摘要： In an encased electric motor within a casing, an electrically insulating varnish is applied by vacuum impregnation to the inside surfaces of the casing and to the outer surface of the stator of the motor. The remaining empty space within the casing is filled with a heat conducting gas mixture comprising approximately 60-90% by volume of helium, with the remaining percentage being an electrically insulating gas having better electrically insulating properties than helium, such as sulphur hexafluoride. This encased motor is much lighter than conventional encased motors in which the stator enclosure is filled with a heat conducting resin potting compound and avoids warping damage which frequently occurs in conventional encased motors due to thermal expansion of the heat conducting resin potting compound.
摘要翻译： 在壳体内的电动马达中，通过真空浸渍将电绝缘清漆施加到壳体的内表面和电动机的定子的外表面。 壳体内的剩余空间填充有包含约60-90体积％的氦的导热气体混合物，其余百分比是具有比氦更好的电绝缘性能的电绝缘气体，例如六氟化硫。 这种封装的电动机比常规封装的电动机要轻得多，其中定子外壳上装有导热树脂封装复合材料，并且避免了由于导热树脂封装材料的热膨胀而在传统封装的电动机中频繁发生的翘曲损坏。
