Abstract
A damping structure for a rotor assembly includes holes adapted to be defined in an outer periphery of the inner rotor and in an inner periphery of the outer rotor respectively and damping elements inserted into the gap between the inner rotor and the outer rotor. Each damping element is received in a corresponding to one of the holes of the inner rotor and the outer rotor so as to absorb vibration from the outer rotor.
