| 摘要 |
The invention concerns an electrical machine, in particular an alternating current generator, comprising a rotor (3), which has at least two poles (9, 10), and a stator (7) which surrounds the rotor (3) in annular manner and has a yoke (6) which is formed from a stator core. During rotation, the magnetic flux in the stator (7) is influenced by at least one first manufacturing magnetic bottleneck (13) which is disposed at a peripheral position of the stator (7), the first magnetic bottleneck being designed as a joint (12). A second magnetic bottleneck (13) is disposed in a peripheral direction of the stator (7) offset at a spacing relative to the first magnetic bottleneck (13). The invention is characterized in that the at least one second magnetic bottleneck (13) is disposed at a spacing from the first magnetic bottleneck (13) on the stator (7) such that the second magnetic bottleneck (13) is disposed in a region including a tooth (4) which is closest to the first magnetic bottleneck (13) up to and including a position of a half pole pitch of the rotor (3). |
