Re: Questions About Electric Cars
The cool thing about that eCOPO is the 600 ft pounds and 700 hp is instant.
Induction motors do not create maximum torque under locked rotor conditions (0 rpm), and they create no power at 0 rpm either. (nothing else makes any power at 0 rpm either) The torque curve of an induction motor at 0 rpm starts out at some value below the max torque it can make, and goes upward at some rate or another as rpm increases (depending on several facets of its design), and peaks close to synchronous rpm. Synchronous rpm in common terms is the speed at which it "wants" to run under no load. As motor speed further increases past the peak torque, torque very quickly drops to zero. The zero crossing occurs at synchronous rpm. Synchronous rpm is determined by two things: The number of magnetic poles in the rotor and the frequency of the voltage powering the motor. You can get lots of different behaviors out of a motor with a variable frequency drive, but full power or torque at 0 rpm is not one of them.
