   I suspect that you have a single phase AC induction motor- 4 or 6 poles   
   judging from the speeds. It will have a starting winding   
   You could tear it apart but ,as is, it is useless for a DC generator.   
   This motor wont have magnets- if you can see the rotor- it will likely   
   have conductors imbedded  and these are shorted at each end.
