Abstract
A magnet wire having a polyamide-imide outer coating is described which is capable of power insertion into coil slots in a locking wire size range by virtue of a specific lubricant outer coating. The external lubricant comprises a mixture of paraffin wax, hydrogenated triglyceride and an ester lubricant composition comprised of esters of fatty alochols and fatty acids. An internal ester lubricant composition comprised of esters of fatty alcohols and fatty acids can be added to the polyamide-imide coatings to further improve ease of insertability.
