Abstract
In a slipring-less generator having magnetic coupling rotors embodied in claw pole fashion, it is proposed that the two additional air gaps, which are embodied by annular magnetic flux guide elements, are extended obliquely at an angle to the longitudinal axis of the generator and extend at least in part above or below the field winding, so that with a corresponding enlargement of the further two air gaps present in addition to the working air gap and a resultant reduction of magnetic voltage in these air gaps, either higher power or a shorter structural length with a corresponding weight reduction is obtained.
