The temperature is up to 28F and I decided to give the rotor a try. It
works again!
So, I'm currently running the thing through a series of turns hoping it gets
any remaining water out of the motor.
It looks like I'm going to have to build a better cover to keep water out of
and off of the motor. I think in addition the investment in about 10 to 15
feet of armored, self limiting heat tape may be in the future. It will fit
nicely between the fins on the motor and with it running through about every
third gap it should not limit the cooling in Summer.
As the motor has to be mounted horizontally it is possible for a small
amount of water to collect between the rotor and field magnet poles. If it's
left to set there and the temperature drops I can see where it could freeze,
preventing the rotor from turning.
I see the new Pro Sis Tel models have what appears to be sealed motors. Now
I could go for one of those except for the price increase. They've also
changed the motor position so it should fit most towers without having to be
repositioned.
