Self-Runner Spikes
Hi
I finally got some time to experiment with the self-runner coils. As I experimented thoroughly I conclude that the high voltage
spikes appear after the swicth opens like the collapsing magnetic fields when pulsing the coils, but this time the coil is charged by the moving magnet instead of the battery. When the battery is pulsed, the spike is release afterwards, when the relay opens. So I think that as we pulse the battery these spikes get stored in the capacitance of the coils and build up there for better pulsing each time, but not so sure. Maybe we can capture these spikes and charge another battery with them. The attached scope shot clearly shows the fact that the spike is released when the relay is opened.
