I tried ordering the type of
motor found in a rotisserie
unit and instead of
getting ones that ran on 120 volts I somehow mistakenly asked for 12
volts AC. I burned the first 2 out by applying 120 volts without
knowing any better. They only turned for a few seconds and then smoked
and sizzled.
It took me about 20 minutes
to remember a transformer from an old cordless phone was still in the
barn and its output was in the low AC range. 9 volts AC to be exact, a
full 3 volts under what I needed.
The lower voltage makes the
motor go slower, which is a good thing. Now the time in between clangs
is closer to a minute as opposed to 30 seconds. I also adjusted the
location to intersect with the two main deer paths near our blueberries.
I've got a feeling this new
configuration will last longer due to its reduced speed and low voltage.
