ABSTRACT:
According to the invention, a rotor is provided having a cylindrical core and a protective can closely fit and secured with the core. The core is provided with two axially spaced, annular reliefs spaced inwardly from points of welding which secure the can and core and connected by at least two circumferentially spaced, axial reliefs. To effect removal of the can, a cutting tool is extended through the can along the extent of the reliefs. With the cuts completed, access sections are defined and are separable from the core. The remainder of the can, including the weld material, can be machined off using conventional techniques.
