Application of Silicone Insulation System in Permanent Magnet Traction Motor

Abstract

To study the applicability of silicone insulation systems on permanent magnet traction motors, calculation of silicone insulation system life by accelerated aging and its application in permanent magnet traction motor were carried out. The results showed that the silicone insulation system had excellent heat resistance and stability with life not less than 20 000 hours under the condition of 220℃ , which meets the needs of rail permanent magnet traction motor.
