Hi Has any one tried using rare earth magnets to improve the field on old open frame motors, or wound electromagnetic fields ?. I have a model where a can motor is hard to use. I also feel the original motor would be nice to preserve, because it adds to the caricature of the model. Thanks Stephen (cTr...Choose the Right)

I have done this to a couple of old Akane (HO) locos that belonged to a buddy.
The overheating went away and they were able to pull very well.. I used magnets
from these guys:
The ancient Pittman open frame motors (DC91? DC71?) exhibited a bit more
cogging but overall performance was much improved.
It was simply a matter of measuring the height of the old AlNiCO magnet and
replacing with (in this case) a couple cylindrical magnets of the same height,
side by side, straddling the screw that held the top and bottom plates of the
motor together.
Jim Thank you, been thinking of trying this for a while now, I'd like to try it on the motor pictured. Stephen (cTr...Choose the Right)
