A method for mounting permanent magnets that form magnetic poles on a permanent magnet support surface of the rotor of an electric machine includes the steps of forming a mold by the placement of a mold part against the support surface in such a way that the mold cavity of the mold is bounded on one side by the support surface inserting a permanent magnet into the mold so that the inserted permanent magnet is held in the mold in a desired position with respect to the support surface, and filling the mold with a thermosetting adhesive in such that the adhesive bonds the permanent magnet with the support surface and completely fills any spaces formed between the permanent magnet and the wall of the mold cavity.
