If your DC motor turned at 1800 rpm then you want it to turn as a generator fairly close to that also, otherwise voltage and current drop off dramatically at the lower rpm's. The good thing is is that all permanent magnet DC motors instantly become DC generators when you go from driving something to driving it Yes just find a pulley arrangement that you can mount to the shaft and to your propulsion method so that the rpm’s of the motor turned generator are close to it’s design speed.
