Here is a simple "Motor - Generator" that is using a Joule Thief type circuit and a single shaft mounted neo magnet. I show it running on a 2.3 volt 10 Farad super capacitor charged up to 1.25 volts. The amp draw is about 15 milliamps. "Maggie", the little induction coil, is also shown being power remotely while the pulse motor is running on the capacitor. NO---This is not a "self -runner". It is just fun to watch do it's thing. It will run a few minutes off the energy stored in the cap.
