Hi Folks,

A friend of mine has a Kewet (possibly smaller than your mini), and she replaced the old worn-out DC motor with an AC motor from HPEVS. The motor is the AC50, and can be ordered from the factory with a transaxle. She was able to fit it in using Geo Metro drive shafts, with no machining needed.

Cheers,
Peter

That would be something for me. How can one order it? All pages on their website say “ This Page is Under Development
Check Back Soon “
Can’t even find the e mail address.

Well, not quite all. Not sure what the deal is. However, they do have phone numbers (how 20th century!) on their website tho.

I'll see if I can locate an email address for you. Another possibility is for an EV vendor near you to order it...not sure who would be best for Ireland.

Cheers,
Peter

I'd go for the Think! drivetrain. I am using a chain drive and a simple DC setup because of cost and simplicity but expect it to be noisy.

I think you would turn it around and upside down - then all of the gear loads would be in the right direction

You right mate. I guess starring at computer screen all day long makes me see the world in only two dimensions.

I was just reading through Caspar's build thread and noticed there's a slight problem with the Think system. Top speed for the Think was limited by the controller to 90 kph, but with 10" Mini wheels that drops to 70 kph.

Caspar, if you're following this, did you manage to find out how to increase the controller's rpm limit?

Is this a single speed transaxle? What ratio?

[MalcolmB]

It sounds like the Azure Dynamics system. Fixed ratio of 10:1.

I still have the setup from my Mini pickup conversion - which was based on an automatic Mini gearbox. We (Paul Compton and me) removed all the insides, leaving just the diff & final drive pinion. Paul then made a shaft and adaptor to bring the shaft out of the side where the transfer gears used to be, put the motor on top and coupled it up with a big toothed belt.
Worked ok, could do with having bearings on both sides of the belt

The gearbox is still here outside my garage, even the motor is still here & looking for a new home! Fancy a trip to Cardiff?

Would be nice to see another electric Mini, especially if it's got lithium cells....
