Abstract

Die Erfindung offenbart eine elektrische Maschine, aufweisend - zumindest einen ersten Permanentmagnet; - zumindest einen zweiten Permanentmagnet; - einen ersten Bereich, dessen Temperatur sich im Betrieb in einem ersten Temperaturbereich befindet; und - einen zweiten Bereich, dessen Temperatur sich im Betrieb in einem zweiten Temperaturbereich befindet; - wobei der zumindest eine zweite Permanentmagnet eine höhere maximale Arbeitstemperatur als der zweite Permanentmagnet aufweist, wobei sich die maximale Arbeitstemperatur unterhalb der Temperatur befindet, bei der die magnetische Feldstärke des Permanentmagneten temperaturbedingt und aufgrund eines von außen an den Permanentmagnet angelegten magnetischen Feldes irreversibel abnimmt, und wobei der erste Permanentmagnet im ersten Bereich und der zweite Permanentmagnet im zweiten Bereich angeordnet ist.
