Infiltration type evaporative cooling is superior to other cooling methods. It offers a safe and reliable operating environment which can provide effective stator insulation and heat transfer . Taking a high power density and high speed commutate asynchronous generator as research object ,and according to the manufacturer ′s possible technic condition , this paper introduced a new type of stator insulation structure adapting to evaporative cooling mode , gave a systematic analysis and calculation on electric field distribution of the new insulation system by using FEM and a simulation software. The results provide theoretical foundation for designing similar generator.
