== Project Discussion Transcript (the conversation that started it all 08/05/2010) ==<br />
<br />
'''Bradley:''' how much experience do you have with linear motors?<br />
<br />
'''Daniel:''' do you mean motors that produce linear motion or actual linear motors?<br />
<br />
'''Bradley:''' linear motors<br />
<br />
'''Daniel:''' I have read about them<br />
<br />
:D<br />
<br />
that's like the maglev principle, right?<br />
<br />
'''Bradley:''' kinda, the maglev works with the idea<br />
<br />
the linear motor is the propulsion<br />
<br />
same prinicpal as a rotary motor<br />
<br />
but applied in a straight line<br />
<br />
I plan to use it in a car hubless maglev design<br />
<br />
as in the vehicle has no contact with the wheels and is held up my magnetic force<br />
<br />
'''Daniel:''' that sounds fascinating<br />
<br />
'''Bradley:''' doesn't it<br />
<br />
'''Daniel:''' yes, it does<br />
<br />
I would be willing to help<br />
<br />
that sounds like a blast<br />
<br />
'''Bradley:''' I hoped you say that<br />
<br />
I want to build some prototypes and see how well it works<br />
<br />
'''Daniel:''' yeah, nice<br />
<br />
'''Bradley:''' then throw it on to bike based power wheels<br />
<br />
'''Daniel:''' you'll have to explain the physical principles sometime in person<br />
<br />
'''Bradley:''' think mag lev train<br />
<br />
'''Daniel:''' yeah, except with wheels<br />
<br />
that don't touch<br />
<br />
'''Bradley:''' the wheels take the place of the track<br />
<br />
it's a vertically circular track if you will<br />
<br />
'''Daniel:''' haha, I just need to see some flux lines, that's all<br />
<br />
ok, so the rotation mechanism is similar to that of a stepper motor?<br />
<br />
so is the inside of the wheel lined with opposing magnetic fields?<br />
<br />
'''Bradley:''' yeah<br />
<br />
'''Daniel:''' I wonder how that will hold up under load<br />
<br />
'''Bradley:''' magnetic force is more powerful then gravity<br />
<br />
but yeah I want to see that too<br />
<br />
like can it handle 300 lbs<br />
<br />
I think neodymium magnets can easily handle that<br />
<br />
'''Daniel:''' the car + a rider?<br />
<br />
'''Bradley:''' yeah<br />
<br />
'''Daniel:''' conceivably this should be more efficient than a standard motor<br />
<br />
'''Bradley:''' yeah no friction<br />
<br />
'''Daniel:''' like a brushless motor<br />
<br />
'''Bradley:''' exactly<br />
<br />
'''Daniel:''' You know what, we may need to include some sort of rolling element to hold everything in place<br />
<br />
'''Bradley:''' rolling element?<br />
<br />
'''Daniel:''' well, ideally the outer rim would never touch the inner rim<br />
<br />
'''Bradley:''' yeah<br />
<br />
'''Daniel:''' and would "levitate" on the magnetic fields<br />
<br />
'''Bradley:''' yes<br />
<br />
'''Daniel:''' I guess we'll find out as we prototype, but I was reading that tolerances have to be really tight<br />
<br />
so if we needed to we could use Mag fields for propulsion and a bearing for suspension<br />
<br />
Also: http://www.sparkfun.com/commerce/product_info.php?products_id=8643<br />
<br />
'''Bradley:''' yeah there are companies that sell magnets in quantities of 100-500<br />
<br />
I think we would be looking at those<br />
<br />
'''Daniel:''' true<br />
<br />
'''Bradley:''' and a little flatter<br />
<br />
'''Daniel:''' so true<br />
<br />
'''Bradley:''' but I'm going to look into engineering texts on maglev trains and such<br />
<br />
I'm guessing they are using eletro magnets<br />
<br />
or even super conductors<br />
<br />
also there are low speed designs and high speed designs of linear motors<br />
<br />
