Here are some people who seem to think it could work. And you are so wrong on the fact that I was dead set on electric. like I said it was partly to prove that it wouldnt work to my dad. like I also said there are other outside factors that influenced the electric idea. And I'm pretty sure you have no clue what any of this engine stuff means becasue you told me to just get a bungee....COskier

Quote ReplyI don't know very much about the practical applications of mechanics (only theoretical), but answer me this: The Logan guy said multiple times that an electric winch would have a bad low end. But, I have always understood that it is the opposite because gas motors have to reach their torque peak to maximize power which generally occurs at higher rpms because that is where they use the full amount of fuel that they can as they are sparking more often than at lower rpms. Anybody who can clarify?

Quote ReplySome bad info above. Electric would be cheaper and lighter and more reliable, you shouldn't be comparing horsepower, what you should care about it torque: electric motors have lots of low end torque (right from zero) ever driven a golf cart? -it might not go 60 but it takes off in a hurry. Where weight and expense comes in is in batteries, so you are left with needing to plug it in which is usually tough in public places. I imagine that you don't see any electric winches for that reason: no where to plug them in. However if you are making your own just to use in your back yard with an extension cord from the house, then you're probably in good shape.

its not maintenance from the standpoint of changing the oil and sparkplugs (like you would with a gas motor), it's from an operating standpoint. like i said before you're either gonna have to run it off of a generator or batteries, either of which is going to cost you more than running a gas winch (which has better low end torque anyways).
http://www.ultimatewasher.com/small-ac-electric-motors.htm here's your other disadvantage: weight. a 7.5 horse electric motor weighs almost 90 lbs. My 7.5 horse honda can't weigh more than 40 lbs. so whoever told you they would be lighter was sorely mistaken.Where did you hear electric motors have less torque then gas? From what I understand electric motors have MORE torque then gas motors.
Heres a discussion I found about it

I still do not see why some people are making that big of a deal about it. Plus there are so many more things to consider when going between gas and electric. The HP isn't the same. a 3hp electric motor has a different amount of power than a 3hp gas motor.
