Abstract: In a method for producing a rotor for a synchronous machine suitable for a rotational speed of more than 1000 r.p.m, a plurality of electrically conductive rectangular sub-conductors are loosely joined in parallel to one another lengthwise to form a conductor. The conductor is wound so as to form a winding and thereby form an exciter coil. Directly after winding, the sub-conductors of the conductor are continuously soldered together while the sub-conductors are positioned and/or held together by a forming facility, so that the exciter coil is solid and the conductor rigid.

Abstract: A component designed to form a rotor for an electric machine includes a shaft, and an active part which is disposed in concentric circumferentially surrounding relation to the shaft. The active part has a radially inwardly open slot. A leg is connected to the shaft and has a tip which points radially outward from the shaft and is received in the slot of the active part. Further received in the slot of the active part is a first end of a connecting element. A fastening element secures the connecting element in a region of a second end to the leg to thereby establish a form-fit connection of the leg and the connecting element to the active part.
