A synchronous machine formed as a generator for a motor vehicle has a stator, a rotor, an excitation system composed of a plurality of electrically excited individual poles provided in the stator and the rotor and formed as claw poles excited by a joint excitation coil, and a stray field compensation device arranged in free spaces between the claw poles, the stray field compensation device being formed as an additional winding through which current flows and which surrounds the claw poles so that an axial current direction changes from one free space to another free space and a current to neighboring claw poles produces an additional flux which supports a main flux and counteracts a stray flux.
