Patent ID: 7122932

Claim:
A rotor for an electrical device, comprising: a rotor core having a core cross-section and a plurality of rotor slots extending through the rotor core generally transverse to the core cross-section; a rotor shaft extending through the rotor core generally transverse to the core cross-section; first and second end members disposed at opposite ends of the rotor core, each end member having a plurality of end slots cooperative with the plurality of rotor slots to define a plurality of rotor channels extending through the rotor core and the first and second end members and having a flange portion located radially outboard of the plurality of end slots; and a plurality of electrically conductive members disposed in the plurality of rotor channels, wherein each electrically conductive member includes external portions that extend beyond the rotor channel and an internal portion housed within the rotor channel, and wherein the external portions are joined by a weld to the corresponding end member to electrically couple the conductive members to one another, wherein the first and second end members are held on the opposite ends of the rotor core by the electrically conductive members.
