The invention relates to methods for manufacturing a rotor () for an electric machine (), having the following method steps: a) manufacturing a magnetic element () by bonding permanent magnets ('&#x2033;) by means of a first adhesive, each permanent magnet (&#x2032;&#x2033;) having a side with a magnetic North pole (N) and a side with a magnetic South pole (S), the permanent magnets (&#x2032;&#x2033;) being arranged during bonding such that the sides of the magnetic North poles (N) or the sides of the magnetic South poles (S) form a common underside (&#x2032;&#x2033;) of the magnetic elements (), the first adhesive having a hard consistency in the cured state; and b) bonding the underside of the magnetic element () to a yoke () by means of a second adhesive, the second adhesive being soft and elastic in the cured state. Furthermore, the invention relates to an associated rotor. The invention permits rational manufacture of a rotor having a permanent magnet for a machine, the permanent magnets being integrally fixed to the yoke of the rotor with high reliability.
