摘要:
The invention relates to methods for manufacturing a rotor (14) for an electric machine (13), having the following method steps: a) manufacturing a magnetic element (8) by bonding permanent magnets (1, 1′, 1″, 1′″) by means of a first adhesive, each permanent magnet (1, 1′, 1″, 1′″) having a side with a magnetic North pole (N) and a side with a magnetic South pole (S), the permanent magnets (1, 1′, 1″, 1′″) 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 (3, 3′, 3″, 3′″) of the magnetic elements (8), the first adhesive having a hard consistency in the cured state; and b) bonding the underside of the magnetic element (8) to a yoke (12) 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.
