Here is an interesting circuit which has application in both the generator above and non-Bemf motors. In this circuit an intermittent current input will maintain the polarity of the inductor over a large time frame. In one instance the DC motor is acting as a motor and the moment the source current is disconnected the DC motor will act as a generator maintaining the current flow. The DC motor is a low turn/resistance PM motor and the inductance is the 120v windings of a transformer cut down to form an inductor.
