Machine windigs in combined polygon schemes

继续研究项目的目的是通过使用分布式三相绕组的组合星形-三角形电路，确定在整个操作范围内电机效率的理论和实际可实现的改进潜力。个别检查应集中在小孔数量的机器上，因为那里的改进潜力最大。异步鼠笼式电动机电网应用，线启动永磁同步电动机和逆变器供电的同步磁阻电动机作为例子进行检查。具体的选择是基于研究所提供的机器，旨在确定电网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交通的节能转换领域。

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.
