I recently purchased a new wrapping lathe to replace the one I had built a number of years ago. I was suprised to find the new Lathe which comes with the standard "sewing machine" type motor does not have a reverse. I know just enough about AC motors to be dangerous and I suspect there is a way of wiring a reverse switch into the motor (it is not as simple as reversing polarity). Has anybody ever tried it?

Thanks

Jim

I wanted to do the same on my Renzetti a while back and they told me it could not be done. I prefered wrapping with the butt to my left, now I wrap with the butt to the right.

That is a shame.

Motors I've reversed actually had wiring diagrams showing how. Other thoughts.....
A quick look around @#$%& and I see sewing machine motors both clockwise and counter clockwise.
Do you have enough room to reverse the motor end over end in its mount?

What's a shame??

Depending on the wrapper you got and how the drive is set up you can put a twist in the drive belt if it's like a big "O" ring and that will reverse the chuck rotation. It will wear the belt though if you don't have the right set up. The Custom Power Wrapper has a reversing kit that may work for you.

Great thought Jim. Misalign the pulleys a bit and the belt/ring shouldn't eat into itself.

The polarity is usually changed at the field via a reversing switch. Some of these motors (Universal/Brush type motors) used to get reversed by mounting the brushes to a mechanical "switch" that turned them 180 to the field. That set up used a common two wire on/off switch. The more modern method is switching the polarity electronically to the field. The "old school" way is still used on some 110V Drills & Impact wrenches, where you rotate the butt cap 180 degrees to switch motor direction.

If you're just looking to run the wrapper a different direction to wrap from the other side, Jim's "figure eight" suggestion with a belt would be the easiest way out. You may have to step up the o-ring one size to do it. If you're looking to switch back and forth between forward and reverse at the flick of a switch, I'd take it to the local electric motor shop (like a rewinder) and have them wire a reversing switch in.

I hope some of the wrapping machine companies read this. I often wish I could reverse my machine. Like when I'm doing a long underwrap while watching a ball game out of the corner of my eye and realizing I just "back-wrapped" 20-30 turns. lol

This is one of the many reasons I always push the Flexcoat DL747 . It free wheels so easy you dont need a switch to back it up and you dont have to worry about twisting belts . Just my two cents worth

Jim, If you would do a search on Renzetti Motors or do a search on my name Terry Morrell ( all dates ) I posted a question on July 30 2004 almost the same. Can't remember the name of the guy that answered it but the post was answered.
