That's neat. Thanks for sharing.Bob said:There are lots of excellent photos on these two discussions:

That was interesting. Thanks for posting it.ElectricEddy said:https://www.youtube.com/watch?v=4GG3QRPGlPc Hope this helps.
Woah. Didn't know about this until DaveInOlyWa posted it elsewhere.ElectricEddy said:https://www.youtube.com/watch?v=4GG3QRPGlPc Hope this helps.

The induction motor produces more torque (performance) but requires more complex electronics,
i.e. current is "induced" into the rotor from the stator. The Leaf's motor is a brushless D.C. motor
similar to what's used in a computer hard drive. The induction motor RPM output can be greater
than the permanent magnet motor used in the Leaf. The Volt and the Tesla both use an induction motor.
