摘要: Manufacturing processes may introduce a significant variability on the magnetic properties of claw pole generator stators. The present work deals with analysis two groups stator samples. first group is composed 28 slinky stators (SS) and second 5 stators, manufactured using laser cut stacked laminations (SL). Both are made from same lamination grade geometrical dimensions. Characterization was carried out for several levels excitation field at 50 Hz. A noticeable has been observed iron losses SS samples, whereas it appears to be not SL loss separation technique then investigated Results show that static more important than one dynamic losses.
