trigger delay
Hi Sephiroth,
Yes. It shortens the pulse width and delays the on time for the transistor.
Magnet N moves towards core and induces a reverse charge to base keeping it off. The moment that the magnet moves away from top dead center, the field flips and then there is positive at the base that turns on the transistor, which of course allows the power winding to charge from the battery.
Having the inductor I would imagine slows the time BOTH (just guessing at this point) for the reverse voltage to hit the trigger (keeping it off) and after magnet moves away from TDC it delays the positive that is necessary to turn the transistor on.
So for example in John Bedini's examples of the power turning on at 23 degrees (on 8 pole example I think), it might turn it on at 25 degrees for example. If it turns on later in the rotation that is the delay.
If it is delayed then that means the north field of the next approaching magnet will start to induce a field in the coil quicker than normal...in relation to when it was turned on to begin with...meaning that starting later and cutting off sooner will cause it to have a shorter pulse width...shorter pulse width is less current used.
