Motors & Generators


PUCARO Pressspan, Triflexil® and Ecoflexil® are used in Motors and Generators as slot insulation, slot closure and layer insulation.


The selection of flexible insulating materials in motors and generators is made in consideration of temperature and voltage. For rotating devices with short-time duty cycles, there are class A (105°C) laminates with one- and mutli-layer combinations of press paper and class B (130°C) laminates with polyester films (F-PET). For higher temperatures and duties, laminates with additional coatings as well as combinations of aramid paper with polyester films are used. For 200°C and above applications, the laminates consist of aramid paper and polyimid films.
