I've used these motors and they work excellently.  I've found that the
ones that have a two stage compressor have longer shafts which
simplifies the rotor mounting.  Generally async gaps do not work well
with OBIT's (nor with NST's), the xfrmers tend to be destroyed.  However
a sync rotary works well with those xfrmers, but vacuum cleaner motors
cannot be easily made to run in sync mode.
