2.6kw is suitable for a moped. I doubt you'd be able to push a car up to moped speeds with that motor.
ok thanks for the help

one question what should be the correct kw for a 2k car?

I found another forklift locally
2001 Toyota 5FBE15 electric forklift. 3000 lbs capacity

the load motor is rated 36v/48v @ 6.1kw/8.0kw
so if I power to 48v it will be 8.0kw
its that ok??
its there a chart that I can reference to?

OK that motor will be 8 kw at 48 volts - and will run all day at that
BUT it will almost certainly be at about 1400 rpm

If you put that in a car it will have a top speed of about 30 mph

But you don't do that!
What you do is run a 150 volt system - and feed that motor with 500 amps

That will give you a 100 hp - and it will feel like a lot more

If you were to hitch a BIG trailer and run at that power continuously you would melt the motor
But you won't - you will use the 100 hp to accelerate and at the top highway speed you will be using about 20 kw

Which sounds like too much - but the motor will be running at 4,000 rpm and will be only drawing the same current as it is rated at with three times the cooling air flow

Unfortunately it's not going to be any use for you!

The drive motor will be in a huge funny shaped metal casting - and the pump motor will have a female spline drive shaft

Try and find a four wheeler forklift

ok bad news
but if I can get a machinist to work out the female spline toa coupler to the tranny
this could work?

if not, I found this fork lift near Miami, looks to nice to hack-it and its a lot of money @2k but it has good batteries and the charger that I can scrap for $$
4 wheeler for 4,500 pounds

https://miami.craigslist.org/pbc/hvo/d/west-palm-beach-hyster-2006-electric/7107702793.html

its the 48v model
says AC drive motor 24.7hp 18.4kw
AC optional 12.5hp 16.8kw or DC standard pump motor 14hp 16.8kw
here are the specs

AC adds massively to the complexity - the advantage of a DC forklift motor is its simplicity

If I wanted to go AC I would go the crashed production EV route
found a motor today

11'' diameter
16'' long
about 230 pounds
from a 4500 pound forklift 48v
cant read the id plate

how do I upload the pictures??

... are there posts missing from this thread?

I swear there's as missing exchange here where I tell the OP how to use IMGUR, and then re-post his links afterwards.
