Abstract

A permanent-magnet rotor has a shaft, a core, a plurality of permanent magnets surrounded by a reinforcing element arranged circumferentially on the core, wherein the rotor comprises a core formed as a lamination core with positioning laminations and anchoring laminations, said core having circumferentially arranged longitudinal dove-tail shaped grooves. The positioning laminations and the anchoring laminations are joined to a lamination package in a way that longitudinal dove-tail shaped grooves are formed circumferentially on the lamination core. The grooves are interrupted at a certain distance by webs of the positioning laminations and permanent magnets are arranged between the grooves on the circumference of the lamination core. Said permanent magnets are held in place by a reinforcing element shaped like a plastic reinforcing cage.
