New permanent magnet motor on youtube from Roobert33

[Arrow]

Thank you for the scale analysis drawing.

And the rotor width is somewhere between 2" - 2.5" with a diameter around 4".

You might want to try scaling his hand as compared to an average male hand and see what you come up with.
My index finger is about 80mm and my thumbnail is about 18mm.

Please, count motor scale by using with more technical staff as parts on the motor, Human body "parts" can no be the scaling basepoint if you dont know man personally and very close:)
Sorry Sir, human body can be small and/or large because of diffrent genetics
You are kindly asked to stop discussion about drawing scale, because only 1 man on the world can judge this scale true or not true  and it is Mr.Roobert33.Are we able to call him to this topic? Guess - NO:( I still counting that my drawing in the relevant - good scale to built such motor and run it.Mean time I am busy with this project very seriously to reproduce motor based on my drawings. Video materials about results will be shared here. I am 50, and dont have time to make mistakes:) Busy with motor construction already 10 years, and about 36 years in model aircraft construction from strech photo pictures.This motor will become good charger for my electric avia modles LiPo, LiFe ets batts at the field and mountains.
Thanks for your post, opinion and time. I really appreciate you, because you are recalling my English.
TO: Mr.Roobert33,
if you are reading this post - You Are VERY MUCH Brilliant Engineer Sir! It was grate to see your motor as the result of your many years research! Thank you Sir for such GIFT to PEOPLE of ARMENIA and to world to make it GREEN!
As the RC pilot I want to see in the air nature Eagles flying free in clean AIR!

Truly,
Rob

Just thought I would go ahead and post a couple images of my progress. (see attached)

After careful review of the original video I found that there are ONLY two objects in the picture.
#1 The motor.
#2 The hand.
So without a good, reliable, reference such as a ruler or another object of known size such as a coin, I made the assumption the hand is just an "average" male hand.
And, also, just based on my own experience of over 40 years of working with hardware and parts and wood in my own hands, I got a pretty good impression of the scale of this thing just from watching the video a few times.

SO, I took a stab at it and made a size assumption on a couple of the parts.
The rest fell into place from there.

I also assumed this device was mostly made of off-the-shelf materials so I just went to the hardware store and found stuff that fits and ordered common magnets and ferrites. (Still waiting for ferrites) It does appear the ferrites used in the original video were special order, plated, ferrites of unknown formula.

Parts list that I have so far:

(1) 7" diameter, .250" thick acrylic disk.
(6) 1" stick on feet.
(2) .500" X .250" X .250" neodymium "switch" magnets.
(1) 2" X .250" X .250" neodymium "stator" magnet.
(1) .625" X .625" X 8" hardwood support.
(1) .625" X .625" X 7" hardwood support.
(1) .3125 wood dowel cut and fastened to make "L" shape.
(1) Return spring from Pilot G-2 pen.
(3) .250" ID X .625" OD ball bearings.
(1) .250" stainless steel all thread shaft. (Cut to fit)
(4) .250" stainless nuts.
(2) .250 stainless washers.
(3) wood screws.
(1) 4" diameter X 2" wide aluminum drum / rotor. (air intake pipe for diesel engine)
(1) .250" thick X 4" diameter wood disk. (rotor hub)

This is just a quick mock-up that I threw together this afternoon.

My upright supports are a little to tall, still need to fabricate a rocker for the lower magnet, many things will need to be squared up and adjusted, I am still waiting for parts, and my finished product may actually be all acrylic.

That is all for now.

This is true but; when that is the ONLY reference object next to the motor, in the video, what else are you going to use?

Actually, yes, his Texas phone number is on his http://www.callowayengines.com/ web site.
But its my understanding he sold the design, therefore a contract exists, which likely contains a non-disclosure agreement and I do respect this and will not bother him.

Thats pretty cool.
My own formal training is Airframe & Powerplant, in 1981, at Colorado Aero tech.
I am fully trained qualified to work on the real thing.

Actually it is grate pleasure  to know and find colleagues here.
Thanks for your remarks, and motor owner tel. If it is still on, I will try to call him personally and ask some questions, hope he will answer to call.
Well, You have better design scale, guess it will be faster in RPM
Thanks for detailed explanation of your design. I really appreciate it! Very good job!

How you are going to get power from motor? high voltage static energy to capacitors or simple impulse coils with capacitors to discharge them to batts?Are you able to share that or I am asking too much Sir?

[Scorch]

I do believe Robert's rotor is a slightly larger diameter than my 4" rotor.
His is probably somewhere between 4.250" to 4.750" diameter maybe even 5.00".
But I have lots of stuff laying around that is right at 4.00" including clear, acrylic, tube so that's what I am going with. 

Don't know about RPM.
This is probably dictated by the strength of the attracting (stator) magnet.
Some say a PM motor should have a run-away RPM.
I believe this toy is limited by air friction and other losses and RPM can also be controlled by timing of the mechanical switching in a more efficient device.

I do not expect to do much work with this demonstration toy; IF I can get it to run at all.
