Abstract (en)

[origin: WO2022106532A1] A rotor for an electric machine has a laminated core having a plurality of laminations which are arranged one on top of the other and into which permanent magnets are introduced in recesses. The recesses are delimited radially outwardly by a delimiting wall of the lamination, said delimiting wall being adjoined in the circumferential direction by radially thinner delimiting connectors. The limiting connectors lie radially inside the rotor radius and have a radial distance from the rotor radius.
