An electric machine is proposed, in particular a generator for a motor vehicle, having an excitation system comprised of a number of electrically excited individual poles in the stator or rotor. The stator ( ) or rotor ( ) is embodied in the form of electromagnetically excited poles ( ) which are oriented axially along the circumference and whose polarity alternates in the circumferential direction, in which permanent magnets ( ) are inserted into intermediary spaces ( ) between the alternating poles ( ) in order to reduce the magnetic leakage flux. The attachment of the permanent magnets ( ) to the stator ( ) or rotor ( ) is characterized in that the permanent magnets ( ) are each secured by means of a securing element ( ) which cannot be excited magnetically, wherein these securing elements are secured on both sides in pole grooves ( ) and one pole groove ( ) is let into the longitudinal side of a pole ( ) and one pole groove ( ) is let into the longitudinal side of an opposing pole, the pole ( ).
