Thanks, My mistake on wording, The Motors was my actual question. Just didn't think about it .
I do appreciate all the info from everyone & will definitely go all 12V.

A motor's rpm and hp is not determined by voltage. You can get, for example, a 1/4hp motor at 1,000rpm in 6v and 12v (arbitrary numbers of course) and they will both do the same amount of work. The only difference is beyond that is, the 12volt motor will consume half the amps that a 6 volt motor will to do the same amount of work. Then when you consider that these motors run for a few seconds a couple times a day, and the difference is pretty much a non-issue.

Now in a practical application and looking at the norm of what's commonly out there for sale, yes, a typical 12v motor you find will have more rpm and hp than the little rc car type 6v motors offered with most cheaper feeders out there today. That's not an apples to apples comparison though. There are 6v motors out there that match the performance of the common 12v motors being sold.


Here, for instance, these motors are very likely to have the same hp and rpm rating, they just have different internal windings and one uses 6v while the other uses 12volts. If the 6 volt motor pulls 5 amps the 12v would pull 2.5amps per Ohm's law. But both do the same amount of work.

Have been running the same, “On Time” feeders for twenty plus years. They have lifetime warranty, have had to replace one trigger “limit switch” on an analog feeder. Called them, explained what issue was, had a new switch in hand three days later. Only other thing I have done is convert a couple from analog to digital, personal preference as the digital units, well you can set your watch by them. They run on ten double A batteries, so 15 volts, and will run on one set of batteries for 12 months.
