Great job! How does the car feel to drive in comparison with the original IC Engine - in terms of acceleration, power curve & speed? Also, hill climbing ability? I guess, what I'm really asking is, is 20kW sufficient for this size vehicle, for it to be useful & nice to drive?
Hi thanks! The mass is quite spread to the edges of the vehicle with the battery structure. Unfortunately this is difficult to work around given limited spacing to position batteries other than the front and rear. The 18kW of power I recorded at present is enough for town driving. Wouldn't be good for hills given the weight of the car (about 1300kg). Power curve will be more even and consistent, acceleration is quite slow at the moment unless you drop the clutch :) Cheers
Did you think of putting the battery down the now empty tunnel to ballance out the weight? What part of nz are you in and are you in the mr2 club? Would love to see this car in person.
These particular cells have very good life left in them. I had them running on my ebike for a year with less than 5% degradation, with 30 - 60 minute discharge and 2 hour charge cycles. I have since rebuilt to improve the designs safety. Cheers
Hmm. Thats a hard one to answer - as I have never taken the motor apart before. There is a guy in Australia (I think by the name of AusEmoto) that has done some investigation on it. The motor works, and at 20 kW the heating is rather minimal after a short drive - although I personally believe (opinion only) - a much greater power density could be achieved by a dual magnet disk rotor single stator design, than dual stator and 1 magnet rotor in the design due to wasted flux out the opposite sides of the 2 stators. I have a feeling the cooling ability of the motor is better in the design due to the stators being further out, and the end faces being in direct contact with the stator, but don't take this too seriously as I am in no way qualified in electric motor construction and design. Pretty sure there are much better motors in this axial flux design for power density that are commercially available. Cheers

We need top speed and 0-60m/h

Hi dude , hows the car going ? would you recommend the golden motor?
Lovely

Yes I did. My engineering skills limited me. I'm not sure if I am in any MR2 club, but would be keen! Wellington based currently.
Cheers
I really like it. How fast is it with that battery?
80km/h (limited by maximum voltage)
Goldenmotor 20kw?
Yep
Damn good job. How many hours before them little battery's go bad? They only last about a year in my vape......

Is this your own design, or an aftermarket kit? Looks fun!
Yes all custom design with available parts.
Cheers
Nicely done! What do you think of the HPM 20kW, Stefan? Decent build quality?

What’s the reserve price on Trade Me😜
Haha bit soon for this one!
EVClassic has a listing though currently -

Good on’ya brother, keep up the good work🤙🏽
Keep updating please
i like the cuts
just make them quicker add some grunts
then you will become how to basic 2
