Thinking at the moment

The car is almost certainly going to be a mazda 121. Kelly is happy that it is an interesting enough car. A moke or a mini would be good but I think that I would spend more time working on the nonelectric bits of the car.

I was thinking of going with dual etek motors directly but that seems to be a bad idea. See link

The reason for going for the dual etek was for greater efficiency with the pm motor but as the curves for the etek seem to have similar efficiency to a warp series wound motor that is not really relevant

curves for etek

curves for impuse warp 9

I am leaning towards using the warp motors as they have better published data. I have to do more research as to which is the best to use.

There is a vehicle on the vehicle archives similar to what I am planning

He has kept the gearbox which I think is a wise idea.

I think that I will use a Kelly controller as it is cheaper and more programmable - see discussion in link

so - car, motor and controller temporarily sorted out. Time to go to bed
