Abstract

The present disclosure describes slot insulation systems for electrical rotating machines. For example, a system may include: a main insulation for a coil of the rotating machine or for an individual bar for the coil; a resin formulation serving as a slot adhesive forming a solid film. At room temperature and under standard conditions, the solid film is in an A-state. Heating the electrical rotating machine to a curing temperature for the resin formulation, the solid film firstly melts and flows within an occupied slot, then cures and solidifies to form a thermoset material.
