Voltage drop is easy to calc. so only for short hookup ie 1ft

I found a chart, but it was for insulated wire.
It lists the current capacity for AWG 30, at 80 degrees C, as 2 amps. Does that sound reasonable for magnet wire? It also doesn't say if that is Max or Typ.
Not to doubt anyone on this but, how can these ampacity numbers be correct? Look in a 5HP single phase electric motor, they draw ~22A but only have 20 gauge magnet wire for the field windings. I tried about a year ago to find this information but couldn't. None of the wire companies or motor companies will show it.
Went to AAC where I asked my question and found this link - http://amasci.com/tesla/wire1.html
And here is the AAC thread - http://forum.allaboutcircuits.com/threads/coil-amp-rating-for-magnet-wire.71392/
Most useful source of information on the subject (including wire thickness) I have found is this: https://ludens.cl/Electron/trafos/trafos.html
