Patent ID: 8823239

Claim:
An electrical machine comprising a rotor and a shaft, the rotor comprising a plurality of plates, wherein the plates are premounted on the shaft by a joining operation as one of individually, a plate assembly, and a plurality of plate assemblies, and wherein the plates and plate assemblies are at least indirectly connected to the shaft, comprising: a resilient lug configured for each plate assembly on at least one plate to at least indirectly fix the plate assembly to the shaft, the resilient lug for each plate configured to have a substantially uniform deformation relative to the resilient lug for other plates; and a centering lug configured on at least one plate and at least one additional plate to at least substantially radially center the plate assembly relative to the shaft, wherein substantially radially centering the plate assembly relative to the shaft results in the substantially uniform deformation of the resilient lug for each plate, wherein if the rotor is constructed from a plurality of individual plates, each individual plate has at least one resilient lug and at least two centering lugs arranged radially oppositely to each other.
