First off, I want to note that I think cooling the can of the motor is a good idea.

Does this not somewhat contradict the discussion about motor fans that blow on and cool the can of the motor while it is in use?
In that discussion it was stated that cooling the can doesn't really give much benefit, but cooling the COMM is much more important.

This device only cools the can, which cools the magnets. This will make them more powerfull, at least their power will stay a bit longer untill the motor reaches a high working temp. But this does not really do anything to cool the comm, and even if it did, which it would only by convection since there is no real contact between the armature and the can other than a very small ammount of surface contact between the bushing/bearing and the shaft, it would warm right up on the first few seconds of use.

What this lends me to ask is: is using a fan that blows on the motor can still a good idea since it will help keep the can cooler?? I think so, but some think it isn't much help.

The reason people say not to put a fan on the can of the motor is because it works against the natural airflow of the motor. Since a motor sucks air in through the endbell and blows out the can vents, it seems to be more beneficial to help the motor along with the process and force air into the endbell. Sort of like supercharging a gas engine.

For the beer cooler option.... There is already some comercial units available to do this job, It will certainly not be as cold as with the one "nordheim" as made.... ... But if it's what you really want I will save you some money
Beer Cooler / Coffee Warmer

Just a note! When you use the Freezer your armature and comm will be cold also, it does not only cold the can, you can read the armature temp by spotting your temp gun true the side hole in the can. The temp will lower faster on the can but the arm will follow.

They're easy to make. Just have to use a larger copper pipe split in half and 3 peltiers instead of 2

So why not just flip the fan over to force in instead? Only takes a screw or two?

I like to give credit where credit is due. Ronald has come up with a great cooler. I received mine last week, and boy does it ever work well! Much better than I thought it would. Usually smaller fans tend to be loud, so I was expecting this to be pretty loud, but it really isn't bad. Keep up the good work CrazyRonny.
