‘Game-changing’ electric motors could power aircraft, page-3

Yes, I posted this article when it came out:

But this is new from magniX:

Another magniX technology is a high-torque magnetic coupling which is said to weigh about half as much as rival technologies. The 172mm-diameter coupling weighing 10kg can operate at speeds of up to 5,000 rpm and transmit up to 500Nm of torque in or out of a sealed environment without needing a mechanical connection. It can be retrofitted to existing applications that use magnetic or non-magnetic couplings.

I also wish they would give more info about their superconducting generator.

Anyway, more companies using permanent magnet motors is good for the industry as a whole.
