Hook 'em together and see which one wins.

Hoo ha! That's a good one

omg wow i'm so jealous... i really want an EV for my short trips ... oh man when I visit Toronto can I see this baby? Maybe even encourage me to work on my own EV! Man if I can build a simple EV that would seat four and would give me AT LEAST 30 km range per charge oh man I would be drooling all over it.

Your experience is truly appreciated! I hope your EV runs! Man now your tanks will truly rock because you'll never have a cold trip ever again in your Gas Geo!

SUPER JEALOUS!!!!!

Sure thing, Phil. But I'm closer to Ottawa than Toronto You'd have to give me about 10 days notice to drive it to Toronto!

You know there's a pretty active EV association in Vancouver. You could probably see some cars and get advice: http://www.veva.ca

May not work out that way. Just like the bicycle cargo trailer , the EV is going to displace even more local driving where I consistently get better MPG than highway trips. The Blackflea tank averages are probably going to go down when the ForkenSwift goes on the road.

It couldn't be much cooler if it removed itself. In fact, if you ... er, um, forget what I said, bad idea.

Then we reassemble and test the "new" CCW motor RPM against "stock" CW RPM of sister motor - to determine if the brushes are neutral or not. Hoping they are (it'll save time). Should have compared RPM of both motors in stock form before all this, but I wasn't being very scientific.

Exactly what I was thinking (I know, big help ain't I).

It sounds great, I'll be watching.

Well, we tested the motor today in both

I read that it's actually possible to overspeed series wound motors if you run them w/o a load even though speed limits current flow. I would think the comm timing could have a huge effect on how the field and armature fluxes interact. I have no personal experience though.

[MetroMPG]

You're right about overspeeding a se

The EV list folks seem to be leaning tow
