Rotisserie Motor

[new smoke]

May be making my tank smoker into a rotisserie. I'm having a hard time finding info on what I need for a motor to run it. Anyone have any knowledge or experience with rotisseries? Or any advice on where to find the right motor?

Haven't done any rotisseries, but I've done a lot of looking into motors. Check out the Grainger catalog (online) there will certainly be a Dayton gear reduction motor to suit your needs. Once you find what you need, check Ebay. I've come across many low horsepower, low speed, 120V motors there.

My Dad has a ol spit setup using a electric mobile home auger...

Any idea what size of motor would be needed?

Depends on what you plan on rotating on a regular basis; a chicken, or a whole hog? Heres a few examples at each end of the spectrum:

Depending on whether you want to use A/C or more self contained D/C. If considering the later, you can look into RV slide out motors. These are gear motors that are ratio-ed to an applicable speed for a rotisserie.



I've seen them at RV surplus centers for around $75. Add a switch and deep cell battery to your unit and your good to go.

I know this place carries them. http://bontragers.com/

depending on what you plan on spinning with it, i would either opt for a Honda V-tec 4-banger or a 572 chevy big block... I wish. lol

another thing to think about too is your bearing/bushing setup(s). if it were me, i would opt for some brass or bronze bushings, then use stainless steel for the rotating rod. the dissimilar metals will act as a self-lubricating assembly and will work great for what you need.

as far as the motors go, i would also go with Grainger or MSC Industrial. either one would have what you need for the motors, as well as a gear box to match it. like others have said, i would size the gear box according to what you want to rotate with it. personally, i think that 139 RPM for the final drive ratio is a bit high, but that's just me. I would opt for something a little closer to 2-30 or so. think about it... especially in a smoker, that piece of meat is going to be in there for a while with indirect heat. does it really need to spin more than a few times per minute? hell... for a 1/15 HP motor at only 11.5:1 ratio, i wonder if it could even turn a whole hog safely. hell, at that speed, it'd probably start flinging drippings agains the inside of the cooker. lol

if it were me, i would opt for a 1/10 HP motor at 1750 RPM with a 80:1 or 90:1 ratio gear box. Then, for added fun, throw a speed controller (basically a dimmer switch for lights, but rated for motor use), and you can have even more control over the exact rate of rotation. by the time you are done, you are probably looking at around $200-$250, but that setup would probably outlast your pit.

I have a great heavy duty silage motor I plan on using for a rotisserie and was trying to find something comparable on ebay. Maybe some of these would work for you?

How many rpm's you lookin for? And how much you lookin to spend on it?

Ok, I've looked at some gear reduction motors and speed controls for $250-$300. I've also seen some pits online that look like they use a motor and and a large pulley to ratio it down.

I saw that one site said they turn their pit at 1 RPM. I should be able to use an electric motor and a large pulley to ratio it down and this should work like a gear reduction setup? Am I totally off on this? Just wonder if I can get a setup like this put together for less than the $250-$300? Thoughts on this theory?

Not sure how much weight or strain would be put on it, but you can get a great auger that feeds pellet stoves. 1 RPM and up to around 6 or so. They are on ebay all day long. "auger pellet stove"

I'm thinking that if the rotisserie is balanced right, then there shouldn't be to much weight on it. Right?

Is 100 in-lb of torque much?

You might want to give Lennox Hearth Products a look. They make auger motors for their pellet stoves. I've looked around at their site and can't figure out how to get a replacement. Here's a link to one of their units. The motor specs are in the upper right portion of the pdf. 1.28 rpm is pretty close to what you're looking for, I think. You might have to give them a call.

100 in # aint much. 12 inch pound equals 1 foot pound so a bit over 8 foot pounds. If you ever worked on a car, thats less than is required to tighten the bolts on a chevy oil pan.

What are you lookin at that has 100 inch pounds?

This one was on Amazon. Down in the technical specs.

The largest I saw for the Dayton gear motors was 250 in-lb.

Hmmmmmm. In all honesty, I don't know if that would suffice for turning a rotisserie or not I didn't see any specs on the ones listed on ebay. They are the same ones you posted here but no specs that I saw. How big a rotisserie you talkin about? How many pounds of meat at max?
