ABSTRACT:
A rotor with lobes for use in a turbomachine having a rotation shaft is disclosed. The rotor comprises a rotor shell having a shell member, which is made of a sheet strip metal and having profile curvatures to conform to a required shape of the lobe of the rotor, and a connecting portion for connecting the rotor to the rotation shaft. By making a rotor from a sheet strip metal through bending process to form a rotor shell, a rotor having thin walls can be produced efficiently and economically to provide a light weight rotor of reduced inertial moment so that the startup process or shut down process can be performed quickly.
