Abstract

Abstract Translated from German Die Erfindung betrifft einen durch ein homopolares Magnetfeld vormagnetisierbaren Läufer einer elektrischen Wechselpolmaschi­ne. Eine Optimierung des Feldschwächungseffektes wird dadurch erreicht, daß der Läufer im Inneren in vorwiegend radial ge­richtete Magnetflußbahnen (5, 10, 18) unterteilt ist, in denen induzierende und homopolare Magnetflüsse (Pfeile 7 und 6) parallel überlagert verlaufen und die vorzugsweise mit paral­lelen Flanken ausgebildeten Magnetflußbahnen (5, 10, 18) mit solchen Querschnitten versehen sind, daß sie durch die induzie­renden Magnetflüsse (Pfeile 7) allein bereits bis zum Sätti­gungsbeginn magnetisiert sind. The invention relates to a rotor of an alternating electric pole machine that can be premagnetized by a homopolar magnetic field. An optimization of the field weakening effect is achieved in that the rotor is divided into predominantly radially directed magnetic flux paths (5, 10, 18) in which inductive and homopolar magnetic fluxes (arrows 7 and 6) are superimposed in parallel and which are preferably formed with parallel flanks Magnetic flux paths (5, 10, 18) are provided with such cross sections that they are magnetized by the inducing magnetic fluxes (arrows 7) alone until the beginning of saturation.
