Well, I was kind of thinking of a non-cylinder halbach array, I did this quick inventor render. (note: Ironically enough, I think I put the arrays in the wrong direction...) So the springs would keep the magnets at repel-floating distance constantly, and when force is applied on the upper...

Alright thanks for the clarification. I'm really just throwing the idea around to get some feedback, so everything is appreciated :p

Thanks for the reply, but that thread doesn't really concern the subject of halbach arrays, unless I missed something :S

Oh and I forgot; Is it possible to set up a halbach array with non-cubical magnets?

So I'm thinking of this shock absorber involving magnets, but to reduce the weight as much as possible, I thought about using a halbach array of magnets to be able to repel as strongly as possible with the least amount of weight. The only problem is that I haven't got a clue as of how to...

Just another "request"; is there anyone who knows where one could find wheelmotors for purchasing? If anyone had a link or something that sells just something along the lines of this, I would be thrilled.

Ah, I see. Right now this is just a hobby project. I just think it would be ridiculously fun to ride a pair. imcjoek, could you clarify what sets apart a sensored and sensorless motor? And thanks for your concern, what is it exactly that makes these batteries unsafe? And since the application...

Does anyone have any ideas as of which type of motors would be best to use? As far as I've gathered there's brushed, brushless and AC / DC motors. What I haven't really gathered was the advantages / disadvantages of them all. And perhaps slightly off-topic or in the wrong forum-section (I'm not...

Thanks for the interest and the quick answers! Regarding the last reply Bob, which drive mechanisms are you referring to? The image I was having in my head would have more of a closed-type frame to hold the battery parts, and possibly some sort of system communicating and calculating the speed...

Another question; Reading around a bit about ultracapacitors, would it be possible to use an ultracapacitor instead of a battery? I'm not sure if it's needed in such a small application, but it seems as if the higher power output/input would be needed for quick acceleration, and to be able to...

Hello there! I'm really only proficient when it comes to software, but this idea (slightly influenced by various sources) sprung to mind, and it would involve the use of small electrical motors. So my experience with electric motors only stretches to a fairly unsubstantial physics education...
