[ausev] Transmissions

[Jim Watson]

This helps alot! Especialy the motor with a universal joint connector on the
shaft. It looks like this is great for drag racing. So why don't people do
it for regular street cars for commuting to work or to the store. Let me
guess, if your motor runs at high revs it uses more power. The higher revs
and power drain the less distance you can get out of your pack.

So,... what if you mount a DC motor directly to the drive shaft with an AC
motor connected to the rear of the DC motor. My thinking on this is to
possibly create higher efficiency at higher RPMs. The two motors would not
be used at the same time. The DC would be used just for acceleration and
coupling, then the AC motor would be used for higher speeds. In a since the
switching would create a vertual transmission. I know this would mean two
separate controllers, and some crazzy wiring. But I am wondering if this
configuration may yeild greater milage because there would not be a lot of
friction causing parts in the transmission. Maybe I dont even need the DC
motor if there is an AC motor in the mix. I think the AC motors are more
effiecient at higher RPMs but they also drain more power at higher RPMs.

With your experience and knowledge about converting cars, what would you say
about this?

Thanks

Jim
