@Skycollection,

Tienes razón! Buena suerte.

Yes and no.  How fast the external circuit switches current into the supercapacitor and the inductance of the supercapacitor will determine the peak voltage across it as a result of a switched current such as BEMF.  A little filter placed in front of the supercapacitor will protect it.

The other usual practice when dealing with capacitors that have high inductance is to shunt them with a high quality film or ceramic capacitor to absorb the spikes. I would also add an excess voltage shedding circuit in the form of a low voltage Zener and auxiliary load so that excess charging can be shed into the load. There are numerous ways to do this in addition to the simple Zener. Series/ parallel strings of LED that begin to light at the appropriate threshold voltage would work if light is the end product needed.

In the case of needing only light output it would be better to eliminate the super capacitor altogether and drive the high current BEMF pulses directly into the LED array.

@Skycollection,

Congratulations! It appears the LEDS just turned on by switch alone, without spinning the rotor magnet to trigger the oscillation. The the new addition of the oscillascope looks very impressive.

Maybe you can start a small factory to begin to manufacture those encased Pancake coils?
