Abstract
A magnet wire including a conductor and an insulating coating formed on an outer periphery of the conductor. The insulating coating contains a copolymer containing a tetrafluoroethylene unit and a fluoroalkyl vinyl ether unit. The copolymer has a melt flow rate of 10 to 60 g/10 min, and the copolymer has a fluoroalkyl vinyl ether unit content of 6.2 to 8.0% by mass based on a total content of monomer units.
Claims5
A coil comprising a flat magnet wire comprising
- (i) a flat conductor and an insulating coating formed on an outer periphery thereof, and
- (ii) an insulating coating containing a copolymer (a) which
- contains a tetrafluoroethylene unit and a fluoroalkyl vinyl ether unit,
- has a melt flow rate of 10 to 40 g/10 min, and
- has a fluoroalkyl vinyl ether unit content of 6.2 to 8.0% by mass based on a total content of monomer units,
- wherein the insulating coating contains only the copolymer (a) as a polymer material;
- wherein the coil is formed by bending and winding the flat magnet wire in an edgewise direction.
