There are so many variations of ring rotators that it is not completely safe
to answer this question however I have a number of rings with a motors
similar to your description that I purchased in the 90's. There is no motor
stop or limitation on mine. The only limitation is the 500 ohm potentiometer
and I am not sure how much range it is using during a normal 360 degree
rotation. Also I believe that the 24v German wiper motor is still
manufactured and that Carl quit using it due to its cost (if I recall >$200)

I have an older model ring ... the motor is a substantial (hefty) 'box' with
a
wire guard over the output gears ... my question is this: is there
Overtravel
built in? There's mention of OT in some of their instructions but no real
details, so I don't know if it is a real OT (failsafe) or just soft limits
with
the end stops of the controller and thus not really protected against wrong
wiring or run-aways. Does it have a relay/diode inside to prevent continued
voltage of one polarity from being applied yet still enabling the other
direction? I want to be sure of this before I mess with running the motor.
Since these are so old and since I've heard the motor itself hasn't been
available for some time (wiper motor) I don't want to risk damage.
I've written Carl a little earlier - I was hoping to get an answer before
the
start of the weekend in the morning so I can make progress on finishing this
aspect up, thus the additional post here.
regards,
Gary
