Abstract
A rotor for a dynamoelectric rotary machine includes a rotor stack, a plurality of permanent magnets, and a binding designed to fix the permanent magnets to the rotor stack, said binding including a binding thread. The permanent magnets each have at a surface of the permanent magnet a shape deviation designed to receive the binding thread and to comprise a conical thickening and an indentation, with a height difference between a highest point of the thickening and a lowest point of the indentation being at least 2% of a thickness of the permanent magnet and at most 20% of the thickness of the permanent magnet.
