many thanks for the additional infos
with the imperfect coil´s induction.

Could you please try this circuit and let us now the charge rate of the cap ?

Maybe you can make an additional video and show the voltage and
also use friction on the rotor manually and show, that the input current does not increase ?
Many thanks in advance.

Regards, Stefan.

BTW, I had the idea of flipping the entire setup seen in my video upside down and using the wood base as the part that spins and contains the magnets. So the harddrive metal discs would be the base.  Of course I would use a smaller base, as that one is a bit large, but the wooden base should extend beyond the metal discs to get the magnets away to minimize eddy currents.

... Awe what the heck, why not remove the bearings and do away with the metal disc completely? Has anyone ever tried to remove the bearings from the harddrive?

Thanks for the helpful info. Is there a way of making those wooden circles with just an ordinary table saw and drill press?

Yeah, actually you can cut circles with a table saw, although I have not had to do it. There are some good video's online that show you how to.  It's pretty straight forward... Here's one... http://www.videojug.com/film/how-to-cut-a-circle-on-a-table-saw-2

I was lucky enough to find a scroll saw at a pawn shop for $20, so that's what I use.  You may check your local pawn shops, you never know what other peoples junk will work very well for your projects.

Hi Stefan and All,

Here is a load test video as requested. The description is as follows:

"The test in this motor shows the lack of an increase in input current when the rotor is placed under a load. The generator coil and lamp which is 12V, 100ma, is by no means efficient in design but purely used to represent a load only and not an attempt to effeciently extract electrical energy from the rotor. Any apparent increase in input current that you may perceive is due to the increase of the duty cycle cause by the reed switch being turned on for a longer period as the magnets pass by at low RPMs."

A fixed reed switch was used as the trigger in this video so output power was not optimal. I am still working on better trigger and switching methods for optimisation and functionality.

In regard to the cap charging test, I may do this at some stage but I am really not interested in it and don't see much point. Such a test is better suited to a Bedini motor or something designed to charge caps but I do not believe that this motor is designed to do this or will be any good at it...

Ossie

Ossie,

Your message in the video, "Coils are cold to the touch!" made my day! 

Hi PL,

Looking at the low current the motor is drawing, I don't think it means anything special at this stage. It just means that resistive heating is being kept to a minimal....

Ossie

Hi All,

Please see this video of my Steorn test motor running on a virtually dead 9V battery.

http://www.youtube.com/watch?v=H-W4WU6t8W8

This was just to show some people that this motor can run on very low levels of input power and not need power supplies, large lead acid batteries or even "D" cell batteries for it's input power.

Ossie

Hi All,

I have just mounted an additional two coils on my Steorn test motor platform for a maximum of 4 toroidal drive coils and I thought it important to show other motor replicators out there the importance of the cogging effect that your motor should have. Please see the following video.

http://www.youtube.com/watch?v=5ZdNEb2aCd4

According to the theory, the motor will gain energy from the rotor magnets attraction to the toroidal coil's cores. So to magnify or take most advantage of this, you want your rotor to be in attraction mode, ideally, 100% of the time through one revolution. In reality I have managed to get it to be about 95% of the time as can be seen in the video but this is very important for this motor and something you need to take into account when designing your motor for the best efficiency you can manage.

When you do this, your motor will have a very pronounced and strong cogging effect at very low RPMs such that even when the magnets are a considerable distance from the coils they will still have a strong enough attraction to pull the rotor towards them.

A perfectly designed rotor in regard to this will be one where it is very difficult to position the rotor such that it doesn't not pull itself towards the coils.

Regards,

Ossie
