Flat magnet wire is useful in products such as voice coils in loudspeakers, field and armature coils in rotary and linear motors, and transformers, in which the flat wire permits more compact coils and improved heat dissipation, as compared to designs based on round wire.
The wire is produced from round, pre-insulated wire, which is then flattened. This flattening causes only negligible stretching, so the cross sectional area is the same before and after the process. Therefore the insulation is stretched in only one direction, and the resistance and wire gauge remain largely unchanged. |
