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…
Not a lot of substance on the technology. We’ve had non permanent magnet motors since Nikola Tesla invented induction motors. They were one of the big driving forces behind making mains voltage 3phase AC.
We also have switched reluctance motors which use a different operating mechanism than induction, but are still non permanent magnet motors.
So did they just make a motor using one of these existing, well understood technologies? Or did they come up with something new? This article certainly doesn’t tell us.
