Motor Speed
-------Motor Efficiency
---------------Controller Efficiency
------------------------System Efficiency
2000 89.0% 94.4% 84.0%
2000 85.0% 95.3% 81.0%
2000 80.0%
3000 89.0% 94.4% 84.0%

3000 82.0%
4700 87.0% 95.4% 83.0%
Thats couple motors thats why different efficiencies at same rpms however even the lowest one.. still over all efficiency over 80%.. much better than 12-17%

usually volts and cost increase linearly.
DC systems are pretty much entery level systems. Not many options, not much wiring...not many volts...
AC is the advanced system that allows you to use it for regenerative brakes and so forth.
Ac is where the power is at.

Right, because all electric cars are slow.

Agreed. I seriously considered building an electric car several years ago. When I realized all I could afford was a PWM regulated DC motor and lead acid batteries, I gave up. High-current inverter drives (for AC induction motors) and high(er) energy density batteries are still too expensive for me.

If i were to under take an electric,No conversions.Ground up build I think would the only way to go,most gas cars are too heavy to start with.Sort of looking like a Locost but really quiet and stupid fast.I admit Ive forgotton too much of my initial electric research.
