A magnet wire suitable for use in hermetic motors comprising a conductor wire, an insulating intermediate layer, a polyamide outer layer, and an organic polymeric lubricant coating on the outer layer. The lubricant has a pour point below about 15.degree. F. (-9.degree. C.) and wets the outer layer. A preferred lubricant is soluble in monochlorodifluoromethane and in dichlorodifluoromethane, and comprises a saturated C.sub.2 -C.sub.4 ether of ethylene oxide and 1,2-propylene oxide copolymers. A particularly preferred lubricant has a viscosity of about 100 to 400 SUS (21 to 87 centistokes) and a pour point of about -60.degree. F. (-51.degree. C.).

Magnet wire for hermetic motors

A new and improved magnet wire is provided comprising a copper or aluminum conductor, a basecoat consisting of at least one layer of insulating material around and along the length of the conductor and a polyundecaneamide or polydodecaneamide topcoat around and along the length of the basecoat, wherein the topcoat comprises from approximately 5 to 95% of the total coating thickness.
