Permanent magnet and method for producing a rotor of a dynamo-electric machine having such permanent magnets

A method for producing a rotor of a dynamo-electric machine, the method comprising:

• forming a magnet pocket and flux barriers in an axially extending, circumferentially closed recess of a laminated core for receiving a permanent magnet in the magnet pocket with two opposite flux barrier sides facing flux barriers, with a delivery side and a thrust side on two opposite sides and facing end faces, and with an air gap side and an axle side as two magnetic field sides;
• forming portions of the delivery side and/or adjoining regions of at least one of the air gap side and the axle side located in a magnetic flux with a curved or fluidic configuration in at least one section;
• adding an adhesive to the delivery side of the permanent magnet;
• and
• pushing the permanent magnet with the delivery side in front axially into the magnet pocket such that the adhesive is distributed via a gap between the air gap side and the magnet pocket and a gap between the axle side and the magnet pocket without wetting the flux barriers, thereby adhesively bonding and burying the permanent magnet in the magnet pocket.
