A magnet wire having a nylon 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 and hydrogenated triglyceride. An internal lubricant composition comprised of esters of fatty alcohols and fatty acids and/or hydrogenated triglyceride can be added to the nylon coatings to provide greater ease of insertability.

Power insertable nylon coated magnet wire

A selfbonding magnet wire is disclosed having an outer bondable coating of nylon 612. In addition to improved bonding properties, the magnet wire has improved moisture resistance and solvent resistance so as to be useful in hermetic motor environment. Overcoated with appropriate external and/or internal lubricant, it can also be power inserted in locking wire size range. The nylon 612 can be used as a sole insulation coat or part of a multicoat system, for example, overcoated on polyester or polyamideimide overcoated polyester. The nylon 612 can also be used as a blend with nylon 11.

Self-bonding magnet wire

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 and hydrogenated triglyceride. An internal lubricant composition comprised of esters of fatty alcohols and fatty acids can be added to the polyamide-imide coatings to provide greater ease of insertability.

The lubricant comprises a mixture of paraffin wax, hydrogenated triglyceride and ester lubricant composition comprising esters of fatty alcohols and fatty acids. An internal ester lubricant composition comprised of esters of fatty alcohols and fatty acids and/or an internal hydrogenated triglyceride lubricant composition can be added to the nylon coatings to further improve ease of insertability.

Method of power inserting nylon coated magnet wire

A magnet wire having a polyamide-imide outer coating is described which is capable of multiple winding power insertion into coil slots without damage by virtue of an improved lubricant outer coating. The lubricant comprises a mixture of oleic acid, beeswax, fluorocarbon surfactant and paraffin wax.
