A synchronous machine, in particular a motor for a motor vehicle has an excitation system composed of a plurality of electrically excited individual poles in a stator or a rotor, preferably formed as claw poles excited by at least one joint excitation coil, wherein for compensation of a magnetic stray flux in the intermediate spaces between the mutually oriented and alternatingly nested claw poles, the permanent magnets are inserted on the pole plates on the ends of the stator or rotor, so as to facilitate and simplify the insertion of the permanent magnets required for compensation of the stray flux and to improve their compensation action.

A synchronous machine, in particular a generator for a vehicle, has an excitation system with a plurality of electrically excited individual poles in a rotor, preferably in form of claw poles excited by at least one common excitation coil, in which for compensation of a magnetic stray flux, in the free spaces between the axially oriented claw poles permanent magnets are inserted at the axial ends of the pole plates of the rotor, so that the permanent magnets are supported by a holder against centrifugal forces and held by it, and therefore an especially simple and inexpensive holder is formed which considerably simplifies and facilitates the insertion of the permanent magnets.
