Abstract:
A combination of a rotor and a stator assembly, the stator assembly having a first part and a second part, the stator assembly further including a pair of end plates, the first and second parts being generally concentric, the rotor being rotatably mounted in the stator assembly, the combination further including means located between and spacing apart the first part and the second part of the stator assembly to provide a generally annular space therebetween, the means being adapted so that the annular space remains substantially unoccupied, and wherein the means located and spacing apart the first part and the second part includes at least three elongate resilient damping elements each of which extends generally in an axial direction, each of the elongate resilient damping elements having a tubular cross-section, the elongate resilient damping elements being spaced apart between the first and second parts and extending along a length of the stator assembly between the pair of end plates.
