Thanks broli
I can assure you that it is everything else than easy

Extremely Nice!!

Good Luck

Hi Jetijs,

I am so happy that you are up with a new design again, I wish you the best.
I am eagerly following this thread. Your work is so neat as always.

Thanks guys

@jetijs,

I see what you were saying earlier about my motor design
I don't know how I got that mixed up. I will make changes and post a new drawing. Thanks jetijs!

Another update.
gluing coils on the stator poles was a little messy. I did not use the hot glue, because it cures too fast and does not hold the coils in place very good. Instead I used some drops of epoxy resin between the coils and stator poles. It was very hard to align the stator and rotor so that there was an equal air gap all around the stator. At these small air gap widths, if the stator is even a tinny littlr bit offcenter and still does not touch the stator, it will lock up if fired, because there is not equal attractin force from both sides. Also you can not fire only one coil leaving the opposite coil alone, because this will just lock the rotor still. Anyway, that part is done and I am glad, that this part is over
A few pictures:







Thanks,
Jetijs

Got an estimate from Protolam...
Total estimated cost = 500 USD
Material: M19 silicon steel laminate
Material thickness: .35mm
Total laminates for rotor/ stator: 108 (1.5 inches)
cost is about 3.00/laminate for rotor, 2.00/laminate for stator.
Not as cheap as I anticipated , but the results are still only preliminary. When I have the final draft of my motor, then I will have a better estimate.

[Jetijs]

Is that for the whole core set or just for the cout out laminations?

[Archer Newlun]

Timing Advance

How do I control the timing advance on this motor?

[Archer Newlun]

Jetijs,
That is for the laminations cut to the specs that you specify.
They price it on a per pound and/or per laminate basis.

Awesome Work

Jetijs,

Absolutely beautiful work. What an inspiration!

[Jetijs]

Thank you Peter
Your support means a lot to me!

Archer, you can use any timing device you want for this motor - reedswitches, optoswitches, hall switches or even carbon brush commutators/ It is up to you, what ever is easier for you to make

Wow Jetijs, what a motor!!! Im currently modifying my latest adams motor to a lindemann attraction type motor. All i have to do is make a special rotor and rewire my coils and it should work. If all goes well, i will be able to easily adjust the gap between my rotor and stator to get the closest coupling possible.

What a motor!!! It is marvelous, incredible work.

Thanks guys

Another update.
I finished the timing discs with adjustable ON time 10-70 degree of an ark.
Those long bolts are only temporary.
