The New 9 inch Advanced DC Motor Installed (Picture from underneath the car)
The New 9 inch Advanced DC Motor on the workbench
The car is driven by an 9 inch Advanced DC series wound motor bolted to the flywheel
and the original 4 speed manual transmission. The starter ring was removed from the
flywheel and the entire assembly balanced before reassembly. The upper right photo was
taken from under the back bumper looking forward (to the front of the car). Left photo taken
from above standing on the passenger side of the vehicle, the back left of the vehicle.
You can see the motor bolted to the adapter plate and transmission.
The lower picture on the right is the 9 inch Advanced DC motor on the workbench.
The car originally got built with an 8 inch Advanced DC motor but the performance wasn't enough.
I would compare the performance of the 9 inch motor to a small 4 cyl gas engine.
Just as a personal opinion, I think the 9 inch motor is probably the smallest motor you would want in a conversion.
The torque curves of a DC motor drop quite quick, so if you have a smaller motor, you already have started out with smaller numbers.
So just as a peronsal opinion, I would only look at a conversion with a 9 inch motor or larger.
AC motors don't have the same torque curve, they hold their power a lot longer.
Which is a big advanctage of AC plus a lot of the other features like regenative brakes and what not.
I have performance data on my car on the "Performance Page", you can see all sorts of data there that most people don't bother to get or show you.
