plastic motor can?

plastic motor can?
any companies ever try a plastic or composite can instead of the heavy metal?
or would it take away from the magnets?
I'm sure it would save quite a bit in weight....
just curious....

Indeed the magnetic field would not stay contained....

thanks.... had a feeling that was the reason.
I'm just surprised that there aren't more new innovations when it comes to motors...
but I guess if it isnt broke, dont fix it.

Has to do with the rule-book which is used in all sanctioned racing.
Why produce something for a small market wich isn't allowed to be used???
That's it.

Due to the fact that the rules are so rigid and being in place for such a long time, motor developement has reached its peak. Any "innovation" you see now is just for marketing purposses.

huh... running more than 20 runs without rebuilding a mod, and neither loosingperformance (tested and tried), how's that sound? Marketing? This is called the Orion/Peak V2/Revolution/Vantage/However they call it,That motor with angled brush, you know...
Seriously... great stuff for weekend racers like me how don't want to rebuild every run!

would they have allowed some of the legal motors out now, say 5, or 10 yrs ago?
and if the market was so little outside of racing, then only motors that were legal would be selling.....

Also a plastic can would melt

Not sure what happened to the post I made....must not of made it.
In a nutshell, most cars are underweight anyways, so no need to save weight really. The termal properties on the best plastics(which are very pricey) aren't much better than the worst metals. The can does aid in the cooling believe it or not.
There are plenty of plastics however, even cheap ones that would stand up to the heat......most endbells are plastic.
Not sure where people are getting no new innovations....4 magnet systems, the new orion v2 endbell, etc.....all keeping pushing the envelope. The biggest problem is that the rules really handcuff us in what we can design and still be able to sell to racers. If the motor isn't legal, you won't sell very many of them.
I have new stuff in the works with my company, including a motor that skeets all the rules.....probably won't sell a ton of them, but maybe get ROAR to open their eyes and give us some room to work with.
I just find it funny.....NEO magnets are 100% illegal for brushed motors...yet ROAR publishes Brushless motor guidelines and NEO mags are perfectly legal for use. Gotta love the fairness in that crap.

I have to agree with hardriven RC. Things like the 4 mag system and the V2 brushes aren't that unique. The rules really do cramp innovation. They may be unique to the rc industry, but things like this are common in the industrial motor market.
I don't know about a plastic can, but I know hacker used to make a carbon fiber canned, brushless motor for airplane racing, where a small amount of weight makes a huge difference.

another advanage of metal cans is that it acts as heat sink for magnets. heat is the number one enemy of magnets, the hotter a magnet gets the more it looses its magnetic properties.
