Do commercial motors/generators produce eddies, why do builders build their own?

Do commercially available motors/generators produce electromagnetic-eddies/drag, why do builders build their own ?

I assume operating speeds for commercially available motors/generators  are used to avoid  electromagnetic-eddies/drag .

I have noticed that all the motors I have ever seen have either one less or 1 more  permanent-magnet  or  electro-magnet in the stator,  compared to the rotor,  I assume that is to eliminate a large amount of cogging-torque ( en.wikipedia.org/wiki/Cogging_torque ).
However,  if youre putting 2 or more generators on the same shaft I assume this design ( detailed above ) would make it difficult to UN-ALIGN the generators to achieve  "cogging-torque neutralization",   SO,   I assume thats one reason why builders may prefer to build their own generators,  so that they will have the same amount of permanent-magnets  or  electro-magnets in the stator as on the rotor,  so that they can easily UN-ALIGN them to achieve "cogging-torque neutralization".

'Builders building their own generators' seems to be a barrier to them achieving  looped/completely-self-powered devices,  maybe they should more often consider using the generators from wind-turbines, etc.

In fact, the cogging was never the problem it is an effect called Lenz Law relating to any induced current producing an opposing braking effect. The best way to understand it is by taking a strong neo magnet and dropping it down a copper pipe or moving the magnet along a thick copper or aluminum plate.

This is by far the best video I have ever seen which shows the effects we in the Free Energy community are trying to work around...https://www.youtube.com/watch?v=sENgdSF8ppA

Watch this video closely, study the effects, understand the how, what, where, when and why of it. If anyone can work around this singular problem then your the man and get a Nobel prize. It looks like magic doesn't it?, however that's the nature of science and it's always impossible until someone solves the problem then it's easy. I have done all the experiments in the video and you literally have to see it and feel it to believe it.

Again, solve this one problem and all the worlds energy needs are solved as well...

Eddy current losses are minimized by the use of laminated core steel. This is also done in other electric machinery where you find magnetic flux changing polarity or amplitude at frequency, like transformers. This also causes hysteresis losses in the core material which is addressed in the metallurgy of the electrical grade sheet steels. Together Eddy current and hysteresis losses are called core loss, sometimes referred to as magnetic drag. Cogging is typically not a significant factor in commercial power conversation machines at rated speed and can be addressed in design by using skews and or appropriate pole and tooth count. Servos and position control motors, or other speciality applications find methods to address cogging.

Everything you have said it true and known in the art in my opinion however by the same token everything you have said does not move the conversation forward to resolving the inherent problem. Therein lies the real problem in my opinion, most can describe a thousand reasons why something cannot work but not one in which it can. However when someone can find that reason we call it a "discovery" and everything changes.

Which begs the question, why dwell on what cannot work when we know it serves no real purpose?. I mean, I can agree with your reasons and fill twenty pages of similar reasons why we cannot work around Lenz Law however what purpose would it serve other than repetition?. There it is isn't it?, repetition, however favoring the status quo is not why we are here, we mean to move beyond the norm into uncharted territory.

So in effect you have described nothing I didn't already know 20 years ago but how would one describe something we do not know?. How do we move forward... that is the question in my opinion.

Onepower,
I was addressing the OP. I hadn't seen your reply until after I posted. I saw no mention of Lenz. At the end of his post he does mention looping which I chose not to comment about.

I think people should learn how things work before attempting to alter the technology and search for new discoveries. How do you recognize novelty if you are unaware of the present SOA?

WRT Lenz's Law, I consider it by definition of the minus sign in the ubiquitous Faraday Law equation. Actually, I'm thankful for it. Without the simple effect it describes, we would have only chaos.

I love to see people experiment with electric machinery and is a reason that I participate on these forums; to attempt to help them understand the technology, as in my reply to the OP. Do I think one of these experimenters will succeed in building a FE machine? Not really. But possibly something interesting will develop or I might learn something.
