Alternator with exciting means arrangement

An electrical machine, in particular three-phase generator, having a stator (21) secured in a housing, having a claw pole rotor (23) that has an exciter winding (28) and is secured to a shaft (13), and having a repeater (29), laterally adjoining the claw pole rotor (23), with primary and secondary windings (30;

• 31)that each disposed on a respective core (36,41, 47;
• 35,42,48) of soft magnetic material and are magnetically coupled to one another via an air gap (38), and the repeater (29) transmits an exciter power to the exciter winding (28), and the repeater (29) is disposed between the claw pole rotor (23) and a bearing plate (17) that closes off the housing (10) of the three-phase generator, the primary winding (30) is disposed together with the associated stationary core (36, 41, 47) on the bearing plate, and primary and secondary windings (30, 31) comprise band material.
