When a slot is insulated with epoxy resin powder filled by 5, 10, 30 weight percent SiO2 or pure epoxy resin powder, the variation of impulse current wave form do not arise deeply because of the very small diflerences of S1, S2 values.
In the 5 wt % insulation, the electrical weak point which has unevenness between lamination is very small.
Also, electrical properties, easiness of manufacture and improvement of Product Can be enhanced significantly by epoxy resin powder and suitable choice of filler wt % more than insulation paper.
