Perendev Magnet Motor - Does IT WORK?!

We take a look at the perendev motor and see if it really works.
You can buy the kit here:

Update - After some analysis I decided to make a shielded mu metal variant which (in theory) could isolate the magnetic fields. I think this is what the original version is based on. I plan on building this variant in the next couple of months.

I had an idea like this in 8th grade but I couldn't find a way to adequately shield the magnets so the only part pushing on the magnets in the wheel would be the part that repels them. You always end up with the magnets pushing both ways and only adding a small amount of thrust. So they always come to a stop after a few minutes.

You can get longer lasting spin with no magnets and a flywheel. Permanent magnetic cannot be used to make a motor by themselves, since a unipolar magnet cannot be created, electrical fields are typically used to create a mono-pole moment (even though an electromagnet is still a dipole.

Great job. And thanks for your honesty, not like the others YouTubers fooling people.

[lunarrn]

Have you tried removing every other magnet to see if the interference would be reduced or eliminated?

Ya, I fell into this hole too for a while. I bought a bunch of my own magnets and fiddled with them. I slowly learned that this will never work for a simple reason. A magnetic field isn't energy, it's a force. Seems silly, but it made things make sense in my mind. Energy is a transfer, a change in state. Magnetic fields are a constant force, unchanging. Even an electromagnet. Sure it can change, but not by itself. The current needs to change, which causes the change in the field. That's why, if you hold a magnet still near a wire, nothing will happen in the wire. It is exerting a force on the wire and it likely has an altered state due to the forces of the magnetic field, yet that state will be constant as long as the magnetic field stays constant.
A magnetic field is basically a handle. You move the magnet, it changes the state of the handle, which changes the state of whatever it's attached to. Don't move the magnet, nothing changes.
On these magnetic wheels, the opposing forces are constant, like you said. Energy, change, will always need to be added to the system to drive the wheel.
It's a really fun project to play with and a good way to learn about how magnets work.

Nice setup! I think, with some changes, this really could work, but I have to test it myself first.😉

Thank you for your honest video tutorials. I loved magnetism. Watching with full support from Canada 🇨🇦.

Drill a hole through those outside magnets and mount them so they can rotate! If done correctly you should be able to bipass the magnetic field of the next magnet in the series.

[kevincrossland]

So the main energy losses I can think of in the design are air resistance, bearing resistance and Eddy currents within the magnets, reducing these losses will let it spin for longer, although reducing these losses is also a challenge industries have dumped billions of dollars into optimizing

[sendeth]

You could also make the bearing that the wheel rests on to opposing magnets so that would reduce friction.

Cześć, Czy myślałeś o tym, żeby na przykład wyizolować magnetycznie pola interferujące? Druga opcja jaką rozważam to dwa lub trzy rotory. pozdrawiam Cię serdecznie, mam nadzieję, że nie będziemy musieli stworzyć magnesów jednobiegunowych.

My dad made a small one of these, totally different magnet placements, and the ones on the outside rings were on springs inside their sockets. he had smaller magnets between the larger ones on the inside disk that pushed opposite way and they were all spaced further apart. his, he put on the shaft of a dvd burner motor and connected it to a battery charger for AAA's and C's and then to a lamp. he got it to power the lamp while charging the batteries after cranking it by hand for a few to get it going.

How about if you make each magnet in their respective hole rotate freely. You may also need to change the placement of each magnet to minimize the tugging or stalling effects of the current configurations. In other words, in the new configuration, at any time or location, each magnet is either pushed or pulled in the same direction. There is no free energy that can be extracted from this type system. However, it can do some simple work within the limitations of the magnetic energy stored in the magnets. You may also add some coils in the feedback path to compensate the rotor slip caused by applied load.

[j.s.boehme]

All of the "functioning" Perendev motors that I have seen functioning have three sets of rotor/stators that are slightly offset so that one is in neutral while one is pushing and one is pulling..The angles of the magnets are supposed to allow more push than pull, creating continuous rotation. I'd love to see you do an experiment with this. Thanks and good luck.

[bungalowfeuhler]

I think that a concept along these lines has potential for generating a small amount of power with minimal maintenance by the user. But it’s maddening how every video of one in action always features a cut just before the rotation gets going and it’s suddenly spinning at high speed and there’s a subtle whine that sounds suspiciously like an attached motor.

[shubbz]

Love your dedication, if you can make energy next to nothing it is a good start and magnets could help as a lubricant and be one component of a bunch. I'm new, don't critique to hard.

[cewotu]

Great and honest - as opposed to so many others cheating... Thanks!

[hotrod]

Can you use two wheels geared together for a continuous magnetic repelling effect?

[jamesbodiford]

I have a thought have you tried using a cam on your shaft with a leaver that pushes a are out from the spinning magnets. Or a leaver that would push up a small piece of lead plate in between the magnets to block the magnetic filds
