Im trying to have dc motor hold and rotate 4 wings with a total waigh of 3.5LB at very low speed 5rpm or 3.5rpm if can fine one.
Im basically building a indoor garden light mover but for LED, so the LED are going to be on the wings moving slow, preventing heat spots and sharing direct light everywhere.

So I wan this moto witch is moving my lights to go back and forward automatically continuously like every 2 full turns or something like that. The reason i wan it to go back and forward automatically continuously is for safety with the wires, I can make the wires long for them to move back and forward also.
I use light mover in the past witch they use Magnet mounted on each end of the reil, but sometimes they dont work when they go on and off with a timer, Im hoping for a better solution.

I was thinking maybe this http://www.frightprops.com/electric-motors/controllers/picovolt-0975.html
but this do a lot different stuff, so i wounder if is another simple way.

please help

It doesn't have to be that complicated. Just a piece of metal, maybe a foot long, to connect your light mover to one chain link that will go back & forth.

There is a few way of making the motor uni-directional, this avoids continuously reversing the motor, anything from a simple wheel and connecting rod to the dual rack/half gear wheel.
Wouldn't be much larger than any other reversing mechanism for this application.

do move back and forward from side to side. i wan it stable, like a sealing fan.

I can use this idea to move 2 fans at the same time, if i can have one rotor move the chain back and forward.

thanks

im sorry i dont get it.
to make it simple of what im doing, i need a sealing fan to spin slow, and then after two spin, spin back, and the back again... continuously non stop. only when the timer go off

12 sec./ rev. is quite slow. I would go with slip rings to feed power to LEDs, & use a gear reduced AC motor.
Your ref. motor controller should provide one stop shopping @ a lot of $.
