Abstract
A squirrel-cage rotor for an electric induction machine comprises a rotor body comprising a laminated assembly of steel sheets (30) axially stacked with respect to an intended axis of rotation of the rotor. A plurality of rotor slots extend substantially axially through the rotor body and are each filled with a casted rotor conductor (36). A further slot (37) is located radially outside each rotor conductor in the peripheral surface of the rotor body and extend in parallel with the rotor conductor while forming an air gap separating peripheral steel sheet portions (38, 39) of the rotor body. Each further slot (37) extends radially to the respective rotor conductor (36) so as to extend said air gap to that location.
