[TowerTalk] Prop pitch rotor identity?

[John Brautlacht]

Hi listgoers.

I have an old antenna rotator that I'm told is a prop pitch motor. About the
size of a small car transmission. One large wire coming out every 90deg.
Where does one find technical information for these things, and who to talk
to about service or rebuilding? I'm used to the "packaged" stuff and have no
idea where to apply power to this thing. The nameplate is illegible and it
has 24V stamped on it in ink.

I've posted a couple pictures of it on the web if anyone's interested.

I'm looking at putting up a tower in the spring and summer months, so I'd at
least like to test it somehow.

Please advise?
