Abstract: Two typical insulation structures of the stator notch were introduced, and the conventional electrical properties and electrical aging properties of the wide and non-wide stator notch were compared. The results showed that the two insulation structures of stator notch could provide a certain protective effect for insulation performance of the winding while the wide stator notch had more prominent performances on the failure time of electrical aging, the distribution of the breakdown place and other aspects of process consistency.
