Thane, just got the rotor before I left, currently in an internet cafe (without the cafe) in Queenstown.

Anyway it seems 6 of the magnets escaped the packaging, ideally you could send me more, otherwise what size are they, the 1 inch seems right from memory but as I don't have it here I'm not sure.

When you ran this rotor you sent me with just the 6 magnets how many coils did you use to get the acceleration, just one?
If so some specs could be good, I wound a bunch but suspect all are too small.

And do you recall or have any record of the RPM needed to get the effect with this rotor? (3 times higher than in the videos due to 1/3rd the number of magnets?)

Thanks.

Hi Aether22,

I can believe that they escaped. Allready got a blood blister from the two magnets I received. In my first order, I got confused with their statement and ordered a 1" magnet set where they specified six pieces. The six pieces are two magnets, two cups and two washers. If you got the Ten inch 6 spoke wheel, you need to order three 1" magnet sets to get everything for the wheel. Anyway, they are packed in a plastic container and would have a hard time escaping. Just be careful when you place them in the cup (N-S), because they cannot be removed without slicing the edge of the cup.

Hi Thane,

All my ordered parts will be here soon, so I'd like to focus on building the best cores. I've seen your recent coil recommendations.

Can you give any recommendation on core size, length, face shape?

SAME SHAPE SAME SIZE AS MAGNET - BEST SHAPE IS A C SHAPE CORE / COIL THAT EXTENDS FROM ONE NORTH POLE MAGNET TO ANOTHER SOUTH ON THE ROTOR.

Is your laminations, grain oriented silicon steel or Home Depot steel pieces?

WE USED BOTH - BUT GRAIN ORIENTED SILICON PROVIDES THE LEAST HYSTERISIS DRAG
HOME DEPOT STUFF IS JUST FASTER AND EASIER TO MANIPULATE..

Do you have any opinion on why Vince's setup only worked with one long core, instead of the 8 short ones?

I DIDN'T SEE AND PHOTOS SO I CAN'T COMMENT.

In the latest pictures, the gap between cores and magnet seems to be about 10 MM as opposed to the less then .5 MM in a regular motor or generator. Is this part of the requirement to get the motor to accelerate?

SORT OF - IT IS TO REDUCE COGGING TORQUE SO THE MOTOR CAN GET ITSELF UP TO A DECENT SPEED (ABOVE THE MINIMUN CRITICAL SPEED AS VINCE CALLS IT). THE COILS CAN BE MOVED IN CLOSER AS THE SPEED INCREASES IF DESIRED.

Thanks,
Larry

I HOPE YOU ARE HAVING OR HAD A GOOD VACATION.

Anyway it seems 6 of the magnets escaped the packaging, ideally you could send me more, otherwise what size are they, the 1 inch seems right from memory but as I don't have it here I'm not sure.

THEY ARE 1" FROM LEE VALLEY - I SENT YOU 18 MAGNETS - 6 x 2 ON THE ROTOR + 6 MORE IN A PLASTIC CONTAINER WHICH SHOULD HAVE BEEN STUCK TO SOMETHING INSIDE THE BOX LIKE THE ROTOR OR THE ARBOUR?

When you ran this rotor you sent me with just the 6 magnets how many coils did you use to get the
acceleration, just one?

JUST 1 - BUT THE MORE THE MERRIER.

If so some specs could be good, I wound a bunch but suspect all are too small.

SO MAKE THEM BIGGER - 200 ohms WORTH OF 26 GAUGE SHOULD WORK VERY WELL - VINCE AND COMMENTS? ALSO PERHAPS THIS PHENOMENON ONLY WORKS IN CANADA - WHICH WAY DOES YOUR MOTOR SPIN WHEN YOU PUT IT IN THE SINK?

And do you recall or have any record of the RPM needed to get the effect with this rotor? (3 times higher than in the videos due to 1/3rd the number of magnets?)

IT DEPENDS ON THE MOTOR AND OTHER FACTORS BUT OURS WILL START TO ACCELERATE AT 200 RPM.

Thanks.

Hi Thane,

How are you today?
Got a question here, the coil core ferro magnetic material. I'm dutch and my english could be better
Is that ferrite? Or is de wire wound around the U shaped metal bar?  Got all the parts and  except for this little thing

vibrovirii

DEAR VIBROVIRII

PB IS STILL SLEEPING SO I AM GOOD SO FAR.
YES FERRITE MATERIAL - U SHAPED CORE IS GREAT - TRY TO MAKE ONE END OF YOUR CORE CONTACT A NORTH POLE MAGNET ON THE ROTOR AND THE OTHER END A SOUTH POLE.

DUTCH PEOPLE ARE WONDERFUL - I MARRIED ONE.

Thane,

Thanks for the info.
