ROTOR FÜR EINE ELEKTRISCHE MASCHINE, SOWIE HERSTELLUNGSVERFAHREN EINES SOLCHEN
摘要:
The present invention relates to a rotor for an electric machine, comprising a core made of metal lamellar sheets (1), which are disposed on a motor shaft (2), wherein the metal lamellar sheets (1) of the core are made of a two-state steel and have a low relative permeability in an inner region (3), in which the motor shaft (2) is attached to the metal lamellar sheets (1). Furthermore the invention relates to a production method of such a rotor.
