Up for auction is a set of 4, New,  HarbotFreight 12 volt drill motors, with chuck locking screws.

All Motors/ Transmissions are new, removed from new drills.  Drill model # 57366  or equivalent.  Manufacturer lists spec as:   12 Volts Dc,  550Rpm. 

These drill motors have been a staple of combat robotics for years.  I can't say if they are still up to the task of combat,  but I CAN say they are the best value for money if you want a low cost, rugged and powerful robot motor.
