| Popis: | Direct-on-line synchronous reluctance motors (DOLSynRM) combine the characteristics of the induction motor (IM) and the synchronous reluctance motor (SynRM). Saturation of core materials, the eddy currents, and the asymmetry of the rotor core and cage make it difficult to predict to which kind of loads the motor can synchronize. In this paper, the DOLSynRM start-up is analyzed with a magnetic field decomposition that makes it possible to quantify and isolate forces between any two distinct parts of an electric machine using a time-stepping finite element (FE) field solution. The results show explicitly, which portion of the motor torque is produced by the rotor core and which by the rotor cage. Compared to conventional static and quasi-stationary analyses used to distinguish between the torque on rotor core and cage, the presented method gives a more detailed view. |
