摘要：
The electrical machine, in particular a three-phase generator, has a stator (21) secured in a housing (10) and a claw pole rotor (23) which is secured on a shaft (13) and has an exciter winding (28). Between the claw pole rotor and a bearing plate (17) that closes off the housing, there is an electrical repeater (29) for exciting the exciter winding (28). The primary winding (30) is disposed along with the core (36, 41, 47) on the bearing plate (17). The primary and secondary windings (30, 31) of the repeater (29) are disposed between the bearing plate (17) and the claw pole rotor system (23); the primary winding (30) is disposed in a stationary core (36, 41, 47), and the secondary winding (31) is disposed in a rotating core (35, 42, 48), and the windings are coupled via an air gap (38).
