To provide: a method for operating an electric motor or corresponding electric drive system securely and reliably in high load ranges; and the electric drive system.SOLUTION: An electric drive system (20) comprises: an electric machine (27) that comprises a first multiphase winding operatively coupled to a first inverter (25), and at least one second multiphase winding coupled to a second inverter (26); a first energy storage means (23) arranged upstream of the first inverter (25); and a second energy storage means (24) arranged upstream of the second inverter (26). The method includes: operating the electric machine (27) by providing a first power flow between the first energy storage means (23) and the first multiphase winding; and connecting the second inverter (26) so that a second power flow can be provided between the first energy storage means (24) and the second multiphase winding.SELECTED DRAWING: Figure 2

    【課題】高負荷レンジで電気モータ又は対応する電気駆動システムを安全かつ確実に動作させる方法及び電気駆動システムを提供する。【解決手段】電気駆動システム(20)は、電気機械(27)が、第1のインバータ(25)に動作可能に接続されている第1の多相巻線を備え、かつ、第2のインバータ(26)に接続される少なくとも1つの第2の多相巻線を備え、第1のエネルギー貯蔵手段(23)が、第1のインバータ(25)の上流に配置され、第2のエネルギー貯蔵手段(24)が第2のインバータ(26)の上流に配置される。方法は、第1のエネルギー貯蔵手段(23)と第1の多相巻線との間に第1の電力の流れを提供することによって、電気機械(27)を動作することと、第1のエネルギー貯蔵手段(24)と第2の多相巻線との間に第2の電力の流れが提供されるように、第2のインバータ(26)を接続することと、を含む。【選択図】図2
