New application for motors and drives
(OP)
I just thought this interesting and worthy of sharing.
Makes a lot of sense to me, but I'll admit my bias

Maybe they can even use dynamic braking.

This is the motor they are using, 17 phase, 1-6 span. They got a great demo about the technology. Way over my head but I liked the animation.

And could you get enough traction to move it? the nose gear on most planes is lighly loaded, yes?
What powers the thing? Is the APU on most plane sbig enough?
Heres one.

Perhaps they would go for 5MPH to get them to and from gates but 15MPH taxing would probably go for the engines.
I think I've seen planes back away from gates with no assistance and no engine reving. I suspect hydraulic motors using the already vast hydraulics available and a 10 pound hydraulic motor.
RE: New application for motors and drives
I had two thoughts.
The first one was along some of the lines already mentioned; A good idea but is it the best technology to move a large airplane. Wheel motors, or hydraulics perhaps.
The other thought was WOW.
This may quietly disappear or it may be the next big step after VFDs and build on the capabilities of the VFD. With a VFD, we have a system that can vary both the voltage and the frequency of a motor. With this system and VFD technology we have a system where the VFD based control can seamlessly reconnect the internal winding groups in the motor as it is running.
I think that torque will still be pretty much dependent on frame size, but with the reconnection you can stay close to the optimum frequency regardless of the speed. Just reconnect for the appropriate speed range.
It will be interesting to see if the benefits outweigh the complexity.
yours
