However there is more testing to do. Learn as much as you can from Bedini circuits. I believe that he has great understanding in this area, and I respect him greatly.

Thanks Jason for the tips and once again, no rush on the tut. When your bored and got a minute spare. Cheers.

So the diode is unnecessary you say? Even restricts the flow somewhat? I was reading somewhere that it helps protect current from flowing the wrong way thats why I put it in there. I'll remove it from my setup and see if it makes any difference. thanks champ.

Okay, I have reread this Bedini article: http://www.rexresearch.com/bedini/bedini.htm
and I am uploading a circuit diagram. It appears that Bedini constructed his coils with one layer of wire wrapped on top of the other; the bottom layer for pulsing thr magnet on the rotor and the top layer for capturing the BEMF. Am I reading this correctly?

Has anyone here who is building pulse motors used air core motor coils? I have a pulse motor which uses iron core coils but has extreme heating problems. I am positive the heating is all due to eddy currents within the iron. My rotor is made of ferrite permanent magnets. I am running it off rectified mains voltage fed into a capacitor, which stays at about 160 volts. The motor when in operation uses about 800 ma.  When I power up my motor it rapidly accelerates to 4000 rpm but after only a 2 minute run the cores are heated to about 175 degrees. Probably the main factor which causes heating in my cores is that I use pulse width modulation to control the motor speed since this is the best way to control motor speeds at higher power levels. Therefore the core is turning on and off multiple times as the magnet passes the core. The next thing I am planning on trying is winding some flat air core coils to drive the motor unless I am told something about air core coils that I had not considered. I realize that air core coils are not going to produce the same amount of flux as a iron core coil which means I will have to drive them with higher power pulses, but I dont have any other ideas about how to deal with this heating issue.

I suggest you upload a circuit diagram or photo. Then take the time to go back and read this thread from where Jason came on. That way, you will be up to speed and some of your questions will be answered.
