Hi Vortex1,

thanks for posting your comments.  I agree with you in the finer finishing of the cut laminations. I do that also and mostly with parts I want to marry together. I place a fine sand paper on a flat surface and use a perfect 90 degree block to keep the end of what I'm sanding leveled.

As for the large motor. I don't think it matters it the motor rotor has spiral sections or strait. I chose this one because the small one I was experimenting with I accidentally dropped the rotor (just after I finished cleaning it) and the commutator hit another sharp metal piece and cut the copper wires and is unrepairable. Previously I had it working once I got the timing of the brushes right. So I decided to get something more robust. If I do get it working it can only be better as there is less resistance in the winding and mostly because it's a 120vac compared to the 220vac motors.

Nice build, did you adjust the brush timing?

Thanks for sharing

Thanks Luc

No I have not played with brush timing, but I have played extensively with the FET circuit and variations of it as well as magnet placement, without much improvement. My motor does not lend it self well to brush positional changes. I won't bevel the brushes either as there is no definitive statements that this is the way to proceed. The fact that it is hinted at means it is probably not the way to go, as the suppressors would not allow truth to leak out from Brad...right? especially if he is that tightly gagged. So whatever Brad says to do, maybe it would be better to do the opposite....

I will await further messages or information before proceeding with major changes to this particular motor. Meanwhile I have lots of universal motors on hand to play with so may start another build with a motor that is expendable in that I have a few of the same type for comparison.

Cheers and good luck with this cryptic puzzle guessing game.

Dear Brad and all.

No PM's yet but possible forward progress??

Comments/observations most welcome.

Cheers Grum.

Hi Grum, Are your field coils stock or did you rewind them?
You were powering the little light with the field windings correct?
If so was it just one or both coils?
I have the identical motor as yours I believe , but the output from the field coils is small.
I also have another motor where I replaced the field coil stator with a PM can ,with added collector brushes.
I can draw off the brushes but I can't combine them or feed them back to the supply.
As JimBoot stated you can power the motor with various  brush locations.
I am still working on shorting, the lenz effect needs to assist I think.
Thanks artv

Sorry for the over size pic I hate that.
Not sure how to correct it, If somebody can please do.

Load your pic into paint then you can alter the size and save as a jpeg. It's all menu driven and simple
