New permanent magnet motor on youtube from Roobert33

@CLaNZeR,

Beautiful work as usual. You're one of the few doing fruitful work here. I don't think people just offering ideas should be encouraged, even less opportunistic individuals clogging the bandwidth of the forum with trivial objections already understood to allow violation. The ideas of these constructions are trivial and what needs to be done is to apply very skillful engineering and craftsmanship. Those of us interested in this matter should study carefully the lessons given by the exceptional work done by the likes of @Roobert33. If someone doesn't have the means to do that he shouldn't rub it. Shouldn't even mention it. We all don't. Some of us are just more determined, as you are.

Having said the above I'd like to mention my concerns regarding your design. The experience I had with the first model adds to what was obvious from the get go -- the drum has to be very very light. This is every bit a watchmaking job. The interplay of forces to make it work is so delicate that any deviation would amount to a dead end.

Now I'm preparing my second variant with a substantially lighter rotor and an arrangement different from @Roobrt33's V-gate. It seems very promising if I can succeed in manufacturing the proper cam. Will try to get in touch tomorrow with someone who has a super precise metal erosion cnc. I was told that's the state of the art in the Swiss watch making industry. Unfortunately, I have only several days to do that and then, as I said, will have to replicate the whole effort in the states because I don't want to carry with me sharp pieces throught the airports.

The theory this is based is the expectation (one can qualitatively feel that by playing with the above device) that the mechanical work of lifting the stator is less than the work of the drum turning from standstill to the point of lifting. That last work isn't enough to overcome the sticky spot, as is known. That there can be conditions of the former two different types of work to be in favorable proportion has already been show in the case of the magnetic propulsory. the question is how we're going to implement it here. @Roobert33 has obviously done it, we should be able to do it too.

Roobert33 haven't done it - he admitted he was just joking with us. If anyone are able to replicate his device 100% correct (CNC "magnets", and a powersupply under his sweather), the device will not work - unless there is a powersupply under your shirt. Or have I missed your point?

A lighter drum, or bigger, heavier, more powerful magnets? I do not see the point in having a lighter drum, if the total weight of the magnets are relatively high anyways.

Are you suppose to be the person who determine whos ideas are good and bad? Offering ideas is the very reason most members actually are members of this forum. Ignoring ideas, bad or good, should be a shame. Who knows? Maybe the least obvious good idea could get us further. "I don't think people just offering ideas should be encouraged"; Those words are MEAN! How can you say that?

like I said all these ideas are trivial and posting more of these trivialities should be discouraged to keep the discussion focused. Non-trivial is the actual making of these devices and some individuals such as @Roobert33 are obviously better than others in that.

There's no need for a powersupply under a sweater. A small electric toy car in the drum will do it

There's no need for a small electric toy car in the drum either. Turning the drum by hand will be even simpler. No such things, though, let alone a power supply under a sweater. Instead we see a skillfully made device which needs careful replicating.
