GK , Its to do with the oscillation I think, look up Q and inductance:-

"Q" is a most important property of both capacitors and inductors although it is actually dimensionless. The "Q" of capacitors is generally so high as to be ignored however it is the "Q" of inductors we mainly concern ourselves with. All inductors exhibit some extra resistance to ac or rf, "Q" is the reactance of the inductor divided by this ac or rf resistance.

@ comster,
I think I need a biphase motor control circuit.
I included my schematic.

ok let me correct that:-  The higher the value for "Q," the "purer" the inductor is. Because it's so easy to add additional resistance if needed, a high-Q inductor is better than a low-Q inductor for design purposes. An ideal inductor would have a Q of infinity, with zero effective resistance.

GEES!
Q in this case is fire,sparks and smoke.

DO NOT SAY THAT YOU WERE NOT WARNED!!

Lindsay is that you = Anybody?

Good to hear from you, and again thanks for all you have done, I can't speak for everyone here, but I'm honored.

@comster, sorry I didn't write back to you, I had to rush to get out of the house...had urgently to go somewhere.

So q doesnt mean what i thought it did, Apologies
