So here is what I learned about motors from this site. I wanted to post a quick reference so newbs (like myself) do not have to sort through the sticky page.

When looking for a forklift motor:
Get a series wound motor because they have very high torque and handle abuse (over volting) a lot better.
Know the difference between a Spex motor and a Series wound.
When dealing with series wound forklift motors go for higher voltage. (36V may require advanced timing.)
Hp does not directly represent torque (although it does have a factor in its equation).
Get a class H insulation if possible (makes your motor last longer)
Get a motor around 150lbs (Wouldn't risk a motor that's too light, it won't have the oomph you need. a few extra pounds is A-o.k. but a significant amount of extra pounds limits your range)
Get one with a male shaft
A keyed shaft is easier to work with but you can still work with a spline shaft
Try and get the coupler that goes on to your motor when you buy it/rip it out (saves you $$ and time)
When looking for a different motor:
Ac is not the way to go for your first conversion (or do i just have low expectations of myself?)
You can tell if a motor is AC if it is a 1 phase or 3 phase motor
Pancake motors are usually not good candidates for car conversions. (Yeah you saw the one on ebay. They overheat easily)
Golfcart motors are seldom powerful enough for a conversion
Motors specifically made for EV conversions are the best but its gonna cost you.
You do have to look at many factor such as volts, amps (which gets you Hp). Torque is nice to know. Continuous Hp. So many factors!!!
If there is any more helpful hints I'll be happy to add them
Anywhere where the "metric-sytem" is used; there is no use of the word Horse Power, it is a forbidden-word in the Euro-Union, to the extent, if a student doing an exam uses the word ,horse-power he automatically voids his answer!!!!!!!!!!!! Some examiners were willing to fail your whole "paper" in Europe during the "changeover" to metric.

The demon word - Horsepower - is frequently used - the only problem is that there are lots of different -horsepowers-, SAE, DIN, PS

I have taken numerous European technical papers - and set a few - and I have never heard of anybody being penalized for using the word - horsepower

Mind you if you tried to answer a technical question in horsepower instead of Kw I would have marked it wrong - just as I would have if you answered a distance question in Roman miles

Have you ever tried to do any serious engineering work in the Imperial system?
It's bloody hard - Rotary Slugs for example

during the "changeover" to metric.

I remember the UK as the last country in Europe to "changeover" - but that was over forty years ago!!
I was threatened in England just after the "changeover" to metric, just before starting a Marine Engineering exam, and again in Canada when starting a "Stationary Engineer's" exam also. But; I guess nobody in both countries "cares a damn" which you use theses days!! In England most "speed signs are in both! Here in Canada there was talk about doing the same, posting in both MPH and KPH.... In a lot of calculations it is easier to use metric, but that is the only advantage I can see.
