Re: Smart Motors

Hi, Let me see if I understand this. You put some electronics that
has a hard enough time to get rid of waste heat on the back of a
motor that generates plenty of heat on its own. Then you include a
controller as well. All in one integrated package.

You fire up the whole mess and let it run. The motor gets hot. The
drive gets even hotter. Something throws in the towel and dies.

Now you are out of a (1) motor, (2) a drive and (3) a controller. But
hey, it was cool having all of them in one integrated package, wasn't
it?
