bifilar wound wire or any wire that is  wound  closely  creates  what is known as corona  when current is flowing thru  it   corona  is a form of static  it will arc across the top of the wire just like the frankenstien movies

their is special wire coating  for this application to prevent the corona from burning up winding it is used in frequency driven motors

 this is why kevin west burns up so many stators

Thanks for sharing.  What coating is that?  I've been using teflon coated wire silver coated copper like Bob Boyce recommends.  I use the wire to wrap ferrite toroid coils bifilar.  I do have a curiousity towards electric motors and generators/alternators though.  With pulsing dc pwm the coils get hot but with a 60 hz inverter the coils stay cool.  I would like to explore higher frequencies though.

Regards,
Andy

As far as I know Kevin has not tried a bifiar wind in his stator.

The coating on my wire should stand for 2000 volts, so hopefully it will work. My diodes are rated for 1200 volts.

Once I test it I am going to get it varnished and baked.

Yes,

And thats why Tesla made aircoils with a spacing between his turns.

Should have this done in a few hours more work... I'm back at school now, so my time is more limited.

Thanks guys, i'll be working on it more soon, only a few more things to do before it's operational.
