[DML] Re: Second Major Milestone in the Electric DeLorean

As you probably know, horse power ratings for electric motors are different  
than gasoline engines.
Here’s an explanation from Austinev.org:

“Electric cars are driven by large electric motors usually rated between  3.5 
and 28 horsepower. For those accustomed to gas engines, this may not seem  
like much power, but the rating systems used for gas engines and electric  
motors are so different that the numbering system is almost meaningless. Gas  
engines are rated at their peak hp, electric motors are rated at their  continuous 
hp. The peak hp of an electric motor is usually 8 to 10 times its  continuous 
rating.”
That being said... here are some specs: 9.25”  diameter, series wound DC 
motor, Weight, approx. 156 pounds, 32.3 HP (72 Volts,  335 Amps)*, 70 Ft. pounds 
torque*, 5,500 RPM's

Now I will be able to put a maximum of 170 Volts  at 1000 Amps into the motor 
for short periods of time, so the peak HP and  Torques should be a lot higher.
 
The 11 inch motor is a lot heavier, bigger and  more costly... however maybe 
next time....

Hey  Doc,

What type of output specs do you expect with the WarP
9?   What was the consideration to go with the 9,
instead of say, the  11?

Great work!  Can't wait to see  more!
