Due to the non-contact nature of these devices, they are inherently tolerant of overloading. For synchronous devices, an overload leads to a ratcheting effect as like poles repel one another. If the vibration does not cause damage to the system, the device will either recover or reset the couplings or can be reset by linear couplings when the load is returned to normal. For dc devices, Class II permanent damage may occur as a result of eddy current heating. The amount of damage and heating is proportional to the amount of time the overload is active. For short durations, the system simply recouples.
