Litz wire is made of several strands of enameled wires that are twisted together.
In order to suppress the deterioration of properties caused by the skin effect due to high frequency currents, twisted groupings of wires continue to be used in a wide variety of fields.
For characteristics evaluation of wire material twisting condition, however, the complex twisted wire configuration makes construction of a 3D analysis model difficult; because of the difficulty in predicting the mesh size and calculation time, this creates complexities in proceeding with a detailed evaluation using the finite analysis method.
In this presentation, we will discuss effects of the twisted state on the characteristics, as well as the current state of analysis environments through JMAG’s Litz wire analysis.
