   I've never encountered that voltage.  Direct current motors are   
   also mostly being phased out (pun intended) by asynchronous motors   
   with frequency inverters.

   That makes little sense.  If you're going to distribute power,   
   distribute it as AC so you save one transformer.

   Transistors?
