An induction motor rotor is manufactured by assembling copper end ring laminations 30, 35 on each axial end of a core assembly 15 with slots 20, 34 aligned and copper rotor bars 40 in the slots and induction brazing the ends of the copper bars to the copper end ring laminations. The forming of the end rings by laminations greatly reduces machining and scrap; and the use of induction heating reduces exposure of the core assembly to the high heat of brazing.
