Gene,
K7NV has a web site and builds PP motors for the owners or for resale, his
site has a lot of info on how to take these PP motors apart, rebuild them
or lube them for service. Hope this helps-

What is the maximum DC voltage used successfully/recommended for one of
the "small" PPM's ? What speed was accomplished and how was the brush life
at that voltage ?
I 'm building a power supply to put at the base of the tower and can
change the voltage from about 30 to 48 volts in 6 volt steps. Cable to PPM
will
be 100 feet of 3-#12's. I'm figuring about 0.5 ohms and about a ten amp
demand i.e. a 5 volt drop.
Any suggestions will be greatly appreciated.
Thanks,
Gene / W2LU
