Motors

The main movements of the telescope, azimuth, altitude and rotation, are controlled through (old-fashioned) motors and tachometers that use brushes. There are infrequent, but recurring problems with this because the brushes wear out. A web page was set-up, detailing all the known work done on the altitude, azimuth and rotator motor brushes and tachometers to keep track of what has been done, and hopefully be able to do preventive maintenance on the brushes in the future, avoiding any night time problems.
