The electric machine, particularly a three-phase generator, has an exciter machine ( ) in the form of a claw pole machine which supplies the exciter current necessary for the generator. The exciter machine is located to the side of the generator and has substantially smaller dimensions than the latter. At claws ( ) of the stator ( ) which face the armature ( ) of the exciter machine, permanent magnets ( ) are located in the leakage flux area between the claws. Unwanted leakage fields are contained in this way.
