Building one might be an interesting project, but don't be too hard on yourself if it doesn't work. Your workmanship will not be at fault, it is the physics that are flawed.
This is not a machine that creates energy by demagnetizing magnets. But if it were, then the amount of energy the motor could produce would be proportional to the amount to which the magnet was demagnetized, and the total amount of energy the motor could release over its lifetime is bounded by the minimum amount of energy required to magnetize the magnets in the first place. If you're curious how much energy that is ... not much.
See this is what bugs me about the last answer.
I'm sure the person that asked those questions meant it as holding 50kg suspended in air, via a rope or something. People have done these tests for a while now, and I'm sure there is more to the story, cuz, let's face it, holding something suspended in air, via a rope or whatever, with nothing like a nail or a screw screwed to the ceiling, is doing work (the latter examples have the power of friction on their side, that's how they work, which is not the case with a pair of magnets). It's like you holding that same thing suspended in air for a year. You must put in work to do that, right?
I'm sure that even physicists are missing something here... either that, or no one knows how to explain things like this person asked in plain language.
I'm an egineer BTW, but permanent magnets were never really well layed out in uni. But then you stumble upon things like the Perendev motor and wonder why no physicist will try and tackle this issue, dispoving it in practice, instead of just dismissing it as a perpetu mobile.
What I'm definitely saying is that there is no free energy, that's ridiculous... or maybe in a form we still have't disovered, who knows. But, using trapped energy in a magnet... that could actually work. The concept might sound weird to a scientist, but we all know that most of the time, egineers are the ones that "break the rules" in conventional science and that most revolutionary discoveries are done by them, not suits with Phds. And Perendev was a legit engineer, a smart one as well. So this leads me to at least consider this idea as a sustainable scenario, thus leading me to try and make one of my own.
Teach yourself the fundamentals of physics whatever manner works best for you. But until you've built a working Perendev motor and had the design and device peer-reviewed, please don't advertise it as a real alternative to solutions that don't break the laws of thermodynamics.
Hey, i could say the same about your link 🤷. Doesn't break the rules, but let's face it, it's not a viable alternative. I really can't imagine someone doing this in the age of electric cars.
