Machine windigs in combined polygon schemes

继续这一研究项目的目的是确定在整个运行范围内使用星形-德尔塔组合电路对分布式三相绕组的电机效率的理论和实际可实现的改进潜力。个别检查应集中在孔数较小的机器上，因为那里的改进潜力最大。以电网用异步鼠笼电机、线启动永磁同步电机和逆变器供电的同步磁阻电机为例进行了研究。具体的选择是基于研究所现有的机器，旨在确定电网或逆变器运行的差异和可利用的相似性。这项研究涉及电能的节能转换和电力机动性领域。

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.
