yep. Running a 12v motor.
I don't see anything fancy about the motors in feeders. Just everyday 12vdc motors.
Anyway,
With a standard 12vdc power supply (something cheap), you'll want to know what the motor amps are (really important), then select a power supply that has at least double the output amps as the motor requires, and hopefully a decent overload factor. Otherwise, you'll crowbar the power supply and the motor won't work worth a crap. (power supply will fall over and won't recover) Put a glass type automotive fuse (250vac/125vdc) rated for the output current of the power supply to the feeder on the positive side, just in case there is a short circuit, then you won't fry your power supply.
Radio Shack or a similar vendor should have something reasonable.
You can buy power supplies that are rated for motors, but you will have much less money for feed. You can also get 12vdc motor controllers, which can also be expensive.
Recently did a project with 24vdc motors at 5 amps. Used a 10 amp output power supply with a 150% overload for 114 bucks, and the world was still spinning properly. Could have spent 500.00+ on a different power supply, but not at all necessary. Very common practice in my world, and the motor people will also tell you this.
See, that wasn't so difficult.
Me, on the other hand, would swap all the motors out with PMAC's, and on the spinner plate would pre magnetize the motor for about 10 seconds, launch frequency set at 500Hz, and launch to full speed at 10ms. There would be feed flying! Probably would blow the feeder up tho
(just kidding of course, that would be really expensive!)
