Magnetic coupling

Magnetic gearing is also being explored for use in utility-scale wind turbines as a means of enhancing reliability.

[6][5] The other design maximizes torque and resists the consequential axial load with a mechanical thrust bearing.

If the load on the driven component becomes too large, the two parts may slip out of sync and end the transmission of torque.

This avoids damage to the system, protecting both the motor from excessive loads and the driven component from deformation.

The combination of these transmission methods and different mechanical geometry can realize a wide variety of orderly motion in three-dimensional space.

This is particularly important if the pumped fluid or gas is corrosive, toxic, flammable, explosive, acidic, alkaline, or otherwise harmful.
