Abstract

The present invention relates to an electric motor rotor whose buses (31) of the inductors in short circuit (3) comprise at least one linear crystal (4) shaped in analogous direction to the functional direction of electric current flow (5) and having a size of at least twice the other grain sizes of said buses (31) wherein it is arranged. The present invention further discloses manufacturing method and system of electric motor rotor.
