The paper is aimed at the enhancement of the starting performance of single phase line-start permanent magnet synchronous machines (PMSMs). These are characterized by a tapered air gap that enables to overcome their starting limitation. The study is initiated by a 2D finite element analysis (FEA)-based investigation of the electromagnetic features of a single phase line-start PMSM. Then, the FEA is extended to a geometrical sizing of the machine. The FEA is achieved by the investigation of the effect of the variation of the relative position of a two notches in the rotor poles, with emphasis on the increase of the cogging torque mean value. This approach makes it possible the enhancement of the machine starting capability.

Then, the FEA is extended to a geometrical sizing of the machine. The FEA is achieved by the investigation of the effect of the variation of the relative position of a two notches in the rotor poles, with emphasis on the increase of the cogging torque mean value. This approach makes it possible the enhancement of the machine starting capability.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