'''Daniel:''' well, the control magnets have to be electro-magnets (obviously)<br />
<br />
'''Bradley:''' yeah<br />
<br />
'''Daniel:''' I know that maglev trains' active component is a liquid nitrogen/helium cooled superconducting magnet on the track<br />
<br />
'''Bradley:''' hmmm<br />
<br />
LN2 on a power wheels<br />
<br />
'''Daniel:''' the level of coordination required for a bullet train's magnet systems is scary<br />
<br />
haha, it depends on the superconductor, now you may be able to do it with liquid helium<br />
<br />
they are getting closer and closer to room temperature<br />
<br />
but they aren't there yet<br />
<br />
I studied this in Materials Science<br />
<br />
'''Bradley:''' closest I got was physics 2 and parts of quantum mechanics<br />
<br />
'''Daniel:''' close enough<br />
<br />
anyway, I don't know if we can sustain electromagnets on low power<br />
<br />
for the levitation part<br />
<br />
'''Bradley:''' oh and lots of empirical science in highschool engineering<br />
<br />
I need to study magnetism again<br />
<br />
do they require high voltage?<br />
<br />
'''Daniel:''' not necessarily<br />
<br />
'''Bradley:''' lots of current?<br />
<br />
'''Daniel:''' the magnetic field is proportional to the current<br />
<br />
I just had a thought about the positioning of the levitation magnets<br />
<br />
for some reason, I am thinking we'll need an odd number of magnets on the outer rim and an even on the inner rim<br />
<br />
so there's not really a low equilibrium position<br />
<br />
are you going to be at the space tonight?<br />
<br />
'''Bradley:''' nope<br />
<br />
I'm going to chicago<br />
<br />
I'll be back in the space next week<br />
<br />
'''Daniel:''' ok, I am going out of town Friday-Sunday<br />
<br />
we'll coordinate<br />
<br />
'''Bradley:''' ok<br />
<br />
'''Daniel:''' I don't know if you read this article, it looks very good: http://www.recumbentjournal.com/news/gear/item/53-hubless-wheels-emerge-on-recumbent-<br />
trike.html<br />
<br />
Oooh! We can implement a sort of regenerative braking (maybe)<br />
<br />
do we have a wiki-space for this project?<br />
<br />
'''Bradley:''' not yet<br />
<br />
go ahead and make one<br />
<br />
'''Daniel:''' will do<br />
<br />
'''Bradley:''' though I am curious as to what kind of magnets they used.<br />
<br />
I'm assuming they used those cheap magnet strips<br />
<br />
'''Daniel:''' the article says it uses magnetic strips<br />
<br />
but it doesn't state what kind or what strength<br />
<br />
'''Bradley:''' yeah, that makes my mind think craft store supply magnets that come in rolls<br />
<br />
I'm assuming the bulk of their cost came from the fact they used high grade aluminum<br />
<br />
and the machining on those hubs looks professionally done on a lathe<br />
<br />
or a water jet cutter<br />
<br />
I'm thinking the heavy duty ones will work<br />
<br />
'''Daniel:''' I wonder if we could embed square magnets into the frame of the wheel with good results<br />
<br />
it seems to me that most magnetic strips are rather weak<br />
<br />
'''Bradley:''' I was thinking of gluing them for a working protype<br />
<br />
'''Daniel:''' right<br />
<br />
'''Bradley:''' and using kids bike wheels<br />
<br />
we can remove the spokes and hub once we are satisfied that it will work<br />
<br />
'''Daniel:''' I am going to copy and paste this conversation into the wiki for future reference</div>Dantheman2865https://www.i3detroit.org/wi/index.php?title=Hubless_Motor&diff=890Hubless Motor2010-08-05T21:04:56Z<p>Dantheman2865: /* Project Discussion Transcript (the conversation that started it all 08/05/2010) */</p>
