Abstract
An object of the present disclosure is to provide a curable epoxy composition for a rotatory electric machine that can easily adhere to PEEK resin and can suppress delamination during use. The epoxy composition for a rotatory electric machine of an embodiment of the present disclosure contains an epoxy compound (A), an acid anhydride-based curing agent (B), and an amine-based curing accelerator (C), is liquid at 25°C, and has a viscosity at 25°C of 3000 mPa·s or less and an adhesive strength to PEEK resin of 2.5 N/cm<sup>2</sup> or more when cured. In the curable epoxy composition for a rotatory electric machine, a viscosity increase rate before and after a storage test performed under conditions of a temperature of 23 ± 5°C and a humidity of 50 ± 5% for 41 days is preferably 20000% or less.
