New SAE papers published on Voltec design

[WopOnTour]

This week was the SAE World Congress and a number of General Motors engineers, employees, various suppliers, and co-op grad studens delivered papers and presentations on various aspects of the Voltec design.

In fact, the number of papers brought forward by GM this year set an all-time SAE record!

I'm sure more than a few of you would find these papers very interesting and as enlightening as I have. (and quite resonable $$ especially if you are an SAE member)

Below is a partial list

ENJOY!

I wonder how many (and which ones) of those are in this book?

I just got this SAE book and skimmed a few of the 14 or so technical papers in it.

Wow, that sort of redefines "information overload", LOL. We knew that the Volt was a technological breakthrough, but this really drives the point home. Thanks.

Hey, what sort of motor is is the Volt?

It's been widely reported that the Volt has a three-phase AC induction motor. But the"Voltec 4ET50" paper says the motor is "permanent magnet AC synchronous". That is not the same thing.

This makes a difference because a permanent magnet motor uses rare earths, and an induction motor doesn't.

So which is it?

Anybody have any insight here?
