摘要： A synchronous machine, in particular a generator for a motor vehicle, has an excitation system with a plurality of electrically excited individual poles in a rotor, preferably in form of claw poles which are excited by at least one common excitation coil, wherein for compensation of a magnetic stray flux, permanent magnets are inserted in free spaces between the axially oriented claw poles on the pole plates mounted on the axial ends of the rotors, and the permanent magnets are supported by a holder against centrifugal forces, so that the insertion of the permanent magnets is simplified and facilitated by a simple and inexpensive holder which reduces parts and mounting expenses.
