FREMGANGSMAATE FOR FREMSTILLING AV EN VIKLING I EN ELEKTRISK MASKIN.

摘要

With stator windings impregnated by total immersion, the gap formation between main insulation (7) and slot side possibly occurring due to the different expansion of conductor material and insulation material is avoided by several successive impregnation and curing processes being made (at least two), each further curing being performed at a lower temperature level (difference about 20 DEG C.) beginning at approximately the class temperature of the insulation system and the curing being performed with horizontal stator axis, the stator being turned through at least 90 DEG C. before each further process.
