Abstract

A method to form an agglomerated stator core that includes operations that consist of: Forming stator core segments made of steel which are provided therewith with an inorganic coating; Applying an adhesive insulating coating on both sides of the segments, said coating including a mixture of: An epoxy resin, A hardening agent for said resin, capable of providing a delay in curing at room temperature, together with curing at elevated temperature, A separating filler based on fibers having a diameter of 0.0114-0.0139 mm (0.45-0.55 mil) in an amount sufficient to ensure uniform separation and isolation between said segments, An inorganic filler to facilitate the working viscosity and to keep the glass fibers homogeneously dispersed in the resin and, An organic suitable solvent for the coating application; Remove the solvents from the coated segments; stacking the coated and dried segments by giving them the configuration of an element intended to form at least a substantial portion of the stator core; and pressurizing and treating said element under conditions of temperature and pressure such that a joint is formed between said segments.
