@Jeanna and All

Bifilar is 2 pieces of wire wound on the same coil form be it toroid, straight or air core.

Trifilar is 3 pieces of wire wound on the same coil form be it toroid, straight or air core.

Each wire can be a different awg and/or a different length or all the same.

This is the standard definition.

I think the people on JT has a different definition which is confusing to new people reading this thread.

Hope this helps,

I believe most folks here know that bi=2 and tri=3.

One can make a Bedini motor with a trifilar coil if they want, many have done it but, I didn't see the need for it.

@ Jeanna:

If I can find the link quick, I will post it here.  This guy gives a great and simple explanation of the Bedini system.  It is really very simple.  The coil, unlike the way we are using them here, is actually 2 different coils in one.  One acts like an electromagnet to make the motor turn and the other is a trigger coil that uses the back emf for charging and, also turns the transistor on and off at the correct time.  This is why my motor can turn at such high rpm's and Jonnydavro's single magnet motor can turn over 18,000 rpm's using the same circuit. All of my motors charge more on the battery than they take to run.  It is incredible.  I think Gadget has one that is still running after 6 months.

Actually, right now on  my single magnet, no bearing Bedini, I am not even using a core at all.  Just Lidmotor's transformer coil and the rest of the Bedini circuit.

The above link is to part one but, check out his other vids as he has some great schematics and animations describing what is happening way better than I ever could.

I have a feeling the rs wire are the same weight ....

Same materiel same mass same resonant freq ....

MK1:

So, you are saying that you have a wire diameter of X and another of Y and they are two different lengths but, there is enough of the longer thinner wire to equal the shorter thicker wire in mass?  If this is what you are saying then, I probably have to agree with you.  Knowing RS and their suppliers (China) it is probably done by weight/mass.  Very good point.

@pirate

You got it !

Now if you ask me why this is important , i believe it is the best way to transfer the full amount of power between the coils.
