Abstract
A stator structure for an electric motor comprising stator windings formed with conductors coated with an insulation, such as polyetheretherketone (PEEK). At least one portion of such windings has an adhesion-resistant agent, such as a thin coat of mineral oil, applied thereto prior to the application thereto of an immobilization agent, such as a varnish. The adhesion-resistant agent prevents subsequent bending of the windings from damaging the underlying insulation thereon during the manufacture and operation of the electric motor. The prevention of such insulation damage reduces the likelihood of resulting premature motor failure.
