ABSTRACT:
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.
