The aim of continuing the research project is to determine the theoretical and practically achievable improvement potential of the motor efficiency in the entire operating range by using combined star-delta circuits for distributed three-phase windings. The individual examinations should concentrate on machines with small hole numbers, since there the highest improvement potential is to be expected. Asynchronous squirrel-cage motors for grid applications, line-start PM- synchronous motors and inverter-fed synchronous reluctance motors are examined as examples. The specific selection is based on the machines available at the institute and aims to identify differences and exploitable similarities for grid or inverter operation. The research concerns the field of energy-efficient conversion of electrical energy and electric mobility.

继续进行研究项目的目的是通过使用组合的星形 - 戴尔塔电路进行分布式三相绕组来确定整个操作范围内运动效率的理论和实际上可实现的提高潜力。单个检查应集中于具有小孔数量的机器，因为预期有最高的改进潜力。示例检查了用于网格应用，线路启动PM-同步电动机和逆变器同步电动机的异步松鼠笼电动机。特定选择是基于研究所可用的机器，旨在确定网格或逆变器操作的差异和可利用的相似性。该研究涉及电能和电动迁移率的节能转化领域。
