So why now have Stern changed their flipper design, coils etc ?
It is reported that with the new SPIKE system they have returned to (conventional?) twin winding flipper coils which many (including Beaky & myself) have suggested they do for some time.
This means they would now have a PULL IN winding (fast, snapy, high current) then a HOLD winding (low current, holding power only) BOTH on the same coil former (3 lugs and wires running to the coil).
The way they HAVE done it up to now is electronically switching the coil on and off thousands of times a second to lower the power "seen" by the coil BUT the coil still gets hit thousands of times a second with the full voltage across a high power coil NOT a hold coil with many more windings and maybe this causes the overheating reported by many - I don't know for certain.
I have no idea if they have changed the mechanical bits but I would doubt it and they probably don't need to as I think the design mechanically is quite sound.
Ok.. so dual winding from now on....good move.
