Permanent magnet assisted motor coil designs

TESTING THE ELECTROMAGNET YOU DO NOT NEED AN
OSCILLOSCOPE. BUT A CHEAP ELECTRONIC SCALE.
PLUS THE STUFF THAT MONKEYS DO NOT HAVE IMAGINATION.

Yup, I've got a couple different scales. That's how I figured that for my setup 11 degrees before TDC is the distance for the most strongest pull on the rotor in attraction mode. I've been doing all kind of pull tests as I go.

Does anyone have any tips on making these rotors more true? What I mean, is that every rotor I seem to make, no matter how careful I am, there is always a certain degree of wobble. I have my bearings as perfect as possible, and my flywheel is turning true, but my 2 new rotors I cut have a wobble? Its close enough to be just fine for what I am testing, but without having a machine shop, what are you guys doing? I have made a jig saw jig to cut circles out of wood. Worked well, but had a bit of wobble. I used a hole saw for the next set with wood again. Still have a slight wobble. Using a drill press did not make a difference. This time I ordered pvc board and cut my rotors out using a hole saw. They have a little wobble. When I glued stuff to a grinding disc, it ran perfectly true. But a little pressure and that stuff rips off easily because the grinding disc just sort of separates. I will be fine with this build, and I will probably just order some rotors machined if I plan on a final design next so I can get the magnet gaps minimal. But it's just frustrating with normal tools, I just cant seem to get it right. I see many out there made using lexan or whatever clear material so you can see through it all, but that is a pretty expensive material to work with just to get done and still end up with rotors that are not true again. I am about to try and modify a circular saw blade. Having the metal backing is not bad for this particular motor design, but I wanted the ability to switch thing up more as well as sandwiching another layer of coils so I can use both sides of the center rotor magnets. Any tips?

CAPTAIN GET OUT OF THIS MOVING MAGNET WAY OF THINKING THINK OF NO MOVING PARTS
TECHNOLOGIES. THE HIGHER THE FREQUENCIES THE MOST ENERGY. REM KILOWATT HOURS.
THINK MICROWAVE AND HIGHER ENERGY GENERATOR.

WHICH ONE CARRIES THE MOST ENERGY?

At a glance without seeing them closely on the grid. I would say they are all the same? Just different settings views on the scope?
