Description
独立請求項の特徴部分に記載された本発明による電気機械の利点は、本発明による回転子溝の形態によって、励磁巻線が、問題を引き起こすことなく、高い充填効率と、僅かな平均巻線長と、電気的に低い抵抗を実現できる点にある。その他にも本発明による溝の幾何学形態、特に回転子円周面における複数の永久磁石の配置構成によれば、永久磁石による付加的な励磁が得られ、特に有利には回転子の構成が低い電気的及び磁気的抵抗獲得のために最適化される。またそのような溝への自動巻回も何の問題もなく可能であり、またそのようにして回転子巻線を部分コイルに分割することも非常に容易である。前記部分コイルは、有利にはローターシャフトの両側で対称に配置することも可能である。これにより回転子の不平衡も最小化される。
