   From the motor spec, your suspicions have to be correct as to motor type   
   and construction, and this motor could never directly produce DC.  It is   
   however possible to generate AC from an induction generator and rectify   
   it to DC.  This is probably not a good project for a beginner, but   
   searching on "single phase induction generator" would return some   
   interesting information.
