Two great minds in permanent-magnet-free motor design are fusing their know-how to create an even more capable inductive electric motor. Mahle and Valeo have teamed up to introduce what they call the Inner Brushless Electrical Excitation (iBEE) system, a form of e-machine that eliminates the need…
Sounds like old tech with high tech control.
This is very similar to why Honda Accord engines from 20 years ago can be tuned and turboed to make 5 times the power they did when new. Control and feedback sensing is super important, and computers are finally cheap and powerful enough (when built reliably and redundantly) to do it.
