Abstract

A method of assembling an induction rotor includes inserting a plurality of conductor bars into a stack of disks, placing first and second end rings onto respective axial ends of the stack, thereby inserting ends of the conductor bars into corresponding slots in the respective end rings, compressing the slots against the conductor bars by impacting the end rings, and applying an electric current through the end rings and conductor bars. The compressing and the applying of current bond end rings and conductor bars together by simultaneous mechanical and electrical heat.
