Default 2 water cooled ac motor kits

The single version looks good value. Is it powerful enough for a small EV car conversion based on a Westfield/Lotus 7 type kit?

Maybe.

It's rated for 18kw nominal which is about the same as the DC motors a lot of us use in our cars. Figure in that it is (from what I can tell) an AC motor and you have a lot more high-end torque.

On the other hand, it's rated at 48v, with apparently higher end ratings available? For good performance and range you'll probably want a lot more than that.

Bottom line- it's probably a good idea to do a little more research so you can better define your requirements.

water/liquid cooled ac looks to be the future.

If anyone else sees a suitable water/liquid cooled ac unit post it please!

This uses a more powerful version of the same Curtis controller, running at 96-108 volts 550 amps, 8 inch air cooled AC motor:

I'm thinking of using it in my Fiero conversion.

are you going to go for the ac-31?

have they mentioned any news about that new, larger, motor they are working on...

Would be nice if it was a 200V capabe setup!!

Yes, unless I procrastinate long enough that the AC 50 is ready.

No news, they said a few months, but it will still only run 96-108 volts. The Curtis controller seems to be the limit.

the curtis we are talking about tops out at

108V and 550A right? so thats 59.4 kw maximum (80hp)

So do you think the AC-50 will be able to extract that power and maybe hold it longer (more rpm) than the 30/31?

would be nice to see a power graph once they are done..

I guess They say it's the same diameter as the AC31, 8 inches, but longer, so I'm not exactly sure how that translates into more power.
