How Much Torque For Lure Dryer Motor?

20 posts in this topic

Guys I want to be able to turn 50 musky baits at a time and smaller motors aren't cutting it.........

I am looking at two motors,

One is about $50, 6rpm and has 50 pounds of torque.

The second is $250 but has double the torque.

My guess is that fully loaded I may have 15 pounds of lures but another 5 or so for the shaft, clips, etc.

Two questions:

1. Will the motor handle slight imbalances better with more torque?

2. Would I be working a 50# of torque motor too hard if it's repeatedly turning 25 pounds?

thx.

@ riverman.....where are you getting the 6 rpm motor with 50 lbs of torque???????

Just remember, little bbq motors turn 15lb turkeys all the time. Balance is what's important.

If you use a low torque motor and load it up good or severely off balance, you will have more current draw. Drawing too much current makes the motor stall. Also, make sure it is rated for continuos duty and not intermittent. Is the torque rating in inch/lbs or foot/lbs? Are we talking AC or DC?

If you have all of your baits equally spaced on your drying wheel it shouldnt take much force to turn at all. I would try to take the wieght of the baits and shaft off of the motor shaft by supporting your drying rack on both sides with some cheap bearings

If the baits are roughly evenly spread, the motor is not under much strain. Start up is the problem, getting the mass moving. If the motor is 50ftLbs then is should have no trouble with your 15Lbs of wheel.

Consider a second hand wiper motor, they are amazingly strong. You would still need to sort out a 5 amp power supply (battery charger) and gear it down (bicycle sprockets and chain).

Yes.....that was a typo.

Mark...........I'm hoping to buy a motor that won't require me to replace it for five or more years and that's why I am looking at the more expensive motor options.

Looking at the Grainger motor it is listed as a 90 volt DC not 120 volt AC. Be sure to check the power voltage and current ratings before you buy one.

Understood. If you want something that will stand continuous use for a long time, look for a low rpm 1/4 horse 110 volt motor, and use step down gears to drive your turner. 1/4 horse motors like that are common, so they should be less expensive, and easily replaced if they ever do fail.

If you go to the trouble to build it, and it's too strong, no harm, no foul. If the motor fails after all that work, you'll be PISSED!

I was going to throw you the surplus center link also alot of good options some more powerful and less expensive. there is a huge diff between inch and foot pounds a ft lb is twelve time stronger than an inch pound.

Jed I'm sure you already know this, but for the amount of weight your turning it needs to be supported in such a way that the motor isn't carrying any of the weight. You should be able to fully support the weight with your bearings and just slide the motor into place to make the connection. That way all the motor is doing is turning the axle and not bearing any of the weight. This should help keep the bearings in the motor from wearing out prematurely.

good luck,

Ben

Hey Kjelle, didn't realize that was you! Maybe I will see you in Chicago this winter? We are planning on making another trip out that way.

Thanks everyone for the help, much appreciated.
