Re: GM to manufacture electric motors for next-gen. Two-Mode
Interesting article - it says this:
"In addition to an overall mass reduction, Engineering Director Pete Savagian claims the next Two-Mode will also have 20% more output that today’s."
That would nice!
It doesn't say who manufacturers the current electric motor - does GM contract that out?

That is a big improvement. Like I was saying on another thread, I just read the other day that the battery technology will get the tow capacities back to around 10000 pounds in the next few years.

Does the Tahoe or Volt have solid stators? I guess during an overhaul or repair they would be easier to cut down. Any weight reduction here? What about a Permanet Magnet application here in the future, maybe to costly? Several new generation jet engines like those manufactured by Pratt and Whitney use a Permanet Magnet system to provide electrical power to the engine computers as long as the engine is running. Just a thought.

Re: GM to manufacture electric motors for next-gen. Two-Mode
Both applications have bar stator motors. Where these help the most is space reduction; more compact than traditional wire-wound stators. And pretty much all current strong hybrid transmissions, including Two-Mode and Volt, have permanent magnet motors. They are costly, and rare-earth magnet sources are even more rare than lithium for the batteries. Which is why there is a big push to use induction motors more in future hybrid transmissions; lower cost and hedge against supply disruptions.

KC135R is power from the permanet magnet motor directed to the battery for charging as well, or does it supply required system power. Thanks for the detailed information.

Re: GM to manufacture electric motors for next-gen. Two-Mode
Both motors in the transmission are motor-generators, and are equally capable. They can either discharge and supply torque, or charge as part of regen braking. Just depends on the direction of the current.
