I am just curious how much of an advantage this might give, and how it may affect the performance & efficiancy of the motor.. Looks like a fun job and if it does give an advantage worth the work, then you have just taught us all how to do it  . Nice tutorial/how to. Not bad for a pimp without any monkies to help out  . |
Not sure if it will do much. Hopwfully it will hold the magnet together, as the one piece magnets tend to come apart. I am not sure if I should have wrapeed the rotor first, then applied the epoxy.

It would true it but I am not sure if my wrapping method is precise enough for that to perfectly balance it.

Easiest way to balance is to put it in extremely smooth bearings and spin it. Where it stops, lightly sand the bottom a bit. Spin it again and see what happens. Do that until the rotor doesn't stop in the same place every time and your done. There are more precise ways but nothing without a sophisticated machine that I am aware of.

I plan to use my prop balancer to balnce this rotor, and just sand it as you suggest. We will see how that works.
