Re: Electric Seven

Methinks we need more info! What a great idea.




Starting handle looks a bit short, though.

Another electric Seven....


That looks super interesting - Curious how the gearbox really functions though without a clutch? Do you simply pick a ratio when stationary and go? I guess that keeping the original gearbox also ensures it is not a silent ride?

In all seriousness though, as battery technology gets even better than it already is, this sort of thing is probably a viable option for old jalopys....?

Re: Electric Seven

Alex,

this particular car was a stage prop for a theatre. All it was required to do was come on and off the stage with characters sat in it.

A curiosity, I like curiosities a lot.

The full story appeared in one of the A7CA Mags I produced - I will look it up and post for you.

Re: Electric Seven

I know a very little, a dangerous place to be...but...as I understand it...

The flexibility of modern motors and the advances in power controllers make the gearbox unnecessary.

With a bit of understand one could make use of the braking effect of the motor to aid coming to a halt.

First thoughts would suggest that putting the motor directly at the end of the torque tube and then placing the batteries under the bonnet would aid weight distribution and not overly increase unsprung weight.

My son then explained that there are motors that effectively could replace both rear hubs. He tried to explain how a differential effect could be programmed.

At this point I lost the plot but the point is that it is quite do-able.

Not sure whether I want to drive along listening to groans, creaks and rattles unaccompanied by the sounds of mechanical harmony that we are used to.

There's nothing new about hybrid or electric cars...

Re: Electric Seven

Well this post certainly caught my eye during my occasional lurking on this forum.
I am seriously considering a full electric conversion on my '36 Ruby as this winter's project. After some preliminary calculations it would seem quite feasable to achieve a similar performance to the original engine.
Does anyone know of another road going electric seven?

Re: Electric Seven

Have a look around this website...

and ponder this lot...

It seems feasible enough if one's ambitions are reasonably low key.

Re: Electric Seven

Seems like an interesting experiment to be done on a bare chassis project. Perhaps not an existing running car, unless it was all easily reversible.
