Effects of Running Higher Power through Kollmorgen Motors

[Logic11]

There are some existing magnetic gear setups.

If designed properly, the gears have nearly zero loss and zero wear. Most of the systems involve both attraction and repulsion and the gears will "slip" if the load gets too high, which creates a safety feature. No broken gear teeth.

Thx fetcher, I saw them.
It's great that too much torque just means slip, not destruction.
But
My think is why re invent the wheel:
A stock gearbox with repelling teeth would/should reduce friction and wear considerably!..?

The teeth could even be north on one side and south on the other (stock round magnet) as long as the box was put together so they repel.

I don't think you can get enough magnetic repulsion between teeth to make a difference. The teeth will touch with more than a slight load. Also, when two magnets are repelling, the flux drops way down in the gap. When attracting, the flux is high. More flux = more force.
